The two functions check_wipe_package() and check_newer_ab_build() were
using the same flow; and checked the same device properties against the
metadata file in the package. These properties include: ota_type,
pre-device, and serial number.
Therefore, we can consolidate the checks to a single function; and
continue to check the fingerprint and timestamp only for AB updates.
This change also addresses the need to accept multiple serial number in
the wipe package.

We have a general need for overriding more paths (e.g. "/tmp"), mostly
for testing purpose. Rename CacheLocation to Paths, and use that to
manage TEMPORARY_{INSTALL,LOG}_FILE.

verify_package_compatibility() is added to parse the compatibility entry
(compatibility.zip) in a given OTA package. If entry is present, the
information is sent to libvintf to check the compatibility.
This CL doesn't actually call libvintf, since the API there is not
available yet.

This reverts commit 8584fcf677.
This CL re-lands commit c0319b60f5.
The "stage" and "reason" variables are now declared as global by
dropping the static qualifier, because they may be used by vendor
recovery libraries.

To increase the security of wiping A/B devices, let uncrypt write
wipe package in misc partition. Then recovery verifies the wipe
package before wiping the device.
Based on the original cherrypick, this CL also has additional changes to
address the LOG statements and libziparchive changes.

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)

(cherry picked from commit 3c62b67faf)
Implement a new method of sideloading over ADB that does not require
the entire package to be held in RAM (useful for low-RAM devices and
devices using block OTA where we'd rather have more RAM available for
binary patching).
We communicate with the host using a new adb service called
"sideload-host", which makes the host act as a server, sending us
different parts of the package file on request.
We create a FUSE filesystem that creates a virtual file
"/sideload/package.zip" that is backed by the ADB connection -- users
see a normal file, but when they read from the file we're actually
fetching the data from the adb host. This file is then passed to the
verification and installation systems like any other.
To prevent a malicious adb host implementation from serving different
data to the verification and installation phases of sideloading, the
FUSE filesystem verifies that the contents of the file don't change
between reads -- every time we fetch a block from the host we compare
its hash to the previous hash for that block (if it was read before)
and cause the read to fail if it changes.
One necessary change is that the minadbd started by recovery in
sideload mode no longer drops its root privileges (they're needed to
mount the FUSE filesystem). We rely on SELinux enforcement to
restrict the set of things that can be accessed.

- recovery takes a --locale argument, which will be passed by the main
system
- the locale is saved in cache, in case the --locale argument is
missing (eg, when recovery is started from fastboot)
- we include images that have prerendered text for many locales
- we split the background states into four (installing update,
erasing, no command, error) so that appropriate text can be shown.

updater now has a function "wipe_cache();" which causes recovery to
wipe the cache partition after the successful installation of the
package. Move log copying around a bit so logs and the last_install
flag file are copied to cache after it's wiped.
