Simon Marchi e242fd1249 Use -qualified flag when setting temporary breakpoint in start command
When using the "start" command, GDB puts a temporary breakpoint on the
"main" symbol (we literally invoke the tbreak command).  However, since
it does wild matching by default, it also puts a breakpoint on any C++
method or "main" function in a namespace.  For example, when debugging
GDB, it creates a total of 24 locations:

  (gdb) start
  Temporary breakpoint 1 at 0x198c1e9: main. (24 locations)

as there are a bunch of methods called main in the selftests, such as

  selftests::string_view::capacity_1::main()

If such method was called in the constructor of a global object, or a
function marked with the attribute "constructor", then we would stop at
the wrong place.  Also, this causes a few extra symtabs (those that
contain the "wrong" mains) to be expanded for nothing.

The dummiest, most straightforward solution is to add -qualified when
invoking tbreak.  With this patch, "start" creates a single-location
breakpoint, as expected.

I copied the start.exp test to start-cpp.exp and made it use a C++ test
file, which contains two main functions.  The new test verifies that the
output of "start" is the output we get when we set a single-location
breakpoint.

gdb/ChangeLog:

	* infcmd.c (run_command_1): Pass -qualified to tbreak when usind
	the "start" command.

gdb/testsuite/ChangeLog:

	* gdb.base/start-cpp.exp: New file.
	* gdb.base/start-cpp.cc: New file.

		   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.
