Ian Wienand 2ba36cda79 Add vercmp function
The existing vercmp_numbers function only handles, as the name says,
numbers.  I noticed that "sort" has had a version sort for a long time
[1] and, rather than re-implement it badly, use this as a version of
vercmp that works a bit more naturally.

This is intended to be used in an "if" statement as in

  prog_ver=$(prog_ver --version | grep ...)
  if vercmp $prog_ver "<" 2.0; then
     ...
  fi

A test-case is added to test the basic features and some edge-cases.
