[IB] uverbs: ABI-breaking fixes for userspace verbs
Introduce new userspace verbs ABI version 3. This eliminates some unneeded commands, and adds support for user-created completion channels. This cleans up problems with file leaks on error paths, and also makes sure that file descriptors are always installed into the correct process. Signed-off-by: Roland Dreier <rolandd@cisco.com>
