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:

iotests: 077: Filter out 'resume' lines

In the "Overlapping multiple requests" cases, the 3rd reqs (the break
point B) doesn't wait for the 2nd, and once resumed the I/O will just
continue. This is because the 2nd is already waiting for the 1st, and
in wait_serialising_requests() there is:

/* If the request is already (indirectly) waiting for us, or
* will wait for us as soon as it wakes up, then just go on
* (instead of producing a deadlock in the former case). */

Consequently, the following "sleep 100; resume A" command races with the
completion of that request, and sometimes results in an unexpected
order of output:

> @@ -56,9 +56,9 @@
> wrote XXX/XXX bytes at offset XXX
> XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
> blkdebug: Resuming request 'B'
> +blkdebug: Resuming request 'A'
> wrote XXX/XXX bytes at offset XXX
> XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
> -blkdebug: Resuming request 'A'
> wrote XXX/XXX bytes at offset XXX
> XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
> wrote XXX/XXX bytes at offset XXX

Filter out the "Resuming request" lines to make the output
deterministic.

block/io: optimize bdrv_co_pwritev for small requests

QEMU reads the same block twice in this case which is
