[PATCH 1/2] uapi/fuse.h: Add message definitions for O_TMPFILE

[Chirantan Ekbote <chirantan@xxxxxxxxxxxx>]

Add the fuse_tmpfile_in struct and the FUSE_TMPFILE opcode. Like other
operations that create new entries, the server should reply to a
FUSE_TMPFILE message with a fuse_entry_out for the newly created entry.
