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.

A global std::string, even if not used, pollutes the bss section
unnecessarily. Since this object is only there for testing, make it
std::optional<std::string>, which is constexpr constructible.
Bug: 138856262
Test: Along with a fix in fs_mgr, see that the bss section for
libbootloader_message.so is now clean on cuttlefish for several
processes.

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`).

Also add libfstab dependencies where needed. Previously the
`typedef struct FstabEntry Volume;` line served to both define a
`struct FstabEntry` as well as alias Volume to it. With the new
namespace for android::fs_mgr::FstabEntry, `struct FstabEntry` isn't
compatible anymore, so we need to alias Volume to the real
android::fs_mgr::FstabEntry.
In doing so, we need to include <fstab/fstab.h> and this requires
libfstab as a library, which a few modules did not have before.

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.

Test: normal boot sailfish, go to Settings > System & tap

Test: recovery boot sailfish
libbootloader_message is used by both normal boot and recovery boot.
It needs to use different fstab paths, respectively. Otherwise, factory
reset will fail when we move /fstab.{ro.hardware} to /vendor/etc/.

The fstab settings of early-mounted partitions (e.g., /vendor) will be in
kernel device tree. Switch to the new API to get the whole settings with
those in device tree:
fs_mgr_read_fstab_with_dt("/etc/recovery.fstab")
The original default /fstab.{ro.hardware} might be moved to
/vendor/etc/. or /odm/etc/. Use another new API to get the default fstab
instead of using the hard-coded /fstab.{ro.hardware}. This API also
includes the settings from device tree:
fs_mgr_read_fstab_default()

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.
