Subject: Cache the host port like we cache the task port

This way we do not
need to call the kernel just to get the port.  Furthermore, we no
longer increase the reference count on every invocation of
`mach_host_self'.

* mach/mach/mach_traps.h (__mach_host_self, mach_host_self):
Protect declarations against the macro expansion.
* mach/mach_init.c (__mach_host_self_): New variable.
(mach_init): Initialize `__mach_host_self_'.
* mach/mach_init.h (__mach_host_self_): New declaration.
(__mach_host_self, mach_host_self): New macros.
* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start_cleanup):
Release reference.
