libsmbios soname bump

[Michael E Brown]

I have pushed libsmbios v2.0 to the fedora repository. All programs that
link against libsmbios will need to be rebuild. This release is mostly
API compatible with the old release. Some minor changes were made to fix
some C++ const-correctness issues.

Libsmbios v2 has several changes:

1) GCC 4.3 fixes
2) ABI-incompatible, thus the soname bumps to 2.
3) bumped the version to 2 to match the soname
4) RPM renames:
   libsmbios-bin  -> renamed to: smbios-utils
   libsmbios-libs -> renamed to: libsmbios
5) The API is largely unchanged. There were some C++ const-correctness
fixes to the API, so some small adjustments may need to be made to
client code.
6) The unused libsmbiosxml library was dropped.

The new RPMs still Provide: the old names, so things should continue to
work.
