3ffed21262 Remove request for read access to partitions.
It is not needed for flash or erase.

4758967bf9 fastbootd: Fix partition size testing issues.
Partition sizes must be reported with an "0x" prefix for fuzzy_fastboot.
Also, with dynamic partitions, the size of a partition can be 0.

Bug: 78793464
Test: fuzzy_fastboot Conformance.PartitionInfo does not error on
      partition sizes when using fastbootd

0f6266305e fastbootd: Implement getvar all.
This implements getvar all by invoking each callback and writing an INFO
status for each result. For commands that take arguments, the variable
handler can specify a function that returns all possible arguments.
Currently this only applies to partition variables.

Test: fastboot getvar all works

1fb3fd7242 fastbootd: Refactor for getvar all.
It is easier to implement getvar all if we can invoke each variable
handler and collect their results. This change reverts the handlers to
return their messages as an outparam, rather than going through
FastbootDevice.

38b3c7a122 fastbootd: Add an update-super command to sync the super partition.
This change introduces an "update-super" command to the fastboot
protocol. Unlike the "flash" command, which copies raw or sparse data to
a partition, the "update-super" command requires the data to be a super
image generated by lpmake.

If the super partition is not yet formatted (or is corrupt), then it
will be formatted using the given image. Otherwise, "update-super" will
preserve the existing partition layout, and only ensure that logical
partition entries exist for all the new partitions in the given image.
All new partitions added this way will have a zero size, and it is the
host's responsibility to size them as needed afterwards with the
"resize-logical-partition" command.

In addition, the "update-super" command supports a "wipe" argument,
which will force the super partition to be reformatted with the given
image, overwriting any existing partition tables.

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).

Test: fastboot flash a logical partition under "super"

856b7ecbb6 fastbootd: Allow returning errors from getvar handlers.
Currently a few getvar handlers will return invalid strings when an
error occurs. This change allows those handlers to instead send a proper
failure message.

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
