Angus Gratton f6cd55d2ac config: Rename mconf to mconf-idf & conf to conf-idf
These versions of conf/mconf are forked from the upstream, and the CMake system allows mconf-idf to
be installed externally on the path. So the best option is to rename.

Includes changes to Windows installer for v1.1

Ivan Grokhotkov 790049b3dd build: remove some debug lines printed when V=0
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.

Mahavir Jain 344e757a6a make: remove build system dependency on `git` using some hooks
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.

Angus Gratton 5b05a1f822 make: Build out of tree component srcs under component build dir
Strips leading ../ when generating object file paths, keeps these in sync with the source files
otherwise.

This prevents object files landing in other directories, including outside the build directory, if
the component_srcdirs start with ../

Ivan Grokhotkov 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.

Eyob 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

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 a9ed6d5a24 Merge branch 'bugfix/make_test_components' into 'master'
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, or from
`TEST_COMOPONENTS` otherwise.
Bootloader makefile is also fixed to avoid propagating `TESTS_ALL` to the

Angus Gratton f29768c404 Build system: Add new BATCH_BUILD flag to disable interactive parts of the build
Mostly useful for Eclipse (where accidentally running interactive
config hangs the build), but also good for CI and other automated
build systems.

Angus Gratton 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).

Ivan Grokhotkov 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)
