Drop ext/mhash and add an emulation layer in ext/hash (5.3+), call for help

Hi, While working on the windows ports, I asked Sara about the mhash status in regard of the new shiny ext/hash. The plan is to remove ext/hash completely and emulate it in ext/hash to keep the BC. It could even a configuration flag if one likes to be sure to clean his code to use only the hash APIs. As I would love to do it myself, I sadly don't have the time to do any time soon. It would rock if someone could take the hand on it and send a patch to us. I can help for any windows issue if any (that's what I focus on these days).
