This reverts commit 569c78fd8c.
* Update freertos Kernel submodule to latest head
* Remove temporary files
* Fix MingW demos and spell check
* Fix manifest version; fix headers
* Add ignore files and paths to core-checker.py
* Fix copyright in remaining files
* Fix PR check build failure
1. Remove defining `inline` in Makefile. This was causing build
warnings.
2. Ensure that the linker removed unused functions from various
compilation units.
3. Update the linker script so that all the functions are correctly
