bootloader_message.h currently divides /misc into four segments. The
space between 2K and 16K is reserved for vendor use (e.g. bootloader
persists flags). This CL adds a vendor tool "misc_writer", to allow
writing data to the vendor space in /misc, before getting a dedicated
HAL for accessing /misc partition (b/131775112).
Targets need to explicitly include the module, then invoke the
executable to write data. For example, the following command will write
3-byte data ("0xABCDEF") to offset 4 in vendor space (i.e. 2048 + 4 in
/misc).
$ /vendor/bin/misc_writer --vendor-space-offset 4 --hex-string 0xABCDEF

Test: Run recovery_unit_test on crosshatch.
Test: Call the command via init.hardware.rc on crosshatch. Check that
the call finishes successfully. Then check the contents written to
/misc (`dd bs=1 skip=2048 if=/dev/block/sda2 count=32 | xxd`).

(cherry picked from commit 7ae0169842)
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.

Test: recovery tests pass

Since commit fb00d82f32 has added
get_bootloader_message_blk_device() as an API, switch the tests-local
implementation to it.
Test: recovery_component_test on angler.
Test: recovery_component_test on a local build that doesn't have /misc.

The test should not clear bcb during teardown on devices without
/misc.
Bug: 35712836
Test: The test tears down without errors after /misc removed from the fstab.
Change-Id: I42df89feb18fac5a435cd17eef97a6bad0f44545
Skip these two tests if /misc partition is not found in fstab.
Bug: 35712836
Test: Both test skip correctly if there's no /misc in fstab.${hardware}.

This is a retry of commit 7e31f421a5.
Commit bd56f1590c switches to calling
write_bootloader_message(<options>) in get_args(), which
unintentionally resets the stage field thus breaks two-step OTAs.
This CL adds update_bootloader_message(<options>), which only sets
the command field (to "boot-recovery") and the recovery field (with
the specified options).
Bug: 33534933
Test: Apply a two-step package.
Test: recovery_component_test passes.
