It should belong to the default /misc implementation of boot control
1.1. Right now, it's only used by cuttlefish. So move it over to reduce
confusion in bootloader_message.

This adds a sanity check in addition to the version number in case misc
contains random bits.

The layout of the vendor space /misc partition was pretty confusing and
lead to some usage conflicts. To formalize the layout, we create a pixel
specific library with the definition & offset of various flags. The new
library also handles the R/W. As a result, we will leave system domain
/misc definitions in the libbootloader_message.
We also switch the misc_writer binary to use more specific options
instead of writing an arbitrary hex string. So we can avoid redefining
the string & offset in both init script and recovery ui.
Bug: 131775112
Test: unit tests pass, run misc_writer and check contents of /misc

Move merge_status from bootloader_control_ab, which is in vendor space,
to a new generic AOSP struct in system space. This will allow more
devices to share the same HAL implementation.
This patch also changes libboot_control to compensate for merge_status
moving out of vendor space. The reference HAL library now also provides
separate helper functions for managing the merge status, so devices
using a custom boot control HAL can still take advantage of the new misc
implementation.

This reduces the wipe space from 32K to 16K. The wipe space is now
at the 16K-32K region. The 32K-64K region is now "system space", to
complement the vendor space, for generic AOSP usage.

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`).

The update_channel field is used to store the Omaha update channel
if update_engine is compiled with Omaha support.
We need it to be in misc to persist through factory reset.

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.

The added bootctrl.bcb module implement the legacy interface for the
bootctrl HAL based on the Boot Control Block (BCB) and the headers
already specified in the booloader_message library.
This serves as a reference implementation of the boot_control HAL.
Bug: 32707546
Test: Tested internally that a device can use this HAL to flip slots and
recovery from a /misc wipe.

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.

Add read_bootloader_message_from() and write_bootloader_message_to() to
allow specifying the BCB device (/misc).
Also add testcases for set_stage() and get_stage().
Test: recovery_component_test passes.
Test: Build a recovery image and apply a two-step OTA package.

bootloader_messages merges bootloader_message_writer
and bootloader.cpp, so we can use the same library to
manage bootloader_message in normal boot and recovery mode.
