switching to clang in base.
add COMPILER_LIBCXX where c++abi is used. there will be some "Extra"s but
this is the simplest way to use c++abi on base=clang and estdc++ on base=gcc
arches.
macppc still stays on using gcc due to too many problems there.
On amd64 and i386 now use the non-fragile-abi.
Now that allows on amd64 and i386 to use newer objective-c 2.0
features.
Some new features:
* now possible to rate songs
* new Playlist Inspector
* allows to configure a random feed to the playlist
* random feed can be based on the song ratings
* other minor fixes and additions
* new dependency to x11/gnustep/sqlclient

gnustep-base doesn't need to install the compatibility layer anymore,
which requires a major lib bump.
Bump revision of all dependent packages, and remove double REVISION
in webservices
