Improve/fix tab view layout as discussed

See http://www.freelists.org/post/haiku-development/Unifying-visuals-of-BTabView-usage

Besides the tab bar going the full width of the window, also some
layouting tweaks to several apps and prefs.

Still missing: the first (and last) tabs in the tab bar should be inset by
B_USE_WINDOW_SPACING so the controls in the tab view line up nicely.
I think I remember stippi wanting to look into it... :)

Move DateTimeFormat and NumberFormat out of BLocale

* ... and adjust all callers
* Remove NumberFormatImpl: we rely on ICU to provide this and it can be
fully wrapped into the C++ file. The class was a stub anyway.
* "Monetary" format is included in NumberFormat for now. There may be a
more generic solution to handle monetary and BTimeUnitFormat (and other
arbitrary units)

Move time formatting to BTimeformat.

* Harmonize API for all B*Format to take an output BString by reference
as the first parameter,
* Move the FormatTime methods from BLocale to BTimeFormat
* Adjust all callers for BTimeFormat, BTimeUnitFormat and
BDurationFormat.

Adjust all BDateFormat callers again.

BDateFormat: improve API

* Use a reference rather than a pointer for the output string, removing
the need for NULL checks (which were missing, anyway)
* Adjust callers to that change
* Add new Format variant taking a BDate argument

Move date formatting from BLocale to BDateFormat

* There is a little code duplication. This will be moved to BFormat once
the time and datetime formatting is also moved out of BLocale
* The way to create a BDateFormat from a BLocale is still open for
discussion. I'm undecided between making BDateFormat a member of
BLocale, or adding a BDateFormat(const BLocale&) constructor.
* Adjust all users of the API.

Add Deskbar clock settings to Time Preferences

* Added a new Clock tab to the Time preflet. Added Clock related
controls there. They all function by communicating with Deskbar.
* Put controls in a BBox controlled by the Show clock checkbox.
This more clearly shows that all the clock settings are dependent
on the show clock setting since it doesn't matter what your clock
settings are if you don't show the clock.
* Make revert work.
* Split clock settings into it's own file and struct.
* Re-add the time zone setting.
* Remove the clock settings from the Deskbar preference window, they
are in Time now.
* Make Locale preferences accepts B_LOCALE_CHANGED message, although
not used.

More catalog-related cleanup.

* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h

The renamed macros require adjustments to all external applications
using catalogs.

* 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.

One more monster commit (sorry ...) concerning the Locale Kit:
* extracted new class BFormattingConventions from BCountry, which
manages the formatting conventions from a given locale and
allows to get/set the four different date/time formats supported
by ICU-locales as well as number and monetary formats
* overhauled the Locale preflet:
+ drop editing features for all formats, since I don't think
they do not make much sense to have in a prefs GUI - being
able to select from the existing locales should be good
enough. Please note that you can still change the formats
programmatically in an application.
+ renamed the 'Countries' tab to 'Formatting'
+ the locale formatting conventions list in the 'Formatting'
tab is now hierarchical for easier access (less scrolling)
+ fixed functionality of 'Revert' and 'Defaults' buttons
+ added support for using the month/day-names of your preferred
language during date formatting
* adjusted BLocale to ask BFormattingConventions for the current
formats when formatting dates and times and to offer 4
different format styles (full, long, medium and short).
* adjust all classes formatting dates/times to pick the
appropriate format style
* BLocaleRoster no longer directly archives/unarchives the
individual formatting conventions but delegates that to
BFormattingConventions

Next step of Locale Kit refactoring:
* BLocale now keeps language and country completely separate and
mixes the formatting conventions into the current language's locale
when formatting dates and times (needs to be done for number- and
currency-formatting, too, since the digits may not be in the
preferred language)
* optimized fetching of the flag icons such that they are all loaded
in one go (by the locale roster) - this alone speeds up the Locale
preflet considerably
* worked on fixing the language confusion in the Locale preflet
* fixed a couple of bugs in the Locale preflet that would lead to
illegal characters being displayed in the date-subpart menus


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39013 a95241bf-73f2-0310-859d-f6bbb57e9c96

* removed all BLocale-related getters from BLocaleRoster - they're available
in BLocale (which is accessible via be_locale)
* adjusted all users accordingly

Adjustments to Locale preflet
* renamed Locale.{h,cpp} to LocalePreflet.{h,cpp} as having two headers named
Locale.h confuses jam (as a result, the Locale preflet did not depend on
headers/os/locale/Locale.h)
* style adjustments (mostly order of headers)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38455 a95241bf-73f2-0310-859d-f6bbb57e9c96

Preliminary support for adjusting the money format in the locale preflet :
* API for formatting a number and recovering the field positions
* Some changes in the preflet to display the formatted number and start filling in the fields.

Update some apps/add-ons/preflets for impending changes to the layout API, specifically the layout builders. Also do a bit of style and layout cleanup in some places. This is part of #6407. Everything I've updated should look and function the same as it did before.
