facab8c5a7 tools: Increase the minimal supported CMake version to 3.16
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.

e6d43ab56f freertos: Update SMP idle hooks
This commit updates the usage of idle hooks in SMP FreeRTOS as follows:

- IDF style idle hooks are now called from vApplicationMinimalIdleHook()
- If the user provdies their own vApplicationMinimalIdleHook(), it can be
  wrapped using -Wl,--wrap if CONFIG_FREERTOS_USE_MINIMAL_IDLE_HOOK is
  enabled.
- SMP port no longer uses vApplicationIdleHook() as it's only called from
  the prvIdleTask() and not every prvMinimalIdleTask()

9901fc3058 cmake: don't pass --gc-sections to macOS linker, use -dead_strip

is normally used. MacOS linker doesn't recognise --gc-sections, but
has a -dead_strip flag which is equivalent.

To make the transition from 32-bit time_t to 64-bit time_t smoother,
detect the size of this type in CMake and remove the manual option in
Kconfig.
The information about 64-bit time_t support is moved from Kconfig help
string into the "system time" section of the API reference.

0baf2c43cc Build: CMake compiler flags will be set, regardless of the cache status
Defining CMake variables from the command-line or from another CMake project,
such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP
CMake was unable to set its proper compilation flags.
Additional CMake compiler flags can now be provided by another project.

0771bd1711 espsystem: Rearchitecture and fix eh_frame_parser bugs
eh_frame_parser is architecture independent, thus the files have
been rearchitectured. Some bugs have been fixed in the test.
A README file has also been added to eh_frame_parser host test
directory.

eh_frame_parser is now able to detect empty gaps in .eh_frame_hdr
table (missing DWARF information).
Fix a bug occuring when parsing backtraces originated from abort().
Fix build missing dependencies issue.

b967dc0dbf espsystem: add support for RISC-V panic backtrace
Add .eh_frame and .eh_frame_hdr sections to the binary (can be
enabled/disabled within menuconfig). These sections are parsed
when a panic occurs. Their DWARF instructions are decoded and
executed at runtime, to retrieve the whole backtrace. This
parser has been tested on both RISC-V and x86 architectures.

This feature needs esptool's merge adjacent ELF sections feature.

f49a78d543 build system: explicitly disable LTO plugin
... to reduce the number of simultaneously open files at link time.

When plugin support is enabled in the linker, BFD's (and the
corresponding file handles) are cached for the plugin to use. This
results in quite a large number of simultaneously open files, which
hits the default limit on macOS (256 files).

Since we aren't using LTO now, disable it explicitly when invoking the
linker.

499d087c91 C++: add provisions for optional RTTI support
Ref. https://github.com/espressif/esp-idf/issues/1684

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.

4fdaeb6b6e cmake: Add new compiler optimization levels definitions
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.

3882e48e8a cmake: use new signature form of target_link_library to link components
!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

Reverting (for now) the change in !4452 to use EXCLUDE_FROM_ALL.

not causing them to be built with the project.

This is apparently a bug which has a merged fix:
