hurd: Use polymorphic port types to return some rights.
Currently, the RPC definitions of two procedures of the process
subsystem assume that the rights are created from a receive right.
Similarly, 'proc_getmsgport' assumes that the right is to be copied.
This needlessly limits the ability to relay the RPC in server code.
This fixes this. The protocol is unchanged, only the generated server
stubs assume an additional parameter for the type.
* hurd/process.defs (proc_getmsgport): Make 'msgport' parameter
polymorphic.
(proc_task2proc): Make 'proc' parameter polymorphic.
(proc_pid2proc): Likewise.
* hurd/process_reply.defs (proc_getmsgport): Likewise.
(proc_task2proc_reply): Likewise.
(proc_pid2proc_reply): Likewise.
* proc/info.c (S_proc_task2proc): Adapt server function.
(S_proc_pid2proc): Likewise.
* proc/msg.c (S_proc_getmsgport): Likewise.
