This change allows partition data to be included in the sparse image for
the super partition. The data is specified as a map from partition name
to partition image file. The image file can either be a normal file or a
sparse image. If it is sparse, it is unpacked into a temporary file and
then re-packed into the super image.

Test: (1) lpmake -S with a partition image flashes to walleye.
(2) The image can be mounted if it contains a filesystem.
(3) simg2img will successfully unpack the image.

liblp currently creates sparse files with a block size of 512 bytes.
Unfortunately devices can reject sparse files that don't have a specific
block size. To accomodate this, SparseBuilder now requires that
partition metadata be built with an explicit block size, and the device
alignment must be a multiple of that block size.
This change also modifies SerializeGeometry to automatically include
0-padding to 4096 bytes.

Callers already verify that they are calling ashmem API on a valid fd by
calling ashmem_valid first. Lets make the fstat syscall only if the
ioctl returns -ENOTTY. This means in the regular case, only 1 syscall is
needed (ioctl) vs the current 2 (fstat+ioctl).
Some data to show improvements in reduction of vfs_getattr calls in the
kernel by 10x when doing a camera.

Fastboot protocol doesn't include zero packets,
so make it possible to configure that.
Allow fastbootd to see how many bytes the handle
can read/write at once.

Previously, read and write would return 0
on success. Now it will return the number
of bytes read/write. This is more consistent
with other usb handles and is needed in order
to handle partial packets (for fastbootd).
Update usb_write in other usb handles
to return amount written.
Change transport_usb accordingly.

Fastbootd will reuses adb's functionfs transport
implementation.
Move it to daemon/include as well so it can be accessed
with "adbd/usb.h". Otherwise usb.h will conflict with
other imports.

This change enables flashing of the super partition without using
lpflash or adding explicit fastboot support for the liblp image format.

This is in preparation for adding sparse image support, to avoid
cluttering the more critical reading and writing logic.

Since some vendors will have firmware in mount points in
/mnt/vendor/..., we extend the ueventd script language to allow
specifying the firmware directories.
Also, move the existing 4 directories to ueventd.rc as a primary user
of this mechanism.
