Allow version comparison to contain epoch specifier

Adapting from RPM, follow the [epoch:]version[-release] syntax. We can also
borrow some of their parsing code for our purposes (thanks!).  Add some new
tests to our vercmp shell script tester for epoch comparisons, and then make
the code work with these newfangled epoch specifiers.
