[PATCH 0/2] gitweb: Add support for running gitweb as FastCGI script

This series requires the following patch:

  [PATCH 3/5] gitweb: Use nonlocal jump instead of 'exit' in die_error
  http://article.gmane.org/gmane.comp.version-control.git/145678

which is present as c42b00c commit in 'pu', as part of 'jn/gitweb-caching-prep' branch, which was merged into 'pu' at 97153ab7.

This patch adds support for FastCGI directly to gitweb.perl (so it would be present in gitweb.cgi); selecting between FastCGI and CGI is done via command-line switch (command-line option). It uses CGI::Fast, which is core Perl module.

It is port of old patch by Sam Vilain from 2006 to new gitweb announced in

  "Re: gitweb testing with non-apache web server"
  http://article.gmane.org/gmane.comp.version-control.git/24718

The preparatory patch is refactoring work, to not need to have request loop around large parts of code. I think the preparatory patch makes gitweb code more clean.

The alternate solution would be to add gitweb.fcgi wrapper, like e.g.: in the following patch by Eric Wong

  "[PATCH 1/2] gitweb: add a simple wrapper for FCGI support"
  http://thread.gmane.org/gmane.comp.version-control.git/35920/focus=35921

which was part of the "[0/2 PATCH] FastCGI and nginx support for gitweb" series. (Note that the patch does 'do $gitweb_cgi;' without checking for errors, see the bottom of `perldoc -f do` documentation on how it should be done).
