This change removes the void* argument passing and instead uses C++11
features to avoid having to handle memory manually.

This change preserves any additional flags mount flags (e.g. MS_NODEV)
that any of the mounts would have. This avoids unnecessarily opening up
permissions, and also allows kernels that have additional restrictions
about what mount flags can be used to be happy with the remounts.

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.

In the RemoveFileIfExists it always return true even if error appeared
when using stat function.
It should distinguish different error. Such as ENOENT and ENOTDIR
we exactly know the file does not exist. But EACCES(current user has not
all search permission in the file path) and other errors appeared
we can't know whether file exits. So we should return false indicate
there are some error appeared.
Test: ran unit tests
