Add $r variable which holds Apache2::RequestRec if script is run under
mod_perl (if $ENV{MOD_PERL} is defined). It is used as argument to
constructor of CGI object (needs CGI module version at least 2.93).
It is needed for further mod_perl support, for example adding
headers using Apache2::RequestRec methods instead of making Apache
to have to parse headers (to add it's own HTTP headers like Server:
header).
Following advice from CGI(3pm) man page, precompile all CGI routines
for mod_perl.
All this makes gitweb slightly faster under mod_perl (436 +/- 23.9 ms
for summary of git.git before, 429 +/- 12.0 ms after, according to
'ab -n 10 -k "http://localhost/perl/gitweb/gitweb.cgi?p=git.git";').

The idea is to have gitweb run under CGI and under mod_perl 1.0 and 2.0
without modifications, but making use of mod_perl features which make script
faster, like for example adding headers via mod_perl API and not via parsing
headers by Apache. In the future the plan is to be able to run gitweb under
not only current ModPerl::Registry (or Apache::Registry in mod_perl 1.0) but
also as a mod_perl handler, and as a FastCGI script using CGI::Fast.
Current portion of mod_perl cpecific additions is mod_perl version agnostic,
and avoids loading any mod_perl Perl modules.
I'd like to have it (and further mod_perl patches) reviewed by someone
better versed in mod_perl.
