Add two scripts: "nextid" finds the next available test ID number in a
group, and "mvtest" relocates a test, fixes the golden output, and
moves the group entry for that test.
v2: sorting group files should preserve group order; nextid should use
the same algorithm as new; move both tools to tools/.

Don't leave cruft behind on the test device's filesystem, so as to
avoid filling it with debris.

Fix the error messages in the golden output for generic/15[78], which
examine the responses to invalid inputs as returned by the
clone/clone_range/extent_same ioctls. Also fix a filtering omission.

This use of TESTDIR is highly confusing. When I see TESTDIR I think
that it's the mount point of the test device, not potentially some
directory on the scratch device.
I see that this occurs through lots of tests, not just these new
ones. Can you do a pass across the tests with, say, sed and rename
all these to something less confusing? e.g. "testdir", in lower
case, makes it clear that it's a local variable, not the global test
device mount point.... (i.e. test local variables are lower case,
exported test harnes variables are upper case ;)
Separate patch/pull req is fine.
Cheers,
dave.

No problem. Will give it a spin on the test harness before sending.
(Yikes, it's a 272K patch...)

See what happens when we ENOSPC while growing a btree on behalf of
some reflink operation.
