gitweb: Refactor syntax highlighting support
This refactoring (adding guess_file_syntax and run_highlighter subroutines) is meant to make it easier in the future to add support for other syntax highlighing solutions, or make it smarter by not re-running `git cat-file` second time. Instead of looping over list of regexps (keys of %highlight_type hash), make use of the fact that choosing syntax is based either on full basename (%highlight_basename), or on file extension (%highlight_ext). Add some basic test of syntax highlighting (with 'highlight' as prerequisite) to t/t9500-gitweb-standalone-no-errors.sh test. While at it make git_blob Perl style prettier.
