This change addresses the comment in [1], which makes the results of
`adb shell getprop foo` and `adb rescue getprop foo` more consistent.
That is, both will return newline-terminated results now.

Test: Run the following commands on taimen (under rescue mode):
`adb rescue getprop ro.build.fingerprint`
`adb rescue getprop ro.nonexistent`
`adb rescue getprop`

It dumps all the allowed properties, similar to `adb shell getprop`.

Test: Run the command under rescue mode.

Most of these properties are already part of the fingerprint. This CL
allows querying them directly, instead of encouraging users to decode
from fingerprints.
Bug: 134027350
Test: Boot into rescue mode on taimen. Run `adb rescue getprop` with new
props.

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`).

bootloader will set `boot-rescue` in BCB command field to indicate
booting into rescue mode. This CL adds the matching parsing code.
This CL changes the on-screen UI to display the default image while
waiting for each sideload / rescue command.
It also changes the minadbd reboot handlers to use REBOOT_ instead of
the previous ENTER_ actions. This ensures a reboot going through
bootloader, which may load a newly installed bootloader/recovery.

Test: Boot into rescue mode. Run `adb rescue getprop` and `adb rescue
install`. Check the UI. Then run `adb reboot rescue`.

Ass some unit tests to check if the minadbd service exit correctly in
the failure case. Also start the fuse and verify the socket communication
between minadbd with adb host, and minadbd with recovery.
Bug: 131037235
Test: run unit tests repeatedly, injects some errors and test fails
without dangling process.

This leaves the FD implementation details to subclasses. In particular,
it allows minadbd to do additional works with the FD after sideloading.

We perform these steps to perserve the recovery logs when wiping
/cache partition. Move them to logging.cpp to keep the actually
EraseVolume function concise.
Bug: 130166585
Test: unit tests pass, mount cache and check last log after cache

Therefore, libinstall becomes the sole owner to handle the request
from minadbd service.
The change also includes
1. move logging.cpp out of librecovery
2. drop the dependency on common.h
3. now it's more sensible to move the wipe_cache as part of
install_package. move the wipe_cache to the end of the function.

Test: wipe data and cache from menu

(cherry picked from commit 316e971746)
This cl adds a socket pair to support the communication between recovery
and minadbd. Therefore, minadbd will be able to issue multiple commands
to recovery and get back the status of each command.
This cl also switches the adb sideload from the recovery menu to use
this protocol; and moves minadbd to a separate binary.
Bug: 130166585
Test: sideload a package

(cherry picked from commit 34690ced91)
It was once considered to be shared between recovery and minadbd, so
that the latter can start an install on its own. The plan has been
changed, since package install -- including device wipe operations --
could be device-specific, which should be done by recovery only.
This CL moves libinstall back to a static library, which also saves the
overall size (reducing from 140256 + 660576 to 555880 bytes on
aosp_taimen-userdebug).
Bug: 130166585
Test: Run recovery_component_test.
Test: `adb sideload` on taimen.

This used to be a helper function that allows printing message to UI.
We no longer have any active user in bootable/recovery. Device-specific
code can achieve the same functionality by calling GetUI()->Print()
instead.
Test: mmma -j bootable/recovery

Build libinstall as a shared library. Also drop the dependency on the
global variables in common.h.
Test: unit tests pass, sideload an OTA

If we use the default parameter we'll get O_CLOEXEC, which will close the fd
that we pass to the child process, which will cause it to fail. Passing zero
avoids the problem.
Bug: 122813742
Test: Verify that non-A/B OTA update is successful.
