We used to convert a pem certificate file to some intermediate plain
text format; and parse that format under recovery mode. This is
uncessary since the x509.pem can be directly parsed with openssl
functions.
Add the function to load the public key from one x509.pem file and
corresponding unit tests. And we will add more cls to extract the pem
files from otacert.zip later.

of a format error in the care map.

The recovery-persist used to look for the related recovery logs in
persist storage, and copy them under /data/misc/recovery during the
normal boot process.
As we also want to find out the sideload information from last_install,
it makes more sense to move the parse & report of non-a/b metrics to
recovery-persist. Thus we can avoid the race condition of the file
system between the native code and RecoverySystem.

applypatch() was initially designed for file-based OTA, operating on
individual files. It was later extended to allow patching eMMC targets
as a whole, in favor of block-based updates.
As we have deprecated file-based OTA since Oreo, part of the code in
applypatch() has become obsolete. This CL refactors the related
functions, by removing the obsolete logic and focusing on eMMC targets.
Since this CL substantially changes applypatch APIs, it adds new
functions to avoid unintentionally mixing them together. In particular,
it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`,
and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()`
and `CheckPartition()`. It also replaces the old Edify functions
`apply_patch()` and `apply_patch_check()` with `patch_partition()` and
`patch_partition_check()` respectively.
This CL requires matching changes to OTA generation script (in the same
topic).

This relands the previously reverted CL in commit
c70446ce7b ("Build and use minadbd as a
shared library."). `recovery` has been built with Soong, so the previous
concern (unintentionally installing `libminadbd_services.so` to normal
system image) no longer holds.
Note that `reocvery` can't use `libminadbd_services.a`, as functions
like `daemon_service_to_fd()` (needed by `libadbd.so`) won't be linked
into `recovery`.
This CL moves the dependency of `libminadbd_services` from `librecovery`
into `recovery`, as only the latter actually relies on it (via
`recovery_main.cpp`). Note that we no longer need to list the transitive
dependency on `libadbd` or `libasyncio`.

The reverted CL has a side effect that unintentionally installs
a copy of libminadbd_services.so to the system image. This breaks the
check with `build/soong/build_test.bash --dist` which detects and
prevents vendor modules from installing files to the system image.
Prior to fully converting `recovery` to be built with Soong, we have to
statically link recovery-specific modules into `recovery`.

The former `minadbd` module is now built as a shared library
(`libminadbd_services.so`) that serves sideloading under recovery, with
a dynamic dependency on `libadbd.so`.
This allows sharing and reusing libadbd code on device (both of `adbd`
and `recovery` now uses `libadbd.so`). As a result, it reduces the size
of `recovery` binary from 1407360-byte to (1272880 + 33032)-byte
(aosp_marlin-userdebug).

We used to statically link the device-specific recovery UI extension
(`TARGET_RECOVERY_UI_LIB`) into `recovery`. Such a logic can't be easily
migrated to Soong, as modules specified by `TARGET_RECOVERY_UI_LIB` may
not be built with Soong.
Instead of porting all the device-specific codes over, this CL builds
and installs the UI lib as a shared library with Android.mk. `recovery`
dlopen(3)'s and dlsym(3)'s `make_device` to invoke the device-specific
UI lib on start.
Note that in order to make dlopen(3) actually working, we have to switch
`recovery` to be dynamically linked (we will make the move later
anyway).

This applies to the standalone applypatch executable
(/system/bin/applypatch on device). This executable is only used when
installing (via patching or flashing) a recovery image on non-A/B
device.
This CL removes the support for patching non-eMMC targets from
applypatch that has been deprecated as part of file-based OTA. For
patching eMMC targets, it also drops the support for accepting multiple
patches (not useful, since the source file must be fixed).
This CL needs the matching change in the same topic, which writes the
script of "/system/bin/install-recovery.sh". Note that this CL doesn't
chanage the applypatch API signatures, in order to minimize the CL size.

The getopt_long(3) implementation in Android (upstream freebsd) expects
a null-terminated array while parsing long options with required args.
if (long_options[match].has_arg == required_argument) {
optarg = nargv[optind++];
}
...
if (long_options[match].has_arg == required_argument && optarg == NULL) {
return (BADARG);
}
This seems to make sense in practice, as getopt(3) takes the first two
arguments of argc and argv that are "as passed to the main() function on
program invocation", and both of C and C++ spec say "the value of
argv[argc] shall be 0".
Prior to the CL, we may run into undefined behavior on malformed input
command line (e.g. missing arg for an option that requires one). This CL
fixes the issue by always appending a nullptr to the argument list (but
without counting that into argc).

Also fix an error-pone behavior in previous code when verifying an eMMC
target. As long as it loads the partition content successfully according
to the SHAs embedded in the filename, it shouldn't further check against
the SHAs given in the second argument. Because the loaded contents
relate to a specific partition size.
For example:
apply_patch_check(
"EMMC:/boot.img:src_size:src_hash:tgt_size:tgt_hash",
"src_hash");
Assume "/boot.img" already has the desired hash of "tgt_hash", the
previous code would give wrong verification result. The issue can be
addressed by additionally listing "tgt_hash" as one of the desired SHAs
(or by applying this CL).

This is a stress test that instantiates multiple testcases that
interrupt a BBOTA update at every transfer command. Each testcase
asserts the last_command_file after the interruption, verifies the
update resumability, then resumes the update and asserts the updated
image.
The transfer list in the testcase covers most of the transfer commands
(stash/free/move/bsdiff/zero/new), as well as some special pattern like
having duplicate stash ids.
This CL also addresses one issue in the updater code, by resetting the
stash_map before each run. The stash map should be valid only per
