[PATCH v2] xfstests: btrfs/311: sparse copy between different filesystems/mountpoints

Thanks Eric for reviewing and improving testcases btrfs/306, 309, 310 
and 311 !

I had just one comment: on line 70 the output was redirected to 
$seqres.fll instead of $seqres.full. Corrected patch below.

# Check if creating a sparse copy ("reflink") of a file on btrfs
# expectedly fails when it''s done between different filesystems or
# different mount points of the same filesystem.
#
# For both situations, these actions are executed:
#    - Copy a file with the reflink=auto option.
#      A normal copy should be created.
#    - Copy a file with the reflink=always option. Should result in error,
#      no file should be created.

[sandeen: mostly cosmetic changes]
