[PATCH 0/5] gitweb: Miscellaneous improvements, in preparation for caching support

Those are miscellaneous improvements to gitweb, that were part of series that adds output caching support to gitweb. Nevertheless they make sense even outside gitweb caching.

would be useful to add FastCGI (CGI::Fast or FCGI) support to gitweb.

"gitweb: Move generating page title to separate subroutine" is pure refactoring currently, but it improves code quality by reducing indent level (nesting) in git_header_html.

The patches are independent, beside "gitweb: Add custom error handler using die_error" depending on changes introduced in "gitweb: Use nonlocal jump instead of 'exit' in die_error".
