f8811bbd3a updater: Add TransferList class.
This would be the top-level class that represents and holds the info
parsed from a transfer list file.

Bug: 112151972
Test: Run recovery_unit_test and recovery_component_test on marlin.

8f64bf635f Add the hash_tree_info class in Command
Add hash_tree_info to represent the hash tree computation arguments in
the transfer commands 'compute_hash_tree'. Also add its parsing code in
the Command class.

Test: unit tests pass

69ffa15338 Add an updater function to compute hash tree
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

Bug: 25170618
Test: unit tests pass;  run simulator with compute_hash_tree

91a649ab62 updater: Add ABORT command.
This will be used for testing purpose only, replacing the previously
used "fail", to intentionally abort an update.

As we're separating the logic between commands parsing and execution,
"abort" needs to be considered as a valid command during the parsing.

Test: recovery_unit_test and recovery_component_test on marlin.

6a7e4af7c6 updater: Add Command parsing codes.
The added codes are not used in the updater yet. The switch will happen
in subsequent CLs.

Test: Run recovery_unit_test and recovery_component_test on marlin.

c3901231ce updater: Add Commmand class to manage BBOTA commands.
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.

3bbb20f557 Add a singleton CacheLocation to replace the hard coded locations
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

284752e2bc Log the last command to cache
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
source hash and last_command is deleted.

57dd961995 Move Image/ImageChunk/PatchChunk declaration into header files
1. Move the declaration of the Image classes to the header file to make
testing easier.
2. Also move rangeset.h to bootable/recovery to allow access in imgdiff.

Test: recovery component test

bf5b77dbf7 Change the internal representation in RangeSet.
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').

Test: recovery_unit_test
Test: Apply an incremental update with the new updater.

8f23757ad4 Move parse_range() and range_overlaps() into RangeSet.
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.

Test: recovery_unit_test
Test: Apply an incremental update with the new updater.

8cf5c8f60f Replace minzip with libziparchive
Clean up the duplicated codes that handle the zip files in
bootable/recovery; and rename the library of the remaining
utility functions to libotautil.

Test: Update package installed successfully on angler.

0c7839ac14 Refactor libupdater into a seperate module.
So that we can write native tests for updater functions. This CL adds a
testcase for getprop() function.

Test: mmma bootable/recovery; Run recovery_component_test on device.
