This is v2 of a concept that was first posted last September.  In the
meanwhile more options have been added to Meson, so the effect of the
change can hopefully be evaluated more accurately.  At least, the amount
of lines removed in the configure script is larger than the size of
the script itself!

Regarding the code itself, the main change is that the script has been
rewritten from Python to Perl.  The reasons for this are detailed in
the commit message.

For the parsing of an option to be completely automatic, there must be
no mentions of the corresponding variable in configure.  Patches 1 to
6 clean up some of the stragglers to enable more automatic conversions.
The only remaining options to be split between configure and Meson are
capstone, git, slirp, default_devices, cfi and xen.
