receive_new_data may exit too early if the zip processor has sent all
the raw data. As a result, the last few 'new' commands will fail even
though the brotli decoder has more output in its buffer.
Restruct the code so that 'NewThreadInfo' owns the decoder state solely;
and receive_brotli_new_data is responsible for the decompression.
Also reduce the test data size to 100 blocks to avoid the test timeout.

Test: recovery_component_test. on bullhead, apply full updates with and

Add a new writer that can decode the brotli-compressed system/vendor
new data stored in the OTA zip.
Brotli generally gives better compression rate at the cost of slightly
increased time consumption. The patch.dat is already compressed
by BZ; so there's no point to further compress it.
For the given 1.9G bullhead system image:
Size: 875M -> 787M; ~10% reduction of package size.
Time: 147s -> 153s; ~4% increase of the block_image_update execution time.
(I guess I/O takes much longer time than decompression.)
Also it takes 4 minutes to compress the system image on my local
machine, 3 more minutes than zip.
Test: recovery tests pass && apply a full OTA with brotli compressed
system/vendor.new.dat on bullhead

We have seen one case when bspatch failed likely due to patch
corruption. Since the package has passed verification before, we want
to reboot and retry the patch command again since there's no
alternative for users.
We won't delete the stash before reboot, and the src has passed SHA1
check. If there's an error on the patch, it will fail the package
verification during retry.

Test: angler reboots and retries the update when bspatch fails.

This CL makes the following changes to RangeSet:
- Uses std::pair<size_t, size_t> to represent a Range;
- Uses std::vector<Range> to represent a RangeSet;
- Provides const iterators (forward and reverse);
- Provides const accessor;
- 'blocks()' returns the number of blocks (formerly 'size');
- 'size()' returns the number of Range's (formerly 'count').

Also move RangeSet into a header file to make it testable, and add unit
tests.
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
install.cpp), which changes from 1 (i.e. EXIT_FAILURE) to 0.

Mostly for applypatch family APIs like ApplyBSDiffPatch() and
ApplyImagePatch(). Changing to size_t doesn't indicate they would
necessarily work with very large size_t (e.g. > ssize_t), just
similar to write(2). But otherwise accepting negative length doesn't
make much sense.
Also change the return type of SinkFn from ssize_t to size_t. Callers
tell a successful sink by comparing the number of written bytes against
the desired value. Negative return values like -1 are not needed. This
also makes it consistent with bsdiff::bspatch interface.

Rename to LoadSourceBlocks() by moving the target blocks parsing part
into the caller. This allows detecting whether the target blocks have
already had the expected data before loading the source blocks. It
doesn't affect anything when applying an update package for the first
time, but it skips loading the unneeded source blocks when resuming an
update. It additionally avoids unnecessarily dumping the "corrupt"
source/stash blocks when resuming an update.

Our updater created the stashes with root permission. This causes an
access denial when the RecoverySystem service tries to clean up these

It will be helpful for debug if we know which blocks are corrupted after
a verification failure. This CL prints the SHA-1 for each source block
in a transfer command if these blocks don't have an expected hash. And

[1] switched a few things to android::base::unique_fd including
CommandParameters.fd. However, we were using memset(3) to zero out the
struct, which effectively assigned unique_fd(0) to fd. When it called
fd.reset(), file descriptor 0 was unintentionally closed. When FD 0 was
later reassigned via open(2), it led to lseek(2) errors: "Bad file
descriptor".
This CL switches to using braced-init (i.e. '= {}') instead, so that the
default constructor unique_fd(-1) would be called.
