Introduced cmake options for specifying the desired ABI version.
ABI version affects library soname and include path (include/c++/vN).
Baked ABI version into the headers (autogenerated __config_version) so that, ex. with -I/usr/include/c++/v2 you get major abi version=2 w/o additional -D settings.

Clang support for selecting vN include path is coming as a separate change.
