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.

This builds a libiberty just for gdbserver and arranges for gdbserver
to use it. I've tripped across the lack of libiberty in gdbserver at
least once, and I have seen other threads where it would have been
useful.
