qemu-block xlator is not used by anyone, or so I'm told.
It's also substantially out of date. There's little reason to keep
it in our sources. (And FedoraProject doesn't like bundled software
either.)

1) Avoid hangs on unmounting NFS on NetBSD
NetBSD umount(8) on a NFS mount whose server is gone will wait forever
because umount(8) calls realpath(3) and tries to access the mount before
it calls unmount(2). The non-portable, NetBSD-specific umount -R flag
prevent that behavior.
We therefore introduce UMOUNT_F, defined as "umount -f" on Linux and
"umount -f -R" on NetBSD to take care of forced unmounts, especially
in the NFS case.
2) Enforce usage of force_umount wrapper with timeout
Whenever umount is used it should be wrapped in force_umount with
tiemout handling. That saves us timing issues, and it handles the
NetBSD NFS case.
3) Cleanup kernel cache flush.
We used (cd $M0 && umount $M0 ) as a portable kernel cache flush
trick, but it does not flush everything we need on Linux. Introduce
a drop_cache() shell function that reverts to previously used
echo 3 > /proc/sys/vm/drop_caches on Linux, and keeps
(cd $M0 && umount $M0 ) on other systems.

- For some odd reason, setfattr(1) could fail on big-file just after
it was created by touch(1). Add a test in between to wait for the
file to be visible by ls(1).
- After switching to a snapshot, the file content is still in kernel
cache, and the old content may be readen for a few seconds after
the snapshot switch. Use ( cd $M0 && umount $M0 ) to flush vnodes
and therefore invalidate the cache.
- Unmount the mount point at the end of the test for the cleanliness
sake.

- `wc -l` on OSX/FreeBSD adds spurious spaces, this clobbers
up TAP output parsers - fix it.
- `umount -l` doesn't exist on OSX/FreeBSD use 'umount -f' if
available.
- Add check for 'file' version, to handle mime type variations
across versions
- Converge 'glusterfs --attribute-timeout=0 --entry-timeout=0'
into '$GFS'
- Modify remaining 'mount -t nfs' to use 'mount_nfs'
- Update sha1sum for OSX to use 'openssl sha1'.

Support the readdirp fop in qemu-block to ensure that image files
are handled correctly when readdirp is enabled. E.g., without
readdirp support, incorrect stat data for formatted files can be
reported back (and cached) via the client.

This patch adds support for internals snapshots using QCOW2 and
general framework for external snapshots (next patch) with
QCOW2 and QED.
For internal snapshots, the file must be "initialized" or
"formatted" into QCOW2 format, and specify a file size.
Snapshots can be created, deleted, and applied ("goto").
e.g:
// Format and Initialize
sh# setfattr -n trusted.glusterfs.block-format -v qcow2:10GB /mnt/imgfile
sh# ls -l /mnt/imgfile
-rw-r--r-- 1 root root 10G Jul 18 21:20 imgfile
// Create a snapshot
sh# setfattr -n trusted.glusterfs.block-snapshot-create -v name1 imgfile
// Apply a snapshot
sh# setfattr -n trusted.gluterfs.block-snapshot-goto -v name1 imgfile
