When recovery starts with --brick, it tries to brick the device by
securely wiping all the partitions as listed in /etc/recovery.brick.
This is designed to support bricking lost devices.

Write error code, cause code, and retry count into last_install. So we
can have more information about the reason of a failed OTA.
Example of new last_install:
@/cache/recovery/block.map package name
0 install result
retry: 1 retry count (new)
error: 30 error code (new)
cause: 12 error cause (new)

An OTA may be skipped due to low battery. But we should always log it to
understand why an update _fails_ to apply.

Add a new command "--security" to boot commands. If this command is
observed as part of BCB, choose a different background text picture
for installing stage in recovery UI. As a result, users will see
"installing security update" instead of "installing system update"
when applying a security update package.

Switch to a Wear-like intro/loop system. We don't have an intro yet,
but hopefully this will let Wear delete more code when they move to N.
Unlike them, we don't hard-code the number of frames: we just look to
see what we have available. We do hard-code the fps though.
Also add a graphics test mode so you can see a demo of the UI components
without having to actually apply an OTA.
Also fix a bug where default locale is null rather than en-US: it's
more useful to show _some_ text if we don't have a locale (which should
only be during development anyway).

(cherry-pick from commit a4f701af93)
- 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.

When I/O error happens, reboot and retry installation two times

(cherry picked from commit 3c62b67faf)
Since we may not have /cache partition on A/B devices, let recovery
handle /cache related operations gracefully if /cache doesn't exist.
(1) Disable the wipe for /cache partition.
(2) Skip wiping /cache while wiping /data (i.e. factory reset).
(3) Disable logging-related features, until we figure out better
ways / places to store recovery logs (mainly for factory resets on A/B
devices).

For applying update from SD card, we used to use a thread to serve the
file with fuse. Since accessing through fuse involves going from kernel
to userspace to kernel, it may run into deadlock (e.g. for mmap_sem)
when a page fault occurs. Switch to using a process instead.

Fork a logger process and send over the log lines through a pipe.
Prepend a timestamp to each line for debugging purpose. Timestamps are
relative to the start of the logger.

When calling ScreenRecoveryUI::ShowFile(), the only thing that gets
inadequately logged is the progress bar. Replace the call to
ScreenRecoveryUI::Print() with ScreenRecoveryUI::PrintOnScreenOnly() for
the progress bar, so we can avoid calling redirect_stdio().

Malloc might fail when replacing package path. In this case, print a
clear error message in the logs and let the OTA fails.

When system images contain the root directory, there is no entry of
"/system" in the fstab. Change it to look for "/" instead if
ro.build.system_root_image is true. We actually mount the partition
to /system_root instead, and create a symlink to /system_root/system
for /system. This allows "adb shell" to work properly.
