MMD 25 - multiply

[Leopold Toetsch]

One more, and my fingers & brain are getting tired of these changes.

If someone wants to continue (and complete it during night here ;-),
it's a simple job:

1) vtable.tbl
- change existing signature of next infix operation
- add inplace variant directly below it

2) imcc/parser_util.c:is_infix()
- add the compare case for the MMD

3) make realclean; perl Configure.pl ... && make -s

4) fix all compiler errors in classes and dynclasses by looking at
already converted functions and adding the inplace variants

4a) remove code from dynclasses/py*.pmc, if it's the same as the Parrot
core base class, or adapt code

5) make test &&

6) svn ci
