Change the default bootloader config to -Os to save size.
This is a useful feature because it allows switching between debug
and release configs in the app without also needing to account for a
size change in the bootloader.

Also, for full RTTI support, libstdc++.a in the toolchain should be built
in both with RTTI and w/o RTTI options. Multilib with -fno-rtti
flag is used for that.
Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.

This change allows RTTI to be enabled in menuconfig. For full RTTI
support, libstdc++.a in the toolchain should be built without
-fno-rtti, as it is done now.
Generally if libstdc++.a is built with RTTI, applications which do not
use RTTI (and build with -fno-rtti) could still include typeinfo
structures referenced from STL classes’ vtables. This change works
around this, by moving all typeinfo structures from libstdc++.a into
a non-loadable section, placed into a non-existent memory region
starting at address 0. This can be done because when the application
is compiled with -fno-rtti, typeinfo structures are not used at run
time. This way, typeinfo structures do not contribute to the
application binary size.
If the application is build with RTTI support, typeinfo structures are
linked into the application .rodata section as usual.
Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.
Rename and add multiple kconfig compiler options. New compiler options
COMPILER_OPTIMIZATION_PERF and COMPILER_OPTIMIZATION_NONE have been added.
Optimize "Debug" and "Release" options to "Default" and "Size" respectively.
This commit also does the following:
- The COMPILER_OPTIMIZATION_PERF option introduced multiple bug.
This commit fixes those bugs.
- build.yml also updated to test for the new optimization options.
Previously, V=0 would print some verbose lines but not most of them.
This meant that it was impossible to disable all verbose output
when BATCH_BUILD=1

* Fix the situation where component_project_vars.mk is generated before config exists
* Does not fix situation where config is changed and component_project_vars.mk contents should be
changed. This may still require a rebuild.
1. When one of the COMPONENT_DIRS points to a component directory
(i.e. a directory containing component.mk, not a directory of multiple
components), and there is a subdirectory in it which also contains
a component, the subdirectory was mistakenly added to the list of
components and compiled.
For example:
main/
component.mk
main.c
test/
component.mk
test_main.c
Would compile test_main.c and link libtest.a.
2. When one of the COMPONENT_DIRS points to a component directory, and
the parent directory contained a directory with the same name as
another component, that directory would be mistakenly added to the
COMPONENT_PATHS.
For example:
esp/
esp-idf/
esp32/
(random stuff)
mycomponent/
component.mk
mycomponent.c
myproject/
main/
Makefile
and Makefile sets EXTRA_COMPONENT_DIRS=$(realpath ../mycomponent),
then "esp32" directory which is at the same level as mycomponent
was added to COMPONENT_PATHS.
3. If EXTRA_COMPONENT_DIRS pointed to a directory with a list of
components, and one of the subdirectories was not a component, but
had the same name as another component, than that directory would be
mistakenly added to COMPONENT_PATHS instead of the real esp32
component directory.
For example:
my_components/
my_component/
component.mk
my_component.c
esp32/
(some random stuff)
and EXTRA_COMPONENT_DIRS would point to my_components/, then "esp32"
directory would be added to COMPONENT_PATHS instead of the real esp32
component directory.
Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
Add a command `make erase_ota` - erases otadata if it there is in the
partition table otherwise error 'Partition table does not have ota_data partition'.
Closes https://github.com/espressif/esp-idf/issues/1821
Allows you to move the partition table, it gives more space for the bootloader.
Added a new utility - parttool.py. This utility can search for the offset and/or size of the partitions by name and type/subtype. Use for getting APP_OFFSET and PHY_DATA_OFFSET.
The linker(esp32.bootloader.ld) made changes that allow you to write a custom bootloader code more.

With V=0, build process would print “including .../Makefile.projbuild" lines, causing problems for print_flash_cmd target.
The issue was due to the way macro expansion works in make. To delay evaluation of info function until the execution of expanded block, two dollar signs are required.
Test for print_flash_cmd target added.
Currently for checking IDF version and submodules existence,
build system uses `git` commands. But, it could be possible use-case
where `git` is not installed (assuming IDF is flattened in source format)
on system and build happens without any warnings.
