Revision 1729654

The generated release artifacts for the 2.2 branch are now only the source and documentation artifacts, and do not include the release tooling like 'roll_release.sh'.  Those files are only used by the release manager, so shouldn't be in the source distribution. 

The LICENSE and NOTICE files also are no longer duplicated to 'LICENSE.TXT' and 'NOTICE.txt', as per Apache release recommendations.  

LICENSE and NOTICE files have been modified to reflect the fact that 'asm' and 'animal-sniffer' are no longer distributed with the source, but are downloaded at build time.
