f3d61015f7 build: Fix problems with building kconfig and generating sdkconfig
We had some problems:
    simultaneous compiling of kconfig in the same tree;
    attempt to use menuconfig in some examples and ut in batch mode (w/o interactive console)

Also increase debug abilities in CI:
    force non-interactive building;
    add variable DEBUG_SHELL to toggle verbosity of scripts

82fb2768aa build system: trim crosstool-ng commit ID when checking version
Since 2.11.0, git does not default to 7 characters for short commit IDs,
instead automatically estimating the number of characters based on
repository size [1]. If the toolchain was compiled on a computer with
new version of git installed, commit ID will contain 8 characters, and
the check for the toolchain version will fail. As a workaround, trim the
commit ID to 7 characters when checking the version.

cdc7396f97 Make sure LD -L option is calculated correctly when the project Makefile has specified SRCDIRS components that are not directly below Makefile folder level.
For example,
SRCDIRS = comp_a  happy/comp_b  /c/dev/comp_c

Then the following are built:
build/comp_a/libcomp_a.a
build/comp_b/libcomp_b.a
build/comp_c/libcomp_c.a

But when LD is run the -L is calculated as follows
-L build/comp_a
-L build/happy/comp_b
-L build//c/dev/comp_c

This means comp_b and comp_c are not found by LD. With this change set -L is calculated correctly for comp_b and comp_c

Version parameter was added in git 2.11, while default git on macOS is

parameter is not provided, it defaults to ‘v1’, so removing it doesn’t

02fdf8271d Merge branch 'feature/idf_monitor' into 'master'
Expand  'make monitor' support

New 'make monitor' idf_monitor tool for better monitor output. Running 'make monitor' will now:
* Automatically look up code addresses via addr2line and print function, source file, line number in terminal.
* Can reset the ESP32 by typing Ctrl-T Ctrl-R.
* Can run "make flash" by typing Ctrl-T Ctrl-F.
* Can run "make app-flash" by typing Ctrl-T Ctrl-A.
* If gdb stub starts, monitor will automatically run gdb and connect. When gdb exits, ESP32 resets and monitor resumes.
* Exit is still Ctrl-[

Have some more features I'd like to add (log output to file, crash dump support) but I think this is at the point of being useful.

Ivan Grokhotkov
61c33ca24e make: don’t override TEST_COMPONENTS
When idf_monitor is launched from make, it gets modified TEST_COMPONENTS
variable which contains full paths to the test components instead of the
names. This causes TEST_COMPONENT_PATHS to be empty and the unit test
app gets built without any test components.

This change introduces an internal TEST_COMPONENTS_LIST variable which
gets set either from $(COMPONENTS) if TESTS_ALL is 1, and from
TEST_COMOPONENTS otherwise.
Bootloader makefile is also fixed to avoid propagating TESTS_ALL to the
bootloader build step.

e91d436e45 build system: Probable fix for errors due to bad config bypassing components
See github #311 https://github.com/espressif/esp-idf/issues/311

Should fix weird compiler/linker bugs where config says something is
enabled, but build system says it is disabled.
Particularly noticeable when WiFi/BT libraries fail to
compile/link despite being enabled.

Underlying cause is configuration file regenerating, but component
Makefiles not reevaluating.

Entirely removes the idea that we don't need to generate config for some
targets (like 'clean'). We need valid config for these targets,
otherwise they don't know which files to clean (etc).

aece3d6fc6 Merge branch 'bugfix/mbedtls_tests' into 'master'
fix mbedtls unit tests, fix IDF_VER when building a project outside ESP-IDF tree

- mbedTLS test needs about 5% more time to run (in debug mode) when building with 5.2.0, compared to 4.8.5. Increase the timeout to let the test pass.
- when doing `git describe` in IDF_VER definition, `-C $(IDF_PATH)` is needed to get the version of ESP-IDF, and not the project being built (which may not even be in git)

New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.

Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.

This works because all CONFIG variables are exported into child make processes.

830e5caf4d build system: Replace get_variable target w/ component_project_vars.mk generated makefiles
Reduces number of make invocations, allows variables exported in project
to be seen in all component make processes, not just the main ones.

Also makes a no-op build about 3x faster than it was.

4f704ac2fe Merge branch 'feature/release_build' into 'master'
Add menuconfig setting for optimization level

This change adds two options (Debug/Release) for optimization level.
- Debug (default) enables -O0
- Release enables -Os and adds `-DNDEBUG`, which removes all assert() statements

These options may be overriden at project level by adding necessary flags to CFLAGS/CXXFLAGS.

Debugging symbols are kept in both cases, although we may add an option to strip output file if necessary.

Also we used to define all common compiler flags in CPPFLAGS, and then prepended them to CFLAGS/CXXFLAGS.
It made it impossible to add preprocessor macros to CPPFLAGS at component level (one had to use CFLAGS/CXXFLAGS instead).
Some third party libraries are not compatible with this approach. Changed to the more common way of using these variables.

CI will build both debug (default) and release.
