This patch adds a new variable, "super-partition-name", to query the
name of the super partition (with a slot suffix if it has one). The
fastboot flashing tool has been updated to query this variable.
Since the super partition name can no longer be determined without
fastbootd, the presence of super_empty.img is used to test for
dynamic partition support rather than the presence of a super partition.

Without this, it is much more difficult to ensure that the "a" and "b"
slots are both bootable during development. We already update all
metadata slots for update-super, so we should here as well.

Boot control HAL implementations will return the current boot
slot as the active slot. If a set_active command is issued on another
slot, it should be considered as the new active slot and subsequent
flashes should flash the same.

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.

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.

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.

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"
