The TargetFile class parses a target-file and provides functions to read
its contents. And the BuildInfo tries to simulate the device with files
on host. Some work it does includes parsing the build properties,
and extracting the image files for partitions specified in the fstab.
Bug: 131911365
Test: unit tests pass, run simulator with cuttlefish, wear devices and from extracted TF.

Disable building the simulator and its support libraries to resolve the breakage

The UpdaterInfo class is merely a collection of pointers and POD types.
We can replace it with a Updater class that has the ownership of the
resources. This also makes this class extensible as we plan to add more
functionality in the host simulator.

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.

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

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.

Turn on -Wall for all modules. Also remove the obsolete file_cmp() in
apply_patch test and now() in wear_ui.
The only exception is lib_edify due to the unused functions in the
intermediate cpp files generated from the lex files. It will be handled
in a seperate CL.

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

Since this was putting the intermediate file in obj/PACKAGING, every
installclean was removing it and triggering updater to rebuild. Instead,
use the standard generated-sources-dir. The dep file can also be removed
now that ninja will re-run the generator if the command line changes.
Test: m -j updater; m installclean; m -j updater
Test: Only change to aosp_fugu updater before/after is the debug info

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.

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.

These are already getting libc++, so it isn't necessary. If any of the

there will be symbol collisions.

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).
