[modperl-embperl] Patch to 2.2.0 Embperl.pm to fix cookie header handling under mod_perl 2

Hi all,

I'm surprised this hasn't come up for anyone else but there is a problem
with line 355 of Embperl.pm when it attempts to get the request cookie
headers using $req_rec->header_in(), namely header_in() doesn't exist in
mod_perl 2 :) (See:
http://perl.apache.org/docs/2.0/user/porting/compat.html#C__r_E_gt_heade
r_in_)

Simple patch below. The APR::Table is an extra "require" call as
headers_in() returns an APR::Table object and the hash isn't accessible
in a tied manner unless that module is loaded.

I haven't tested this under earlier mod_perl versions - you may need a
similar "require Apache::Table ;" in the appropriate stanza for those.
