This commit updates variousf pytest scripts to expect
"main_task: Calling app_main()" instead of "cpu_start: Starting scheduler" as
indicator of the start of an application.
* Added port layer from the FreeRTOS POSIX port, added
additional port code for ESP-IDF.
* Created another hello world example using that POSIX
port in tools/test_apps.
* Removed old linux app
Many of the more complicated CMake projects can't be added to the IDF
build system simply by calling add_subdirectory.
"add_subdirectory" also cannot be used with projects which use build
systems other than CMake (for example GNU Make or cargo).
This commit changes the example to use ExternalProject_Add, instead,
which is a more general way of adding subprojects.
As part of this change, tinyxml2 is now downloaded from the Internet,
which allows removing one submodule.
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.
After refactoring the target components (e.g. esp32) no longer contained any real functionality.
What remained in these components have been moved elsewhere and the component itself deleted from the
build system.
This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
This example shows how to use ESP-IDF build system features to build
multiple configurations of an app from the same source files.
Configurations are set by overriding SDKCONFIG_DEFAULTS variable when
invoking idf.py.

* add toolchain file
* add linux to preview targets
* add stub for dfu number in cmake
* excluded unity runner per default
* Added esp_attr.h and esp_partition.h linux stubs
* component.cmake check list for emptyness
* added switch for linux in unity cmake file
* Added Linux host example app
Also add some explanation about configuring the project in the README
Previously with the default build-esp32.sh script, the build directory was
deleted and recreated so the project would always be built with default config.
GCC prefixes underscore on symbol names on macOS, and so the set
undefined symbol `-u app_main` won't work. However, this is unecessary,
as the source file that defines it is specified directly to the
executable, and not through a static library.
