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.

as well.

This encourages device manufacturers to use
service.override over service and to remove healthd
on device, because it is one less step to do.

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.
Test: adb works

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.
Test: adb works

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.
Bug: 79173901
Test: image can be flashed to device and read by liblp
