e94b64ae86 bootloader_message: Remove global std::string
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.

7ae0169842 Add misc_writer.
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

Bug: 132906936
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`).

72a114a3e1 Add android::fs_mgr namespace for new Fstab code
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.

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

fb00d82f32 Boot control HAL based on the A/B headers.
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.

4508f23884 Revert "libbootloader_message: use different fstab paths for normal/recovery boot"
This reverts commit 37bd44174b.

The logic here is better to be moved into fs_mgr, not fs_mgr clients.

37bd44174b libbootloader_message: use different fstab paths for normal/recovery boot
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/.

  Recovery boot: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab")
  Normal boot: fs_mgr_read_fstab_default()

d13b6cf29c recovery: replacing fs_mgr_read_fstab() with new fs_mgr APIs
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()

2292db819b Add update_bootloader_message() to fix two-step OTAs.
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.

manage bootloader_message in normal boot and recovery mode.
