This required some changes to the framework:
* Init-/DeInitVCL is no longer done per individual test in BootstrapFixture, but
once per CppunitTest invocation in a new vclbootstrapprotector (similarly to
the exisiting unobootstrapprotector). CppunitTests that need VCL now need to
declare gb_CppunitTest_use_vcl.
* For things to work properly, the UNO component context needs to be disposed
from within DeInitVCL (cf. Desktop's Application::DeInit called from
DeInitVCL). The easiest solution was to introduce an
Application::setDeInitHook (where the hook is called from DeInitVCL)
specifically for vclbootstrapprotector to call.
* PythonTests don't (yet) call DeInitVCL; they still hook into
BootstrapFixture's original test_init functionality (to call InitVCL), and do
not make use of the vclbootstrapprotector.

Moved portions from module i18npool, all of former i18nisolang1 library
that now is i18nlangtag. Included are languagetag, isolang and mslangid.
This i18nlangtag code is now even used by module comphelper, so
disentangling i18npool and making this an own module was needed to not
create circular module dependencies.
