[PATCH] Perl Bindings trunk backport to 1.0.x

Hi,

It appears that there would unlikely be an 1.0.x update unless there
are security vulnerability discovered. So here is the patch back
porting all the memory leak fixes in perl bindings from trunk, for
people interested at the pre-1.1 period. This is also a side effect
of rename-tracking merge support in svk, to allow doing the merge
easily.

Also there is another patch for linking the swig runtime and
supporting library into SVN::Core, which is not in the trunk. This
allows multiple versions of perl to use correct bindings compiled with
respective version.

Cheers,
