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).

Now it's less beneficial to inject I/O faults since we don't see many of
them. Remove the library that mocks I/O failures. And switch to android::base
I/O when possible.

Also separate libupdater_defaults out to be shareable.
It turns out the `data` property in `cc_test` doesn't follow symlinks as
LOCAL_TEST_DATA does in Android.mk. This CL creates a filegroup in
top-level Android.bp in order to pick up the testdata for ResourcesTest.

The new command is part of the transfer.list and allows us to compute the hash
tree on non-ab devices.
The required arguments for the hash_tree computation are:
hash_tree_ranges
source_ranges
hash_algorithm
salt_hex
root_hash

They are doing exactly the same thing, except for the slightly different
error return value (1 vs -1).
int CacheSizeCheck(size_t bytes);
int MakeFreeSpaceOnCache(size_t bytes_needed);
This CL consolidates the two functions and uses bool as its return type.
// Checks whether /cache partition has at least 'bytes'-byte free space. Returns true immediately
// if so. Otherwise, it will try to free some space by removing older logs, checks again and
// returns the checking result.
bool CheckAndFreeSpaceOnCache(size_t bytes);

It used to return a Value blob to be consumed by sha1_check() (which has
been deprecated). Currently there's no other generic updater function
that works with BLOB Values. This CL changes read_file() to return a
string Value to make it more useful (e.g. allowing equality check).

The matching edify function has been removed from EdifyGenerator [1]. In
theory device-specific releasetools script may still use this function,
but it no longer looks useful. Because a) we should use range_sha1()
when asserting the SHA-1 hash of a block device; b) we should look into
the contents when asserting a text file.

This will be used for testing purpose only, replacing the previously
used "fail", to intentionally abort an update.
As we're separating the logic between commands parsing and execution,
"abort" needs to be considered as a valid command during the parsing.

During block verification, load stash reads from the source blocks on
the device instead of the stashed files. And for interrupted update,
it's pretty common that the source blocks has already been overwritten
by subsequent commands.
In that case the hash printing is mostly useless. Moreover we should have
already printed the hash when the first update failed.

Test: Unit tests pass. No longer prints mismatching stashed source blocks on retry.

The two utilities are now converted to dynamic executables as shared

This avoids leaving the created new data writer thread unjoined, in the
presence of transfer list parsing errors, or the early exit case on
`total_blocks == 0`.
Also fix a minor issue when dumping the errno on pthread_create error
(pthread_create returns the error number, as opposed to setting errno).

As suggested by the style guide
(https://google.github.io/styleguide/cppguide.html#Reference_Arguments),
all parameters passed by reference must be labeled const. This CL moves
most of the non-const references in blockimg.cpp to pointers, except for
the CommandParameters& parameter in PerformCommand* functions, which
will be handled in separate CLs.

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
block_image_verify/block_image_update run. Having leftover may cause
issue in subsequent runs, in particular when calling block_image_verify
after a previous run of block_image_{update,verify}.
