Simon Marchi 2189c31265 gdb: add remote_debug_printf
This is the next in the new-style debug macro series.

For this one, I decided to omit the function name from the "Sending packet" /
"Packet received" kind of prints, just because it's not very useful in that
context and hinders readability more than anything else.  This is completely
arbitrary.

This is with:

  [remote] putpkt_binary: Sending packet: $qTStatus#49...
  [remote] getpkt_or_notif_sane_1: Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::

and without:

  [remote] Sending packet: $qTStatus#49...
  [remote] Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::

A difference is that previously, the query packet and its reply would be
printed on the same line, like this:

  Sending packet: $qTStatus#49...Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::

Now, they are printed on two lines, since each remote_debug_printf{,_nofunc}
prints its own complete message including an end of line.  It's probably
a matter of taste, but I prefer the two-line version, it's easier to
follow, especially when the query packet is long.

As a result, lib/range-stepping-support.exp needs to be updated, as it
currently expects the vCont packet and the reply to be on the same line.
I think it's sufficient in that context to just expect the vCont packet
and not the reply, since the goal is just to count how many vCont;r GDB
sends.

gdb/ChangeLog:

	* remote.h (remote_debug_printf): New.
	(remote_debug_printf_nofunc): New.
	(REMOTE_SCOPED_DEBUG_ENTER_EXIT): New.
	* remote.c: Use above macros throughout file.

gdbsupport/ChangeLog:

	* common-debug.h (debug_prefixed_printf_cond_nofunc): New.
	* common-debug.c (debug_prefixed_vprintf): Handle a nullptr
	func.

gdb/testsuite/ChangeLog:

	* lib/range-stepping-support.exp (exec_cmd_expect_vCont_count):
	Adjust to "set debug remote" changes.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
