Create a Gitweb::Request module in 'gitweb/lib/Gitweb/Request.pm'
to store and handle all the cgi params and related variables
regarding the gitweb.perl script.
This module is intended as standalone module, which does not require
(include) other gitweb' modules to avoid circular dependencies.
Subroutines moved:
evaluate_uri
evaluate_query_params
Update gitweb/Makefile to install Gitweb::Request module alongside gitweb
