Create a couple of XFS-specific tests -- one to check that growing
and shrinking the refcount btree works and a second one to check
what happens when we hit maximum refcount.

I suspect we need a _require rule for checking that something in
the test src directory has been built.

This is what _require_scratch_nocheck avoids.

i.e. do this instead:

_require_scratch_nocheck
.....

"$XFS_REPAIR_PROG" -o force_geometry -n "$SCRATCH_DEV" >> "$seqres.full" 2>&1 
status=$?
exit

Also, we really don't need the quotes around these global
variables.  They are just noise and lots of stuff will break if
those variables are set to something that requires them to be
quoted.

Cheers,

Dave.

Crapola, we also need punch-alternating, which doesn't appear until the next
patch.  Guess I'll go move it out of the next patch (or swap the order of
these two I guess.)

I added _require_test_program() which complains if src/$1 isn't built.

Ok.
