PUP-1244 yum provider - added method to parse epoch/version/release string to hash. added skeleton of version (evr) comparison function
PUP-1244 stub out rpmvercmp method to be ported over from rpm's C implementation
PUP-1244 add yum_compareEVR method to do version comparison the way yum does it, along with compare_values method that calls rpmvercmp
PUP-1244 add spec for newly added yum methods to parse [e]v[r] strings and compare versions
PUP-1244 pull in upstream tests for new rpmvercmp method
PUP-1244 implemnted rpmvercmp to mirror RPM's own C implementation of this function
continuing work... seeing some errors in the yum testing. Need to stub out methods so it's clear where the problem is.
