tags: implement persistent tag caching (issue548).

- rename findglobaltags() to findglobaltags1() (so the "no cache"
  implementation is still there if we need it)
- add findglobaltags2() and make findglobaltags() an alias for it
  (disabling tag caching is a one-line patch)
- factor out tagcache class with methods readcache() and writecache();
  the expensive part of tag finding (iterate over heads and find
  .hgtags filenode) is now in tagcache.readcache()
