localrepo: rename in-memory tag cache instance attributes (issue548). - self.tagscache to self._tags - self._tagstypecache to self._tagtypes - this is for consistency, readability, privacy, and to subtly hint that "caching" is something else

localrepo: factor _findtags() out of tags() (issue548). This makes in-memory caching the sole responsibility of localrepo, eliminating some localrepo code that was duplicated in mq and bookmarks.

test-tags: enhance the test to probe tag caching better (issue548). - give detailed dumps of .hgtags and localtags content - repeat some query operations to expose cache bugs - ensure that rollback/strip undo tagging operations

test-tags: clarify test output; simplify test script a bit (issue548). - use simpler way ('hg id') to get current changeset id - add 'echo' statements to guide the eye when reading output - add some more output to clarify the state of .hgtags - drop '-d' option from every commit/tag, since run-tests.py does this (although with a different timestamp, so changeset ids differ)

for calls expecting bool args, pass bool instead of int str.splitlines and email.message.as_string both expect a bool argument defaulting at False: replace f(1) by f(True) and f(0) by f()

store: eliminate reference cycle in fncachestore no reference to self in fncacheopener Inspired by Adrian Buehlmann

win32mbcs: add special wrapper for osutil.listdir(). osutil.listdir() may misinterpret 0x5c of MBCS 2nd. byte as path separator. New wrapper prevents this by adding it beforehand.

win32mbcs: wrapper supports keyword arguments and dict result. The keyword arguments are also decoded before calling original. And dict of return value is also encoded back.

gendoc: fall back to pure modules if C extensions are not available (issue1711)

Don't copy hidden files/directories during `setup.py install` This is useful if a copy of Mercurial is stored in a Subversion repository so that the .svn directories don't get copied.

commands: hide deprecated commands. A command is considered deprecated if the word "DEPRECATED" is found in the doc string. Such commands are hidden from non-verbose help.

hgignore.5.txt: improved description of matching Improved the description of the matching behavior used with .hgignore. Made some minor language improvements.

Fix issue1738 for strip too. I see no reason to open every touched file at once.

setup.py: don't pollute the current directory with temporary files

Make patch.diff filelog cache LRU of 20 files. Fixes issue1738. 20 files is as fast as 200 for hg diff -r 28015:30103 of mozilla-central. Ideally we'd use util.lrucachefunc, but the interface doesn't quite work.
