Q does not recognize every single-token parameter

[cordney]

Follow-up from #13 (andreasf):

But additionally, Q does not recognize every single-token parameter and tracking those is a tedious task. Instead, once initial fixes are in place, the argument parsing should be revisited to no longer rely on this string-explosion based on whitespace character, i.e. tokenizing quoted and unquoted strings, ignoring any combination of whitespace characters in between.

We will add a standard parser for arguments, which respects specific Q Arguments, instead of a closed number of valid arguments.

This implicits a good error reporting, if arguments are not recognised by QEMU.
