Move supplicant to idf and do following refactoring:
1. Make the folder structure consitent with supplicant upstream
2. Remove duplicated header files and minimize the public header files
3. Refactor for WiFi/supplicant interfaces
esptool_py used to create its own custom target to attach properties to.
This commit uses component properties instead, and the APIs used to set
and retrieve those properties in order to simplify generation of
argument files to esptool.py.
Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.
Misc. variables name corrections
Bootloader build requires verification key to be embedded in the binary.
Under specific configs, this key is generated during build time from the
signing key. Move the key generation to after the component
registration, since non scriptable commands are used in the process
(during early expansion)
Path was accidentally generated as build/<absolute path to input file> which creates unexpected path structure on Linux/macOS and breaks Windows (as can't have a directory named "C:".

esptool_py defines command `esptool_py_flash_project_args` that
generates arg file for esptool.py. Two of the arguments are the offset

This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a

print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

!4452 and !4897 made some ill-advised corrections to dependency info;
revert those in this MR. Handling pre-built binaries as imported
libraries is retained, however.
!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.
The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
Previously ldgen determines the output file name on its own. This commit
makes it so that user can dictate what the output file name will be
for the processed template, if the user needs it for something else.
Since !4452 the common component requirements automatically get
privately linked to libraries built under ESP-IDF build system (this
includes targets from third-party libraries). This removes a variable
that was used for that purpose before !4452.
Since the internal target names were changed, the compile definition for
warning on using deprecated functions is not being passed. Since using
the internal name is unreliable, prefer passing this compile definition
from the test itself.

open_fn() was introduced in the context of HTTPS server, as a configurable callback function that is called by the HTTP server, on every newly created socket. It is responsible of allocating resources for per session transport security.
Earlier, if open_fn were to fail, the newly created socket would be closed by the server but the corresponding entry, for the now invalid socket, will remain in the internal socket database until that invalid socket is detected due to error when calling select(). Because of this delayed closing of sockets, the HTTPS server would quickly face shortage of available sessions when a lot of SSL handshake errors are happening (this typically occurs when a browser finds that the server certificate is self signed). This changes in this MR fix this issue by clearing up the socket from internal database, right after open_fn fails.

When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.
The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.

Fixes an issue with post instance data preparation. Currently, there is
no way to check if event data has really been set during handler
execution preparation. When data is not allocated from the heap, user
could have passed 0x0 which can lead to failed checks.
This also implements using the already allocated data memory for posting
events from non-ISR functions when data size is less than the capacity.
Fixed the case when the first part of log was missed
this was happened when:
* CONFIG_CONSOLE_UART_CUSTOM option is selected (UART1)
* The selected CONSOLE_UART port is used also for the console component
* in code esp_restart() or abort() functions were called.
Hardware AES-CBC performance changes:
Release config 11.0MB/sec -> 10.8MB/sec
Debug config 9.4MB/sec -> 9.8MB/sec
(Unrolling the loop to optimize the check improves
performance at -Og, even with the fault check.)
Issue is that when users creates a custom bootloader from
$IDF_PATH/components/bootloader. Parent project build uses the copy but
bootloader subproject build uses the original still. The issue is solved
by passing the custom bootloader as extra component directory so

According to the documentation[1][2] for partitions, setting the encrypted
flag for partitions should be a no-op when system level encryption isn't
enabled. The current implementation, however, does not actually match
the documentation and it ends up with an unreadable partition via the
partition API if a partition flag is marked as encrypted without
system-level encryption enabled. (This is because the writes go through
the encryption block, and reads do not go through the encryption block
when this situation occurs causing unreadable data to the application
running.) This fixes up the read-back of the partition table to match
whether or not the partition is currently encrypted under the hood.
This should not affect the bootloader's code for reading/writing encrypted
partitions as the bootloader directly invokes the spi_flash_write*(...)
APIs.

This prevents wear and tear on the flash, and it also is faster in some
cases since the read-out of flash is a cheaper operation than the erasure
of flash. Some library modules (such as the esp_wifi) write out to NVS
upon every initialization without checking first that the existing value
is the same, and this speeds up initialization of modules that make
these design choices and moves it into a centralized place.
The comparison functions are based on the read-out functions of the same
name, and changes out the memcpy(...) operations for memcmp(...)
operations.

This MR removes the common dependency from every IDF components to the SOC component.
Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.
In CMAKE, we have two kinds of header visibilities (set by include path visibility):
(Assume component A --(depends on)--> B, B is the current component)
1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)
and we have two kinds of depending ways:
(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)
1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)
1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)
This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:
- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h
The major broken include chain includes:
1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h
some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h

This prevents a device from being bricked in case when both secure boot & flash encryption are enabled and encryption gets interrupted during first boot. After interruption, all partitions on the device need to be reflashed (including the bootloader).
List of changes:
* Secure boot key generation and bootloader digest generation logic, implemented inside function esp_secure_boot_permanently_enable(), has been pulled out into new API esp_secure_boot_generate_digest(). The enabling of R/W protection of secure boot key on EFUSE still happens inside esp_secure_boot_permanently_enable()
* Now esp_secure_boot_permanently_enable() is called only after flash encryption process completes
* esp_secure_boot_generate_digest() is called before flash encryption process starts
Earlier eraseItem function in Storage class would do lazy cleanup of
multi-page blobs if called using type "ANY" instead of "BLOB". It used to
just delete BLOB data and index would remain as is. Any subsequent read
would delete index entry as well. This however would return a valid
length without error if nvs_get_blob API was just used for finding
length and not reading the complete blob. This change fixes this issue.

stdatomic.h is available both in newlib and GCC include directories.
Normally (if you invoke the compiler without any flags) GCC include
directories are first on the list, so GCC’s stdatomic.h is used. In
IDF, we used to pass newlib include path as an extra include
directory, so newlib’s stdint.h got included instead.
Newlib 2.2.0 stdatomic implementation is compatible with -std=gnu99
but incompatible with -std=gnu11. And GCC doesn’t support atomic_load
with -std=gnu99 (it’s a C11 feature). So when we used atomic_load
with -std=gnu99, it worked due to newlib’s header.
Since we are no longer going to be including newlib headers into IDF,
GCC stdatomic will be used instead. Hence, add -std=gnu11 for source
files which use atomic features.
Operation:
In `esp_http_client_set_url`, we check for if old_host is same as new_host.
Delete and open new connection if host is different.
Issue:
We just pointed `client->connection_info.host` to `old_host` and reassigned it.
This made old_host and new_host always point to same location and hence, using old_host with new request.
Fix:
Made a separate copy for old_host using strdup.
