When a large IO is done as a single buffer, there is no guarantee
that it will partially succeed when close to ENOSPC. The test
assumes that the kernel is going to break the write down into
smaller chunks (i.e. buffered IO breaking it down into PAGE_SIZE
allocations), but certain configurations will not do this. e.g.
extent size hints are set or DAX is being used) and hence the large
write fails completely as there is not space for the entire
allocation to be made.
Hence break the final write in the test up into multiple small
writes, thereby acheiving the same effect - ensuring that we can
write more data after removing some space....

Added -P option to $DF_PROG and changed the invocation of
'df' command in generic/{251,260,273,275} testcases
with $DF_PROG.
Otherwise the testcases will fail if the scratch
device has a long name (for example, if it's an LVM volume).
Because df outputs its usage stats with two lines:
/dev/mapper/xfstests-disk1
3030800 4608 2868908 1% /tmp/mnt/disk1

Introduce a top level common directory and move all the common.*
files into it. Because there is now a directory named common, the
prefix can be dropped from all the files. Convert all the tests to
use this new directory for including common files.
for f in common.*; do \
git mv `echo -n "$f " ; echo $f | sed -e 's;n\.;n/;'` \
done

Essentially the change is simply this. Converting:
... >> $seq.????
to:
.... >> $RESULT_DIR/$seq.????
so that output files are directed to the defined output directory.
sed to the rescue:
$ sed -i -e '/^seq=.*$/a seqres=$RESULT_DIR/$seq' -e 's/seq.full/seqres.full/' tests/*/*
will do most of the work automatically.
