Improvements to auto-deduction of VERSION
Improve version construction
Versioning debugging, unit-tests
pkgautoversion: deduce version from git; bunit.sh: bash unit test lib
Makefile updates for new binaries
EupsPkg: use native tar to do packaging (for speed)
pkgbuild: xmake verb, runs prep,config,build,install (but not eups_declare)
Store the URL of 'origin' to pkginfo, if $REPOSITORY points to local dir
EupsPkg: simplified pkgbuild, have pkgbuild be source on 'create'
pkgbuild: removed use_parallel_jobs() in favor of $NJOBS
