Modernize spec file to better match Fedora guidelines:
- remove unused %ver macro
- fix Release to avoid '-' character
- switch to newer recommendation for BuildRoot
- add Requires(post): /sbin/ldconfig and Requires(postun): /sbin/ldconfig
- split static libraries into new -devel-static package
- don't use %makeinstall
