Subject: Implement support for versioning and release engineering procedures -
 version 1.2.5.a1 Instead of changing configure.ac AC_INIT for each version
 change, there is a new file - VERSION.sh.  This file also contains support
 for creating version numbers for pre-releases, and pre-release strings
 containing git commit hashes. One of the complications is that AC_INIT does
 not allow you to override the version and package tarname fields.  We can
 override them after the fact everywhere except in config.h.  AC_INIT defines
 the following which we would like to override but cannot: PACKAGE_VERSION
 PACKAGE_TARNAME PACKAGE_STRING PACKAGE_BUGREPORT Instead, we define DS_
 versions of these e.g. DS_PACKAGE_VERSION etc. and make these available with
 AC_DEFINE(DS_PACKAGE_VERSION,...) etc. As an extra added precaution, we
 undefine these in Makefile.am like this: DS_DEFINES = ... \ 
 -UPACKAGE_VERSION -UPACKAGE_TARNAME -UPACKAGE_STRING -UPACKAGE_BUGREPORT If
 someone tries to use PACKAGE_VERSION in C code, they will not be able to, and
 will have to use DS_PACKAGE_VERSION instead.  All of the DS code that used
 PACKAGE_VERSION has been changed to use DS_PACKAGE_VERSION instead. There is
 a new make target - git-archive - as a convenience for creating source
 tarballs from git.  By default, the source archive will be placed in the
 build directory - you can specify SRCDISTDIR=/path/to/SOURCES to use an
 alternate dir (e.g. make SRCDISTDIR=/path/to/rpmbuild/SOURCES git-archive to
 make a source tarball for rpmbuild) configure will print the branded package
 name and version Reviewed by: nkinder (Thanks!)
