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.
