Reimplement search in terms of owl_regex. The current implementation of stristr has problems and there isn’t a good replacement available. This was its only caller, so we can get rid of it now. Also, this will make it possible to search with arbitrary regexes if someone feels like coming up with a syntax. Signed-off-by: Anders Kaseorg <andersk@mit.edu>
