Pedro Alves 9c3a5d9319 linux-nat: Eliminate custom target_terminal_{inferior,ours}, stop using set_sigint_trap
This patch gets rid of linux-nat.c's custom
target_terminal_inferior/target_terminal_ours implementations.

The only remaining reason those overrides exist is to install
clear_sigint_trap in order to pass Ctrl-C/SIGINT to the inferior
process in case the inferior is not sharing GDB's terminal (and
target_wait was called without TARGET_WNOHANG).

However, I think that's better handled by QUIT / target_pass_ctrlc
nowadays.  Going that route avoids the issue with set_sigint_trap only
looking at the current inferior to know whether to override SIGINT or
not, which doesn't really work correctly with multi-inferior in the
picture.  Also centralizing on a single SIGINT handler as much as
possible seems better considering a future multi-target world.

Tested on x86-64 GNU/Linux.

gdb/ChangeLog:
2018-01-30  Pedro Alves  <palves@redhat.com>

	* linux-nat.c (wait_for_signal): New function.
	(wait_lwp, linux_nat_wait_1): Use it instead of calling sigsuspend
	directly.
	(async_terminal_is_ours)
	(linux_nat_terminal_inferior, linux_nat_terminal_ours): Delete.
	(linux_nat_add_target): Don't override
	to_terminal_inferior/to_terminal_ours.

		   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.
