color-words: make regex configurable via attributes
Make the --color-words splitting regular expression configurable via
the diff driver's 'wordregex' attribute. The user can then set the
driver on a file in .gitattributes. If a regex is given on the
command line, it overrides the driver's setting.
We also provide built-in regexes for the languages that already had
funcname patterns, and add an appropriate diff driver entry for C/++.
(The patterns are designed to run UTF-8 sequences into a single chunk
to make sure they remain readable.)
