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())

#!/bin/sh
hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "1000000 0"
ls
echo This is file b1 > b
hg add b
hg commit -m "commit #1" -d "1000000 0"
hg co 0
# B should disappear
ls
