    webrick: compile RE correctly for beginning and end match
    
    Using ^ and $ in regexps means we can accidentally get fooled
    by "%0a" in HTTP request paths being decoded to newline
    characters.  Use \A and \z to match beginning and end-of-string
    respectively, instead.
    
    Thanks to mame and hsbt for reporting.
    
    * lib/webrick/httpserver.rb (MountTable#compile):
      use \A and \z instead of ^ and $
    * lib/webrick/httpserver.rb (MountTable#normalize): use \z instead of $
    * test/webrick/test_httpserver.rb (test_cntrl_in_path): new test
