1d504e3342 fastbootd: Add command to remove GSI installs
Note: this only removes the bootable marker, since we're unable to
remove the userdata files within recovery.

Bug: 121210348
Test: fastboot gsi wipe
      fastboot gsi disable

8956964ee2 fastboot: Warn when flashing dynamic partitions in the bootloader.
On retrofit devices, it is easy to accidentally overwrite
system/vendor/product by flashing system in the bootloader. The reason
is that GPT system_a is really the super partition, and the bootloader
doesn't know it.

Addressing this in bootloaders would require two separate commands: one
that rejects flashing system/vendor/product, and another for
expert/factory use that would allow direct flashing.

This patch introduces protection into the host fastboot tool instead.
It's not mutually exclusive with bootloader changes; having protection
in the host tool affords us better and consistent UI. However it does
rely on users having newer builds.

With this change, the following will not work in the bootloader:

    fastboot flash system       # or vendor, product, etc

The message is the same whether or not the device is a retrofit. To
continue anyway, you can do:

    fastboot flash --force system

If we decide on bootloader protection as well, the --force flag can be
re-used.

Bug: 119689480
Test: fastboot flash system # disallowed in bootloader, allowed in fastbootd
      fastboot flash --force system # allowed in bootloader

9027af0d40 fastboot: remove engine.cpp/engine.h
Replace the remnants of engine.cpp with better functionality in
FastBootDriver.  Particularly, add prolog() and epilog()
callbacks to FastBootDriver for printing actions and their result to
the console.  Then clean up the rest of fastboot.cpp to directly use
FastBootDriver.

Test: fastboot works

822465a930 Fix the mac fastboot build
The Carbon framework isn't on the list of libraries that Soong allows
linking against, so this broke the Mac build. This compiles just fine
without Carbon though, and I don't see any references to Carbon in the
code.

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"

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).

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.
