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. gdb/ChangeLog: * common/common-debug.h: New file. * common/common-debug.c: Likewise. * debug.c: Likewise. * Makefile.in (SFILES): Add common/common-debug.c. (HFILES_NO_SRCDIR): Add common/common-debug.h. (COMMON_OBS): Add common-debug.o and debug.o. (common-debug.o): New rule. * 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. gdb/gdbserver/ChangeLog: * Makefile.in (SFILES): Add common/common-debug.c. (OBS): Add common-debug.o. (common-debug.o): New rule. * debug.h (debug_printf): Don't declare. * debug.c (debug_printf): Renamed and rewritten as... (debug_vprintf): New function.
