25fb2e9c39 iotests/common.pattern: Quote echos
From time to time, my shell decides to repace the bracketed numbers here
by the numbers inside (i.e., "=== Clusters to be compressed [1]" is
printed as "=== Clusters to be compressed 1").  That makes tests that
use common.pattern fail.  Prevent that from happening by quoting the
arguments to all echos in common.pattern.

30edd9fa50 tests/qemu-iotests: Don't use 'seq' in the iotests
The 'seq' command is not available by default on OpenBSD, so these
iotests are currently failing there. It could be installed as 'gseq'
from the coreutils package - but since it is using a different name
there and we are running the iotests with the "bash" shell anyway,
let's simply use the built-in double parentheses for the for-loops
instead.

11a82d1429 qemu-iotests: Improve portability by searching bash in the $PATH
Bash is not always installed as /bin/bash. In particular on OpenBSD,
the package installs it in /usr/local/bin.
Use the 'env' shebang to search bash in the $PATH.

Patch created mechanically by running:

  $ git grep -lE '#! ?/bin/bash' -- tests/qemu-iotests \
    | while read f; do \
      sed -i 's|^#!.\?/bin/bash$|#!/usr/bin/env bash|' $f; \
    done

8cedcffdc1 iotests: Drop use of bash keyword 'function'
Bash allows functions to be declared with or without the leading
keyword 'function'; but including the keyword does not comply with
POSIX syntax, and is confusing to ksh users where the use of the
keyword changes the scoping rules for functions.  Stick to the
POSIX form through iotests.

Done mechanically with:
  sed -i 's/^function //' $(git ls-files tests/qemu-iotests)

4401fdc77c qemu-io: Switch 'alloc' command to byte-based length
For the 'alloc' command, accepting an offset in bytes but a length
in sectors, and reporting output in sectors, is confusing.  Do
everything in bytes, and adjust the expected output accordingly.

dd0c35d69b qemu-iotests: Use zero-based offsets for IO patterns
The io_pattern style functions have the following loop:

  for i in `seq 1 $count`; do
      echo ... $(( start + i * step )) ...
  done

Offsets are 1-based so start=1024, step=512, count=4 yields:
1536, 2048, 2560, 3072

Normally we expect:
1024, 1536, 2048, 2560

Most tests ignore this detail, which means that they perform I/O to a
slightly different range than expected by the test author.

Later on things got less innocent and tests started trying to compensate
for the 1-based indexing.  This included negative start values in test
024 and my own attempt with count-1 in test 028!

The end result is that tests that use io_pattern are hard to reason
about and don't work the way you'd expect.  It's time to clean this mess
up.

This patch switches io_pattern to 0-based offsets.  This requires
adjusting the golden outputs since I/O ranges are now shifted and output
differs.

Verifying these output diffs is easy, however.  Each diff hunk moves one
I/O from beyond the end of the pattern range to the beginning.

ac5e2b201b qemu-iotests: test larger clusters sizes on qcow2
This patch adds test case 023 which tests some more cluster sizes. For
anythinger larger than 4k clusters we can't use requests that are l2_size or
more (128k for 1k clusters, 2 MB for 4k clusters, 512 MB for 64k clusters).
Therefore one of the common.pattern cases is changed and needs new expected
results for some old test cases.

8fc1024cee qemu-iotests: align test requests according to cluster size
Change the io_test and io_test2 functions to take the cluster size of the image
and the number of test requests to issue. Tests are changed to specify a
cluster size (usually 4k), but expected test results stay the same for now
(apart from qemu-img printing the cluster size now).

Based on a patch written by Christoph Hellwig.
