[PATCH] xfstests: enable many tests to run on ext2/3/4

[Eric Sandeen <sandeen@redhat.com>]

This gets many of the tests running on ext4 (and should on ext2/ext3
as well).

A few things could still be cleaned up; rather than -xfs, -ext3, -ext4
etc it'd be better to do --fstype xfs or whatnot, and lose as much of
the special-casing as possible.  But this gets it going, so maybe
worth merging now as a first step.

This creates a new supported_fs "generic" type which should run on
any generic filesystem (well, assuming it supports acls & xattrs, along
with general posix-ness).

It also adds a "generic" group, so you can do:

./check -ext4 -g generic

and that way it'll avoid any fs-specific tests.  They wouldn't
fail anyway, but it gets noisy to see all the "notrun" tests.

Long term there's probably a better way to do this; maybe just
skip all output when there's a fs type mismatch, not sure.
Right now fs compat info is in the test itself, so putting "generic"
into the group file might kind of be a sort of layering violation,
whaddya think?  (OTOH "udf" was there already; maybe non-generic
tests -should- have fs types in the group file and then you could do:

./check -ext4 -g generic -g ext4

or that last part could be automatic...)

There are a few more tests which could almost work for ext4
with a bit more work:

020 runs into different attribute limits I think
051 ditto but for acls
075 uses the -x preallocation call for xfs
062 gets a different recursive walk of files
164 uses xfs_io to do file mapping
192 is doing something odd I haven't sorted out yet
