Bug: 78793464
Test: fastboot flashall
Sparse images with CRC are not supported by the Android build
system and hence the calculated CRC is unused.

If a device has logical partitions but does not use a partition called
"super", we will need this to be configurable. Note that the "slot"
argument is currently unused, but will be necessary for update_engine if
there are A and B super partitions.

Test: super partition works

Note that in addition to waiting for the path to appear, we must also
wait for it to be unlinked. Otherwise, we could accidentally access an
older device when opening and closing the same partition twice in a row.

Partition sizes must be reported with an "0x" prefix for fuzzy_fastboot.
Also, with dynamic partitions, the size of a partition can be 0.

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

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

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.

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.

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"

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.

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
