Embedding block driver options in filenames is getting worse as time
goes on.  I recently tried to refactor and eliminate
QEMUOptionParameter so that we only use QemuOpts instead of two
different option APIs.  Part of that involves keeping separate
per-block driver (i.e. -blockdev) options lists, which would allow us
to pass proper options to block drivers instead of embedding them in
the filename.

I got stuck because today the protocol and format QEMUOptionParameters
get concatenated in some cases.  Concatenation is not really supported
by QemuOpts :).

Anyway, here's the current state if anyone is interested:
