Introduce common-debug.h

Browse Source 
This introduces common-debug.h.  This holds the functions debug_printf
and debug_vprintf, two functions that the common code can use to print
debugging messages.  Clients of the common code are expected to
implement debug_vprintf; a debug_vprintf function is written from
scratch for GDB, and gdbserver's existing debug_printf is repurposed
as debug_vprintf.

common/agent.c is changed to use debug_vprintf rather than
defining the macro DEBUG_AGENT depending on GDBSERVER.

nat/i386-dregs.c is changed to use the externally-implemented
debug_printf, rather than defining it itself.

	* common/common-defs.h: Include common-debug.h.
	* common/agent.c (debug_agent_printf): New function.
	(DEBUG_AGENT): Redefine.
	* nat/i386-dregs.c (debug_printf): Undefine.
