      recovery: use __android_log_pmsg_file_write for log files · 13aca598
      Mark Salyzyn authored
      (cherry-pick from commit a4f701af)
      
      - Add call to __android_log_pmsg_file_write for recovery logging.
      - Add call to refresh pmsg if we reboot back into recovery and then
        allow overwrite of those logs.
      - Add a new one-time executable recovery-refresh that refreshes pmsg
        in post-fs phase of init. We rely on pmsg eventually scrolling off
        to age the content after recovery-persist has done its job.
      - Add a new one-time executable recovery-persist that transfers from
        pmsg to /data/misc/recovery/ directory if /cache is not mounted
        in post-fs-data phase of init.
      - Build and appropriately trigger the above two as required if
        BOARD_CACHEIMAGE_PARTITION_SIZE is undefined.
      - Add some simple unit tests
      
      NB: Test failure is expected on systems that do not deliver either
      the recovery-persist or recovery-refresh executables, e.g. systems
      with /cache. Tests also require a timely reboot sequence of test
      to truly verify, tests provide guidance on stderr to direct.
