(cherry picked from commit ac31808cd3)
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

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

Currently the ui_print command between the recovery and updater doesn't
append newline. Updater has to send an extra "ui_print" command without
any argument to get the line break. This looks unnecessary. And not all
the callers (including the ones in bootable/recovery) are following this
protocol when sending the ui_print command.
This CL simplifies the protocol to always print with a newline for
ui_print command. When updating from an old recovery with the new
updater, all the ui_print'd strings would appear in one line as a side
effect. But a) it would only affect the text-mode UI, which won't be
shown to users; b) log files won't be affected.

Remove O_SYNC from mzExtractRecursive() and PackageExtractFileFn().
These functions deal with extracting whole files from the update
package onto a filesystem. If run on ext4 on a rotating disk, for
example, the O_SYNC flag will cause serious performance problems
and the extraction proecss can take over 30 minutes, with no
obvious benefits.
This API function already calls fsync(fd) after each file is
extracted to ensure data and metadata is written to the underlying
block device, so the O_SYNC calls should be superfluous and safely
removable.
This change does not affect the OTA patch paths or any modification
of the bootloader partition or writes to other 'emmc' partitions.

[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.

If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same
library, there would be linking errors when generating a shared library
(or executable) that depends on the two libraries both.
Also clean up Android.mk files.
Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The
module will then default to "optional" which won't be built until needed.

Change-Id: I4dd44417d07dd0a31729894628635a0aa1659008
Add block_image_recover function to rewrite corrupted blocks on the
partition. This can be attempted if block_image_verify fails.
Note that we cannot use libfec during block_image_update as it may
overwrite blocks required for error correction. A separate recovery
pass in case the image is corrupted is the only viable option.

A RangeSet has half-closed half-open bounds. For example, "3,5" contains
blocks 3 and 4. So "3,5" and "5,7" are actually not overlapped.

Although stdout and stderr are both redirected to log file with no
buffering, we are seeing some outputs are mixed in random order.
This is because ui_print commands from the updater are passed to the
recovery binary via a pipe, which may interleave with other outputs
that go to stderr directly.
In recovery, adding ui::PrintOnScreenOnly() function to handle
ui_print command, which skips printing to stdout. Meanwhile, updater
prints the contents to stderr in addition to piping them to recovery.

In the block updater, if BLKDISCARD fails, the error is silently
ignored and some of the blocks may not be erased. This means the
target partition will have inconsistent contents.
If the ioctl fails, return an error and abort the update.

When automatically stashing overlapping blocks, should the stash
file already exist due to an explicit stash command, it's not safe
to remove the stash file after the command has completed.
Note that it is safe to assume that the stash file will remain in
place during the execution of the next command, so we don't have
take other measures to preserve overlapping blocks.
The stash file itself will be removed by a free command when it's
no longer needed.

Add support for transfer list version 3, which allows us to
verify the status of each command and resume an interrupted
block based OTA update. Notes on the changes:
- Move the previous BlockImageUpdateFn to a shorter and
reusable PerformBlockImageUpdate, which can be used also
in BlockImageVerifyFn for verification.
- Split individual transfer list commands into separate
functions with unified parameters for clarity, and use
a hash table to locate them during execution.
- Move common block reading and writing to ReadBlocks and
WriteBlocks to reduce code duplication, and rename the
readblock and writeblock to less confusing read_all and
write_all.
The coding style of the new functions follows the existing
style in the updater/edify code.

When building for 32p, we need to be explicit that we wish to build
the 32bit version of the binaries that will be placed in the recovery
image. The recovery image doesn't actually care... but if we are not
explicit in this, the makefiles will ask for the 64bit binaries but the
Android.mk for the binaries will supply the 32bit images (causing the
build to fail).
