recovery: use __android_log_pmsg_file_write for log files

(cherry-pick from commit a4f701af93a5a739f34823cde0c493dfbc63537a)

- 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.

The Recovery Image

Quick turn-around testing

mm -j && m ramdisk-nodeps && m recoveryimage-nodeps

# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img

Running the tests

# After setting up environment and lunch.
mmma -j bootable/recovery

# Running the tests on device.
adb root
adb sync data

# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test

# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
