5ee25666cc applypatch: Consolidate CacheSizeCheck() and MakeFreeSpaceOnCache().
They are doing exactly the same thing, except for the slightly different
error return value (1 vs -1).

int CacheSizeCheck(size_t bytes);
int MakeFreeSpaceOnCache(size_t bytes_needed);

This CL consolidates the two functions and uses bool as its return type.

// Checks whether /cache partition has at least 'bytes'-byte free space. Returns true immediately
// if so. Otherwise, it will try to free some space by removing older logs, checks again and
// returns the checking result.
bool CheckAndFreeSpaceOnCache(size_t bytes);

Test: Run recovery_unit_test and recovery_component_test on marlin.

49750f15ed applypatch: Fix the return type of FreeSpaceForFile().
Prior to this CL, FreeSpaceForFile() was returning `size_t`, which may
overflow on ILP32 when called on a partition with 4GiB+ free space.
Additionally, it was returning static_cast<size_t>(-1) on error, but the
caller in freecache.cpp didn't check for that.

This CL changes its return type to `int64_t`, and moves the function
into freecache.cpp since there's no external caller.

Test: Run recovery_unit_test on marlin.
Test: Code search shows no external user of FreeSpaceForFile().

641fa97def Rename CacheLocation to Paths.
We have a general need for overriding more paths (e.g. "/tmp"), mostly
for testing purpose. Rename CacheLocation to Paths, and use that to
manage TEMPORARY_{INSTALL,LOG}_FILE.

Test: mmma -j bootable/recovery
Test: recovery_component_test

d5fbcc1ba9 Remove the old log files if cache space is insufficient for OTA
We set the limit of the max stash size to 80% of cache size. But the
cache space can still be insufficient for the update if the log files
occupy a large chunk of /cache. So remove the old logs for now to make
room for the update.

Test: unit tests pass

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

e40c80d021 Skip the cache size check on host
When running the update simulation, we choose to skip the cache size
check for now due to the lack of "/cache" on host. And in later cls we
can implement a cache size estimator to make the check more constrained.

Also build the host version of support libraries.

Test: unit test pass

a88cc5440e Switch to bionic gtest in bootable/recovery
We encountered segfaults in Imgdiff host tests due to the failure to
reset states of getopt. The problem can be solved by switching to use
bionic's gtest where a new process is forked for each test.

Also modify the recovery_component_test to make sure it runs in parallel.
Changes include:
  1. Merge the writes to misc partition into one single test.
  2. Change the hard coded location "/cache/saved.file" into a configurable
  variable.

Bug: 67849209
Test: recovery tests pass

d80a99883d Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.
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.
