Allow switching of timezone string to messages locale, too.

* adjust POSIX locale backend to redirect the timezone string
through the messages/time-locale indirection

Add our implementation for wcscoll() and wcsxfrm().

* add Wcscoll() and Wcsxfrm() ICU locale backend
* provide implementations of wcscoll() and wcsxfrm() that are using
the respective methods of the locale backend

Improve timezone names returned by POSIX functions.

* Use TimeZone::SHORT specifier instead of SHORT_COMMONLY_USED, since
the former yields more appropriate (textual) values. Strangely enough,
it used to be the other way around, which is why we didn't used SHORT
in the past.

Bring rewritten multibyte-support into repository.

* update copyrights of locale backend files

Multibyte-support has been rewritten to use ICU as backend.
While this does not necessarily work properly in every aspect
(e.g. the shell still has [different] problems with multibyte-
characters now), it does fix #6263 and #7700.

* fix support for influencing tzset() via TZ environment variable
(now at least <std> and <offset> are supported properly)
* instead of creating a TimeZone object whenever needed, we now
create it in tzset() and keep it around
* add tests for TZ to locale_test

* Merged weak-symbols branch.
* Fixed trivial merge conflict in src/system/libroot/posix/locale/nl_langinfo.cpp
* Fixed gcc 2 compilation of src/system/glue/init_term_dyn.c.

Adjust tzset() implementation to better follow the POSIX specs and
make some more perl tests happy.
* no longer expect a ICU timezone ID in the TZ environment variable,
but only expect this format if the TZ-value is starting with ':'
* accept "standard" TZ-values like "EST5" (of which only "EST" is
relevant to us) - if such a value is specified, we hardcode the
timezone name to the given value, no matter how ICU calls it
* adjust tests accordingly

* fix wrong signedness in values put into global 'timezone' variable,
the POSIX specs are a bit vague on this (to say the least)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38606 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implement tzset(), gmtime(), localtime() and mktime() on top of ICU
* no longer keep a separate time-backend, since the implementation needs to
access (data of) the locale backend anyway
* moved more stuff from localtime_fading_out.c to localtime.cpp
* added respective tests to locale_test
* added two more tests copied from glibc, test_time.c and tst-mktime.c
