gdb: factor out debug_prefixed_printf_cond

Browse Source 
The same pattern happens often to define a "debug_printf" macro:

    #define displaced_debug_printf(fmt, ...) \
      do \
        { \
          if (debug_displaced) \
    	debug_prefixed_printf ("displaced", __func__, fmt, ##__VA_ARGS__); \
        } \
      while (0)

Move this pattern behind a helper macro, debug_prefixed_printf_cond and
update the existing macros to use it.

gdb/ChangeLog:

	* displaced-stepping.h (displaced_debug_printf): Use
	debug_prefixed_printf_cond.
	* dwarf2/read.c (dwarf_read_debug_printf): Likewise.
	(dwarf_read_debug_printf_v): Likewise.
	* infrun.h (infrun_debug_printf): Likewise.
	* linux-nat.c (linux_nat_debug_printf): Likewise.

gdbsupport/ChangeLog:

	* common-debug.h (debug_prefixed_printf_cond): New.
	* event-loop.h (event_loop_debug_printf): Use
	debug_prefixed_printf_cond.
