Create a script to help update the version automatically (#5454)
* Create a script to help update the version automatically
* Update comment in the update_version script
* Update script to fix special handling for common.h and Makefile.am
* Revise update_version script to only update the other constants in common.h if it is a major release. Reset Makefile.am version to 17:0:0
