>Description:

The definitions of `key_t' in <sys/types.h> and <machine/console.h>
conflict when used in a C++ environment.

>How-To-Repeat:

Compile something that included both headers under C++.

In file included from bsdsrc/kbd.cc:29:
/usr/include/machine/console.h:151: conflicting types for `struct key_t'
/usr/include/sys/types.h:70: previous declaration as `typedef long int key_t'
bsdsrc/kbd.cc:127: warning: `int KbdIsConsole()' defined but not used
*** Error code 1

Stop.

>Fix:
	
struct key_t should perhaps renamed into something else.  It's only
used in syscons and its related utilities.  sys/types.h's key_t is
used by the SysV IPC implementation, and thus part of the API.
