Subject: ipc: undo manual inlining of `ipc_entry_X' functions

Today we can rely on the compiler to inline functions.  Undoing this
manual optimization is a first step to replace the IPC tables.

* ipc/mach_msg.c (mach_msg_trap): Undo the manual inlining of
`ipc_entry_lookup', `ipc_entry_dealloc', and `ipc_entry_get'.
* ipc/ipc_kmsg.c (ipc_kmsg_copyin_header, ipc_kmsg_copyout_header): Likewise.
* kern/exception.c (exception_raise): Likewise.
* kern/ipc_mig.c (fast_send_right_lookup): Likewise.
