[PATCH 0/4] yacc.c: provide the Bison version as an integral macro

Balazs Scheidler asked for the Bison version as a numeric macro in
https://github.com/akimd/bison/issues/55.  The series of patches
recycles the existing YYBISON from simply being `1`, to being the
current version, e.g. `30704`.

I used a scale of 100, which should not be a problem.  We could use a
scale of 1000, or even something not regular as Boost does (107400 is
1.74).

Paul, I'd appreciate your opinion on this scale, and time permitting,
a quick check on the way I used intprops to compute that version
integer.

Cheers!
