Combine code that finds mentions into one place and add hook points 

Combined the code that finds mentions of other profiles into one place.

common_find_mentions() finds mentions and calls hooks to allow
supplemental syntax for mentions (like OStatus).

common_linkify_mentions() links mentions.

common_linkify_mention() links a mention.

Notice::saveReplies() now uses common_find_mentions() instead of
trying to parse everything again.
