gfapi: object handle based API extensions
There is an ongoing effort to integrate NFS Ganesha ( https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of the file system back ends. Towards this we need extensions to gfapi that can handle object based operations. Meaning, instead of using full paths or relative paths from cwd, it is required that we can work with APIs, like the *at POSIX variants, to be able to create, lookup, open etc. files and directories. Hence the objects are the files or directories themselves and we give out handles to these objects that can be used for further operations. This code drop is an initial implementation of the proposed APIs. The new APIs are implemented as glfs_h_XXX variants in the file glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding onto inode references and doling these out as opaque/cookie type objects to the callers, to enable them to be used as handles in other operations. An fd based approach was considered, but due to the extra footprint that the fd structure and its counterparts would incur, this was dropped to take the approach of holding inode references themselves. Tested by extending glfsxmp.c to invoke and exercise the added APIs, and further tested with a reference integration of the same as an FSAL with NFS Ganesha.
