This patch adds a new test 255 that tests that a hole can be punched even when 
the
disk is full.  Reserved blocks should be used to allow a punch hole to proceed 
even
when there is not enough blocks to further fragment the file. To test this, the
file system is fragmented by punching holes in regular intervals and filling
the file system between punches. This will eventually force the file system to 
use
reserved blocks to proceed with the punch hole operation.

The work in this patch is a continuation from a previous patch set that has been
partially accepted.

v5->v6

Test moved out of 252 and put in its own test 255

_fill_fs and _test_full_fs_punch have been moved from common.punch
to test 255 and modified to use the _user_do routines in common.rc

_fill_fs has been optimized to stop once files smaller than a block
cannot be created.

Ah, sorry I obviously messed up the file add here. My apologies for the confusion! Will resend this one.
