Add ui.progress API

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())

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()

localrepo: add destroyed() method for strip/rollback to use (issue548).

Factor tags module out of localrepo (issue548). Currently only handles reading tags, and will soon grow support for tag caching. Could eventually deal with updating tags too.

localrepo: factor updatetags() out of readtags() (issue548).

localrepo: improve readability of _findtags(), readtags() (issue548). - rename many local variables - add some comments - refactor call to line.split() (catch ValueError rather than checking length of return value: one less local variable)

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.
