tags: support 'instant' tag retrieval (issue548)

- modify _readtagcache() and _writetagcache() to read/write tag->node
  mapping for global tags
- if (and only if) tip unchanged, use that cached mapping to avoid
  reading any revisions of .hgtags
- change so tag names are UTF-8 in memory in tags.py, and converted to
  local encoding as late as possible (in localrepository._findtags())
