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).

Normally calling a UI method will block

the UI, causing waitKey to return -2. This
in turn, will cause ShowMenu to return -2.

Bug: 78793464
Change-Id: I4c6c9aa18d79070877841a5c9818acf723fa6096
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).
Test: Build and boot into recovery with commands.

TemporaryDir only deletes empty dirs (not done by its dtor because it

Prior to this CL, FreeSpaceForFile() was returning `size_t`, which may
overflow on ILP32 when called on a partition with 4GiB+ free space.
Additionally, it was returning static_cast<size_t>(-1) on error, but the
caller in freecache.cpp didn't check for that.
This CL changes its return type to `int64_t`, and moves the function
into freecache.cpp since there's no external caller.
Test: Run recovery_unit_test on marlin.
Test: Code search shows no external user of FreeSpaceForFile().

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).

It addresses the ScreenRecoveryUITest failures on gce targets which
don't have any graphics backend. Probing for all backend devices in
tests could work, but would duplicate codes. This CL relies on the
result of gr_init().
As a side effect, it may give false negatives if gr_init() is supposed
to work but silently broken. But such issues are beyond
ScreenRecoveryUITest's concern, which should be captured by the tests
for minui or graphics backends instead.

In order to support that, this CL adds Paths::set_resource_dir() to
override the default resource dir ("/res/images/") that's only available

of requiring the dependency on libotautil for everyone.

Prior to this CL, the block verification works were assigned based on
the pattern of the ranges, which could lead to unbalanced workloads. This
CL adds RangeSet::Split() and moves update_verifier over.

We used to CHECK and abort on parsing errors. While it works fine for
the updater use case (because recovery starts updater in a forked
process and collects the process exit code), it's difficult for other
clients to use RangeSet as a library (e.g. update_verifier).
This CL switches the aborts to returning empty RangeSet instead. Callers
need to check the parsing results explicitly.
The CL also separates RangeSet::PushBack() into a function, and moves
SortedRangeSet::Clear() into RangeSet.

- Uses std::vector<Range> to represent a RangeSet;

In RangeSet::Parse() (the former parse_range()), use libbase logging to
do assertions. This has the same effect as the previous
exit(EXIT_FAILURE) to terminate the updater process and abort an update.
The difference lies in the exit status code (i.e. WEXITSTATUS(status) in
