Add "gid" slot to the images table for changing permission scheme from
only pid, to pid/gid like most other things in the testbed. Also add a "global" slot to denote images that are globally available to all projects (system images). The older "shared" attribute is now used to denote images that are shared within a project (available to all subgroups in the project). The migration path for existing DBs is given in the migrate file. Be sure to run those commands on an existing testbed or things will break! www/newimageid, www/newimageid_ez: A bunch of changes for shared/global attributes. Added a group menu to the form so users can create images in subgroups. Beefed up the Java code that constructs the path name to use the gid, shared, and global attributes of the form to give the user the best possible path that we can. Improved the pathname checking code so that we do not allow just any old path in case the user elects to disregard the path we carefully constructed for them. Also check the proj/group membership, and setup defaults for users that have permission in just one pid/gid to create images. libdb.in: Changed permission check in TBImageIDAccessCheck() to reflect shared/global attribute changes. os_load: Get rid of test that checked path of the image. The path checking is done in the web interface anyway, so why duplicate in 4 places. Other minor changes reflecting shared->global name change. Also note that images can come from the group directory now. create_image: Get rid of test that checked path of the image. The path checking is done in the web interface anyway, so why duplicate in 4 places. Also note that images can come from the group directory now. www/dbdefs: Changed permission check in TBImageIDAccessCheck() to reflect shared/global attribute changes. www/showimageid_list, www/showstuff: Minor global/shared attribute changes. www/menu: Change osids/imageids pointer to point to the image list, not the osid list. This is more reasonable for mere users who have access to the EZ form, and thus never really need to concern themselves with osids. www/editimageid: Add proper pathname checking. There were no checks at all before!
