Prepare for ICU update

- libicule and libiculx do not exist anymore in newer ICU versions
(harfbuzz replaces them), but we didn't actually use them, so remove
them from the build feature and from the package dependencies
- Add namespace usage marcos since the newer ICU packages put ICU things
in a namespace, making it easier to have multiple versions of ICU used
side by side.

No functional change intended, but this makes it possible to build the
code with either ICU 57 (for gcc2) or 66 (for other architectures).

Actual build fix.

Build fix.

BLanguage: check locale validity in SetTo.

Fixes #15514

Update icu x86_64 package with namespace renaming enabled.

"Renaming" means the icu namespace is suffixed with the version number,
atm icu_55. Using "renaming" allows to use two different versions of ICU,
thus easing upgrades. For instance haikuwebkit uses a current version of ICU,
while the system uses a newer one after an upgrade.

* Replace all uses of the icu namespace in our public headers, with a macro
defaulting to icu. As the namespace is only used for private fields pointers,
there should be no impact.
* Locale kit *.cpp have to import the macro from <unicode/uversion.h> *before*
including any locale headers. Ditto for a Time preferences cpp file. This way,
the correct current icu namespace is referenced.
* Fixes bug #12057.

* update (not-so-)optional package ICU to 4.8.1, which contains interesting stuff
for message formatting
* adjust LocaleKit to use namespace 'icu', as ICU has been configured to no longer
use a version specific namespace
* adjust LocaleKit to general API changes in ICU 4.8
Note: all software using ICU (like WebPositive) needs to be rebuilt!
Note: the ICU package for PPC needs to be updated before it can be used!

* Added BLanguage::GetIcon(), and BLocaleRoster::GetFlagIconForLanguage(). The
former just calls the latter. Getting the flag for a language is pretty
simplistic for now, but it won't return the wrong flag, just only a few known
ones (should be enough for ReadOnlyBootPrompt, at least).
* Ordered methods in declaration order.

* Fixed trivial merge conflict in src/system/libroot/posix/locale/nl_langinfo.cpp

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

Largish cleanup sweep concerning the Locale Kit (sorry it got so big):
* refactored private/mutable stuff out of LocaleRoster into MutableLocaleRoster
* moved management of Locale/Time settings file and broadcasting of any changes
out of preflets and into MutableLocaleRoster
* added proper sorting to the listviews of the Locale preflet
* the Time preflet no longer overlaps long timezone names into the actual time
* several fixes with respect to leaking ICU objects, esp. in BCountry
* the locale roster no longer passes out references to its own BCountry object,
but uses copies, instead - this makes locking superfluous, as the clients'
BCountry objects can no longer be changed by the setting a new default
country in the locale roster
* removed pretty useless POSIX-style symbol fetching from BCountry - if we
need that at all, it should live in the dedicated formatter classes
* adjusted readonlybootprompt, dstcheck and Deskbar to the changed Locale API
* refactored existing Time-formatter into TimeUnitFormat and DurationFormat
(the latter of which is now used by AboutSystem)
* added stubs for Date, DateTime and Time formatters
* lots of coding style fixes throughout the Locale Kit and the Locale and Time
preflets
This will probably break most external apps making use of the Locale Kit - it
does break WebPositive.

Update ICU to 4.4
* Remove 4.2 sourcecode
* ICU is now an optional package (mandatory)
* Adjust the namespaces and libraries names where needed


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37498 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed BLocaleRoster::GetLanguage() to a signature that makes more sense,
and looks more like the rest of the API.
* Also, it will now return an appropriate error code if the language couldn't
be allocated (anything else than B_OK is an improvement :-)).
* Several changes in BLanguage:
- GetName() now gets a BString reference, also
- it now returns the name in its own language, ie. for German this would
always be "deutsch", no matter the current language settings, and finally,
- it now empties the string it gets before adding the name.
- added GetTranslatedName() that behaves like the previous version.
- added const where it made sense (ie. almost everywhere).
- Code() now returns the code of the language only.
- ID() now returns the full ID of this language, ie. including country,
variant, and keywords if any.
- added Country(), and Variant().
- renamed IsCountry() to IsCountrySpecific().
- added IsVariant().
* Cleaned up Language.h, minor cleanup in LocaleRoster.cpp.
* Removed the whole move item logic from LanguageListView; while this was not
only spaghetti code, it doesn't make much sense in the first place.
* Instead of removing stuff from the left, and even worse, moving all countries
for a language even if only one had been dragged, we now only mark the items
that are already in the preferred list, and only those.
* Fixed various mixups of FullList*() vs. *() methods that could lead to things
like bug #5896.
* Pressing the delete key in the preferred list view will now remove the
language.
* Moved LocaleWindow specific message constants to LocaleWindow.cpp; Locale.h
is supposed to contain application wide constants.
* The drop logic is now in LocaleWindow.
* We now make sure that each base language can only be in the list once.
* Lots of cleanup, even though I mostly replaced spaghettie code with different
looking spaghettie code - still, I think things have slightly improved.

This should have been part of previous commit :
Add Language->IsCountry to tell if a language holds a country specifier (like fr_FR) or not (fr alone). This allows separating them in the preflet.

Stumbled across some problems while using the Locale Kit and added TODOs
accordingly.

- Locale kit : made the language class live. It now uses ICU as a backend as expected
- Some changes in the locale roster to allow instanciating a language
- Locale preflet : use this new API instead of directly calling ICU
Side effect : all languages in Locale window are now displayed in the current locale. It makes more sense as otherwise the list would be unsortable. However it can get annoying if you mistakenly set a strange language as default.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35210 a95241bf-73f2-0310-859d-f6bbb57e9c96
