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.

Test: Unittest passed, apply a failed update with invalid cmd on angler
and check the last_command content, apply a failed update with invalid
source hash and last_command is deleted.

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().
Test: Message from ErrorAbort shows up in the log

The update_channel field is used to store the Omaha update channel
if update_engine is compiled with Omaha support.
We need it to be in misc to persist through factory reset.

Make update_verifier check if it runs on A/B update devices at the
beginning, and quit immediately if it doesn't, instead of re-boot.

It used to keep track of the stat(2) info (e.g. st_mode/st_gid/st_uid)
while patching a file in file-based OTA.
Test: Build and use the new updater to apply an update on bullhead.

An interrupted update may stash extra blocks in /cache, leading to a
failure when checking the cache size. We can save the incremented
retry_count in the BCB before installing the update; and distinguish
a fresh update from an interrupted one this way.
Bug: 68679601
Test: An interrupted update reapplies successfully.

fs_mgr passes negative length as offset for crypt_footer. We need
to compute the actual device size for this case in addition to
when length is zero.
