Local version of fstrim was dropped so that we depend on upstream version which is now available via FSTRIM_PROG. _require_fstrim was added to check if fstrim is available in the system and _test_batched_discard to check if we can run fstrim on certain mountpoint. Also tests 251 and 260 were modified to reflect this change.

# FS QA Test No. 260
|
|
#
|
|
# Purpose of this test is to check FITRIM argument handling to make sure
|
|
# that the argument processing is right and that it does not overflow.
