ext4: add EXT4_IOC_ALLOC_DA_BLKS ioctl

(cherry picked from commit ccd2506bd43113659aa904d5bea5d1300605e2a6)

Add an ioctl which forces all of the delay allocated blocks to be
allocated.  This also provides a function ext4_alloc_da_blocks() which
will be used by the following commits to force files to be fully
allocated to preserve application-expected ext3 behaviour.
