linkcatkeys: Avoid discarding potential error values.

Spotted by Clang and the [[nodiscard]] patch.

CID 603359: missing break in switch/case.

s/OpenBeOS License/MIT License/ universally, as they're the same thing.

Fixes #8681.

More cleanup in locale kit, this time regarding namespaces.

* it's bad practice to do a 'using <namespace>' in a header, as that
is very likely to have unintended effects, so drop those from a couple
of private Locale headers
* adjust files all over the locale kit in order to fix the problems
(by explicitly importing the required classes in the implementation
files)

* Use const references instead of pointers for the read from/write to
attribute/resource method in locale kit catalogs
* Only load the embedded catalog if nothing else was found, so it can easily
be overridden
* Change the resource type to 'CADA' (CAtalog DAta) for embedded catalogs, and
use a hash of the language code as the resource ID. This allows multiple
languages to be stored in the same file and does not interfere with the user
storing his own BMessages as resources.

Closing #6721: avoid unescaping when linking catalogs together
* add SetRawString() to both implementations of DefaultCatalog which sets
the translated string as given
* use SetRawString() in both (standard- and build-)versions of linkcatkeys

* updated ICU build packages with newer builds that try a bit harder to avoid
warnings and incorporate some of the ICU-patches we had in our repo before
we upgraded to 4.4.1
* fixed remaining warnings when building locale kit
* activated EnableWerror for locale kit
* added 'Unicode' license, which is the second license in use by ICU

* reintegrated gsoc-locale-kit branch into trunk - there's more
work to do, but it's about time to give this code more exposure.
