mod_auth_vas4-4.0.1

• The -u option now works with -n in the http-get/get binary.
• Because bug fix #831 depended on a QAS 4.0.3.177 api change this broke backwards compatibility. Added a new way to check for existing symbols in the loaded library to validate that a function exists, if not it will fall back to the old method. In regards to #831 if QAS 4.0.3.177+ is being used the new method vas_gss_auth_with_server_id will be used, all versions prior to this will use vas_gss_auth.
• MAV package name can now be partially set from an environment variable MAVPACKAGENAME. The PolyPackage build system will look at this variable (as defined in mav.pp.in) to help determine the final name of the built MAV package.
• Fixed misquoted CFLAGS & LDFLAGS tests.
• Utilized a new method that was added in QAS 4.0.3.177 api called vas_gss_auth_with_server_id. New method allows us to pass in an already established vas_id_t that represents our server_id with the correct path already set for a custom keytab path that is set by AuthVasKeytabFile. Bug fix #831. Related to QAS bug 27613
• Fixed name for loading the MAV4 module
• Updated test-cache to work with http 2.4 - Bug fix 830
• Changed module name from mod_auth_vas to mod_auth_vas4 and AuthType is now VAS4
