This class adds a wrapper to the runtime dependent functions. Therefore,
the behavior of update on device stays the same, while simulators can
have their own implementations. Also change the caller side of the
registered updater functions to call these runtime wrappers.

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

The results from these functions have boolean semantics. They're
returning `int` prior to this CL, with some of them mixing 0 and
InstallResult. Note that SetUpNonAbUpdateCommands() was returning
INSTALL_CORRUPT / INSTALL_ERROR / 0 prior to this change, but all the
callers handle INSTALL_CORRUPT and INSTALL_ERROR the same way.
This CL changes them to return bool instead.

Most of the tests in component/ are in fact unit tests. And it doesn't
look practically beneficial to distinguish between the two:
- They have the same test setup;
- We always run both (recovery_unit_test and recovery_component_test)
at the same time;
- Breaking any of them would be equally bad.

recovery_unit_test to save the effort to maintain both.

The legacy png files have an empty line in the end. And the recovery

We have already switched to the protobuf format for new builds, and

The two functions check_wipe_package() and check_newer_ab_build() were
using the same flow; and checked the same device properties against the

This CL adds GRSurface::Create() and dtor for managing the allocated
memory in GRSurface class. It also adds GRSurface::data() that hides the
underlying implementation, with both of const and non-const overloads.
This allows `const GRSurface&` to be more useful - previously it only
ensured a const member variable of `data`, instead of a read-only buffer
it points to.
It also marks the parameters in gr_texticon() and gr_blit() as const, as
they're incoming source that shouldn't be altered. It corrects the type
of gr_draw, which is the sink to be painted on (an earlier attempt was
made in [1], but didn't get the full picture correctly).

As we plan to show localized rescue party dialogs under recovery mode
with pre-generated images, it becomes necessary to show the menu headers
and items with images.
This cl converts the menu class to a interface and derived TextMenu &
GraphicMenu classes. And the GraphicMenu uses GRSurfaces* as the menu header
and a list of GRSurfaces* as menu items.
Moreover, factor out the Draw* functions in the ScreenUI into a separate
DrawInterface. Therefore, the Menu class can access these draw functions and
use them to implement the DrawHeaders & DrawItems neatly.

applypatch() was initially designed for file-based OTA, operating on
individual files. It was later extended to allow patching eMMC targets
as a whole, in favor of block-based updates.
As we have deprecated file-based OTA since Oreo, part of the code in
applypatch() has become obsolete. This CL refactors the related
functions, by removing the obsolete logic and focusing on eMMC targets.
Since this CL substantially changes applypatch APIs, it adds new
functions to avoid unintentionally mixing them together. In particular,
it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`,
and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()`
and `CheckPartition()`. It also replaces the old Edify functions
`apply_patch()` and `apply_patch_check()` with `patch_partition()` and
`patch_partition_check()` respectively.

This relands the previously reverted CL in commit
c70446ce7b ("Build and use minadbd as a
shared library."). `recovery` has been built with Soong, so the previous
concern (unintentionally installing `libminadbd_services.so` to normal
system image) no longer holds.
Note that `reocvery` can't use `libminadbd_services.a`, as functions
like `daemon_service_to_fd()` (needed by `libadbd.so`) won't be linked
into `recovery`.
This CL moves the dependency of `libminadbd_services` from `librecovery`
into `recovery`, as only the latter actually relies on it (via
`recovery_main.cpp`). Note that we no longer need to list the transitive
dependency on `libadbd` or `libasyncio`.

The former `minadbd` module is now built as a shared library
(`libminadbd_services.so`) that serves sideloading under recovery, with
a dynamic dependency on `libadbd.so`.
This allows sharing and reusing libadbd code on device (both of `adbd`
and `recovery` now uses `libadbd.so`). As a result, it reduces the size
of `recovery` binary from 1407360-byte to (1272880 + 33032)-byte
(aosp_marlin-userdebug).

We used to statically link the device-specific recovery UI extension
(`TARGET_RECOVERY_UI_LIB`) into `recovery`. Such a logic can't be easily
migrated to Soong, as modules specified by `TARGET_RECOVERY_UI_LIB` may
not be built with Soong.
Instead of porting all the device-specific codes over, this CL builds
and installs the UI lib as a shared library with Android.mk. `recovery`
dlopen(3)'s and dlsym(3)'s `make_device` to invoke the device-specific
UI lib on start.
Note that in order to make dlopen(3) actually working, we have to switch
`recovery` to be dynamically linked (we will make the move later
anyway).

Test: Build and boot into marlin recovery image. Check that
device-specific recovery UI is successfully loaded.

The new command is part of the transfer.list and allows us to compute the hash
tree on non-ab devices.
The required arguments for the hash_tree computation are:
hash_tree_ranges
source_ranges
hash_algorithm
salt_hex
root_hash

Test: unit tests pass; run simulator with compute_hash_tree

Normally calling a UI method will block
indefinitely until the UI is actually
used. This creates a method to interrupt
the UI, causing waitKey to return -2. This
in turn, will cause ShowMenu to return -2.
This allows switching between recovery and
fastbootd via usb commands.
