libcutils: ashmem check fd validity
- collect st_rdev on open, or when required, for /dev/ashmem.
- check in all cases if fd is a character device and matches rdev.
- requires that we have open, read and write access to /dev/ashmem
to check, assumption being that if we can not, then we have no
right playing with the associated misdirected file descriptor.
NB: ashmem libcutil library entry points can no longer be called in
signal context.
