69caabb3af i18n: cache the result of every gettext call 
In looking at profiler output for 'hg log' on mozilla-central, I
noticed we spent a _huge_ amount of time in gettext relative to what
it's doing. Caching provides a roughly 15% performance improvement
even on repositories as small as hg.

e49fb83975 i18n: use datapath for i18n like for templates and help 
To avoid circular module dependencies we initialize i18n from util when
datapath is found.

cc6b6f4d1b i18n: detect UI language without POSIX-style locale variable on Windows (BC) 
On Windows, it isn't common to set LANG environment variable. This patch makes
gettext honor Windows-style UI language [1] if no locale variables are set.

Because of this change, LANG=C or HGPLAIN must be set in order to disable
translation on non-English Windows.

dependency for i18n.

5f24d65643 HGPLAIN: allow exceptions to plain mode, like i18n, via HGPLAINEXCEPT

while preserving different behaviors like internationalization.

3eefab1b9b i18n: translate each paragraph separately 
Makes translation work easier by reducing message sizes and avoiding
invalidating whole messages on small changes or additions to the
original text.

48b845981a ui: add HGPLAIN environment variable for easier scripting 
If HGPLAIN is set, the following settings are ignored when read from
hgrc files:

- ui.debug
- ui.fallbackencoding
- ui.quiet
- ui.traceback
- ui.verbose
- defaults.*

Localization is also disabled.

Equivalent options set via command line are honored.

7f3f8dbbe2 i18n: encode output in user's local encoding 
This makes the translated output obey the HGENCODING environment
variable or the preferred encoding as set by the LANG or LC_ALL
environment variables.

Python 2.4 has a lgettext method which is similar, except that it
doesn't know about HGENCODING or the settings in .hgrc.

b8064b97f3 i18n: lookup .mo files in private locale/ directory 
This default is to look for /usr/share/locale/xx/LC_MESSAGES/hg.mo for
language xx, but this code will instead do the lookup from locale/ or
mercurial/locale/ relative to the root of the Mercurial source tree.

d1c48b4dad Enable gettext translations 
The new demandimport eliminates most of the gettext performance hit of
importing gettext, which was doubling the run time for 'hg'.

Now, with 'hg tip':
