plperl intial pass

on the patches list, I posted the first files
for suuport for using perl as the procedural
language.

The makefile uses libtool (probably incorrectly).

It is not 'safe'.

Perl XS modules cannot be used.

Using Perl in rules hasn't even been thought about.

IF the code looks suspiciously like Jan's code
for pltcl - well, it _is_ Jan's code for pltcl
horribly mangled.

It compiles and runs for me. YMMV.

more code and docs to follow.
