uselocale now attempts to create a backend and a databrige.
If the attempt fails due to a missing libroot-addon-icu, uselocale
does nothing (to support applications calling uselocale during
startup to enforce the C locale).
Else, uselocale will fail with ENOMEM.
LocaleBackend::CreateBackend() has been modified to return a status_t
that indicates whether NULL is returned due to out of memory (B_NO_MEMORY)
or due to being unable to load the ICU addon (B_MISSING_LIBRARY).
