* Undo syntax changes preventing VeriFast parsing * Update proofs inline with source changes Outstanding: - xQueueGenericReset return code - Not using prvIncrementQueueTxLock or prvIncrementQueueRxLock macros * Remove git hash check * Document new changes between proven code and implementation * Update copyright header * VeriFast proofs: turn off uncrustify checks Uncrustify requires formatting of comments that is at odds with VeriFast's proof annotations, which are contained within comments. * Update ci.yml Co-authored-by: Joseph Julicher <jjulicher@mac.com> Co-authored-by: Aniruddha Kanhere <60444055+AniruddhaKanhere@users.noreply.github.com>
