fuse-bridge: update to fuse protocol minor version 16 (Linux)
7.14 - Splice write support to fuse device node. No gluster changes required besides header update. 7.15 - Store/retrieve notification support. No gluster changes required besides header update. 7.16 - BATCH_FORGET request support. Implement a handler for BATCH_FORGET requests and update the header. - Updated ioctl() ABI. No gluster changes required besides header update.
