QemuOpts: qemu_opts_parse: fix id= parsing

We can't use get_param_value(), it can't handle parameters without
'=' in there. Examples not working because of that:

-device foo,id=bar
  -device file=/path/image,format=qcow2,snapshot,id=disk0

qemu-option: fix parse_option_number().

It works much better when parse_option_number actually
returns the number parsed ...

Common breakage resulting from this bug is that
'qemu -hda foo.img -cdrom bar.iso' stops working
(cdrom isn't there).

QemuOpts: framework for storing and parsing options.

This stores device parameters in a better way than unparsed strings.

New types:
QemuOpt - one key-value pair.
QemuOpts - group of key-value pairs, belonging to one
device, i.e. one drive....

Create qemu-option.h

This patch creates a new header file and the corresponding implementation file
for parsing of parameter strings for options (like used in -drive). Part of
this is code moved from vl.c (so qemu-img can use it later).

The idea is to have a data structure describing all accepted parameters. When...
