David Anderson 0d4277d7b3 fastbootd: Add commands for logical partitions. 
This patch adds the following new commands to fastbootd:

    getvar is_logical:<partition>
    create-logical-logical-partition <partition> <size>
    delete-logical-partition <partition>
    resize-logicallogical-partition <partition> <size>

All of these commands operate on logical partitions only, and require a
properly configured "super" partition to operate.

Bug: 78793464
Test: fastboot create-logical-partition example 4096
      fastboot create-logical-partition example 4096 returns error
      fastboot getvar is-logical:example returns "yes"
      fastboot getvar partition-size:example returns "1000"
      fastboot resize-logicalpartition example 8000
      fastboot getvar partition-size:example returns "2000"
      fastboot delete-logical-partition example
      fastboot getvar is-logical:example returns error
      fastboot getvar is-logical:system_a returns "no"

David Anderson 88ef0b1f25 fastbootd: Add support for flashing logical partitions. 
When flashing logical partitions, we read the "super" partition metadata
corresponding to the current slot. We then temporarily create a
device-mapper device for that partition, and immediately destroy the
device after all operations are complete. We do not mount partitions
ahead of time, or keep them mounted, because a fastboot operation may
change the layout of the logical partition table (or change which slot
is current).

Bug: 78793464
Test: fastboot flash a logical partition under "super"

David Anderson 12211d163e fastbootd: Enable erase and flash commands for physical partitions.

Tao Bao b71eedf912 fastboot: `fastbootd` uses `libadbd.so`. 
The size of `fastbootd` goes down from 64088-byte to 38488-byte
(aosp_taimen-userdebug) after the change.

Bug: 78793464
Test: `m -j installclean && m -j fastbootd`. Check that
      $OUT/recovery/root/system/lib64/libadbd.so exists and
      $OUT/recovery/root/system/bin/fastbootd depends on that.

Hridya Valsaraju 31d2c26409 fastbootd: Implement the getvar command. 
This implements basic "fastboot getvar" support, including commands supported
by IBootControl.

Bug: 78793464
Test: fastboot getvar <fastboot variable>

Hridya Valsaraju dea91b4b53 Add fastbootd. 
Fastbootd is started by recovery, and communicates
over usb with the fastboot protocol.

Add additional fastboot commands to move in and out of
fastbootd. "fastboot reboot recovery" and "fastboot reboot fastboot"

Bug: 78793464
Test: fastboot reboot recovery, fastboot reboot fastboot

Aaron Wisner db511207ed Refactor libfastboot 
This change creates a nice and clean API for issuing
fastboot commands without using the fastboot tool itself.

Test: fastboot tool itself (now using libfastboot2)
on sailfish, walleye, and other devices.
Test: flash bootloader bootloader.img
Test: flash radio radio.img
Test: -w update img.zip
Test: Manually getvar and reboot commands.
