ioengine: Add fallocate ioengine

IO engine that does regular fallocate to simulate data transfer
as fio ioengine.
 DDIR_READ  does fallocate(,mode=FALLOC_FL_KEEP_SIZE,)
 DDIR_WRITE does fallocate(,mode=0) : fallocate with file extention
 DDIR_TRIM  does fallocate(FALLOC_FL_KEEP_SIZE | FALLOC_FL_PUNCH_HOLE)

This engine may be useful to perform various tests:
1) Generation highly fragmentated files
2) Various fs stress testing in parallel with others io activity
