[libvirt] [PATCH 08/10] vl.c: Support multiple CPU ranges on -numa option

This allows "," or ";" to be used a separator between each CPU range. Note that commas inside key=value command-line options have to be escaped using ",,", so the command-line will look like: -numa node,cpus=A,,B,,C,,D or: -numa node,cpus=A;B;C;D Note that the following format, currently used by libvirt: -numa nodes,cpus=A,B,C,D will _not_ work yet, as "," is the option separator for the command-line option parser, and it will require changing the -numa option parsing code to handle "cpus" as a special case.
