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}.
Test: Run recovery_component_test on marlin.

Move the commands map parsing out of PerformBlockImageUpdate(), as this
can be done more easily by the caller.
The goal (not done in this CL) is to decouple command parsing logic from
the performers. This allows (a) focusing on the command logic in the
performer; and (b) extending BBOTA commands syntax separately.
Test: Run recovery_unit_test and recovery_component_test.

The last command file has the last executed stash command by convention.
So we should update the file after we actually finishes executing the command;
instead of after loading src/tgt.

We cannot skip "new" commands while resuming an update with
last_command_file, because they read in the data sequentially from the
package.

Test: Interrupt an update that has new commands. Check the update log.

Prior to the change, the BBOTA updater would try to re-run all the
commands for a given partition on retry, including creating stashes
according to the list of commands. This could fail a retry when the
previous update had moved on to next stage, with leftovers in /cache.
This CL creates a marker on /cache upon successfully updating a
partition. The update commands will be skipped when trying to apply
updates on an updated partition. Note that the marker is expected to be
removed while doing a normal boot (in particular, handled by
RecoverySystem#handleAftermath). If that didn't happen, the updater
would also remove the marker before starting next fresh update.
Alternatively, we can achieve the same goal by changing the OTA script,
which needs to additionally compare the checksum against the target
build. For example,
range_sha1("/system", "ranges") == SHA1_of_updated_system ||
block_image_update("/system");
The downside is that we need to pay that cost on each install, as the
edify script doesn't support caching the result in a variable.

This breaks the dependency on common.h (which belongs to
recovery/librecovery) from librecovery_ui. reboot() is now owned by
libotautil, which is expected to be a leaf node to be depended on.
With the change, recovery and updater also share the same reboot() code
now.

This class allows us to set the following locations dynamically:
cache_temp_source, last_command_file, stash_directory_base.
In the updater's main function, we reset the values of these variables
to their default locations in /cache; while we can set them to temp
files in unit tests or host simulation.
Test: unit tests pass

In BlockImageVerify some commands are undefined, e.g. "erase", "new",
"zero". And we should not error out if the corresponding function
pointer of these commands is null; otherwise we will fail the
verification.
The old code is:
if (cmd->f != nullptr && cmd->f(params) == -1)
return false;
In the last_command_file change the logic was wrongly modified to
if (cmd->f == nullptr)
return false;
...
if (cmd->f(params) == -1)
return false;

When performing an update, save the index and cmdline of the current
command into the last command file if this command writes to the stash
either explicitly of implicitly. This mitigates the overhead to update
the last command file for every command. I ran a simple test on angler
and the time to update 1000 times is ~2.3 seconds.
Upon resuming an update, read the saved index first; then
1. In verification mode, check if all commands before the saved index
have already produced the expected target blocks. If not, delete the
last command file so that we will later resume the update from the
start of the transfer list.
2. In update mode, skip all commands before the saved index. Therefore,
we can avoid deleting stashes with duplicate id unintentionally;
and also speed up the update.
If an update succeeds or is unresumable, delete the last command file.
Bug: 69858743
Test: Unittest passed, apply a failed update with invalid cmd on angler
and check the last_command content, apply a failed update with invalid

The AbortFn() used to overwrite the error message, hiding the real
failure reported in ErrorAbort(). And we will miss the failure in
the script patterns like 'blockimageupdate() || abort()'
We will ensure there's one line break at the end of ErrorAbort's
error message; and append to the existing error message when calling
abort().

An interrupted update may stash extra blocks in /cache, leading to a
failure when checking the cache size. We can save the incremented

a fresh update from an interrupted one this way.
