[PATCH] buildhistory-diff: add ability to report version changes

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Add a -v/--report-ver option to report changes in PKGE/PKGV/PKGR even
if the value is the same as the default from PE/PV/PR.

Also add a -a/--report-all option to report all changes instead of just
the default significant ones.
