Connor Kuehl 2b99cfce08 block/rbd: Add an escape-aware strchr helper
Sometimes the parser needs to further split a token it has collected
from the token input stream. Right now, it does a cursory check to see
if the relevant characters appear in the token to determine if it should
break it down further.

However, qemu_rbd_next_tok() will escape characters as it removes tokens
from the token stream and plain strchr() won't. This can make the
initial strchr() check slightly misleading since it implies
qemu_rbd_next_tok() will find the token and split on it, except the
reality is that qemu_rbd_next_tok() will pass over it if it is escaped.

Use a custom strchr to avoid mixing escaped and unescaped string
operations. Furthermore, this code is identical to how
qemu_rbd_next_tok() seeks its next token, so incorporate this custom
strchr into the body of that function to reduce duplication.

Connor Kuehl f7afa7daa0 iotests/231: Update expected deprecation message
The deprecation message in the expected output has technically been
wrong since the wrong version of a patch was applied to it. Because of
this, the test fails. Correct the expected output so that it passes.

Jeff Cody 66e6a735e9 block/rbd: add iotest for rbd legacy keyvalue filename parsing
This is a small test that will check for the ability to parse
both legacy and modern options for rbd.

The way the test is set up is for failure to occur, but without
having to wait to timeout on a non-existent rbd server.  The error
messages in the success path show that the arguments were parsed.

The failure behavior prior to the patch series that has this test, is
qemu-img complaining about mandatory options (e.g. 'pool') not being
provided.
