In preparation to possible automatic regression and performance
testing for the block layer I found that the iotests don't work
for all protocols anymore.

In commit 1f7bf7d0 I started to change supported protocols from
generic to file for various tests. Unfortunately, some tests
added in the meantime again carry generic protocol altough they
can only work with file because they require local file access.

The other way around for some tests that only support file I added
NFS protocol after confirming they work.

Add a test which discards a compressed cluster on qcow2. This should
work without any problems.

all these tests do anything of the following and thus fail with any
protocol other than file:
 - the tests use rm, cp or mv shell commands which only work on file
 - the tests use qcow2.py
 - the images construct new filenames (e.g. backing file names) and
   the logic is broken for anything else than file

A lot of image filename and paths are used unquoted.  Quote these to
make sure that directories / filenames with spaces are not problematic.

It's supposed to fail gracefully instead of segfaulting.

This patch introduces tests for protocols other than file, and
initially supports rbd and sheepdog.

The tests use bash language features like 'let', which aren't supported
by /bin/sh on systems that use a conservative shell like dash.  This
patch changes the interpreter to /bin/bash.

Blue Swirl notices that we were using the old FSF post address in the

to the gnu.org licenses homepage as suggested by Ben Pfaff.
