Keith Seitz 87f0e72047 Explicit locations: add UI features for CLI
This patch exposes explicit locations to the CLI user.  This enables
users to "explicitly" specify attributes of the breakpoint location
to avoid any ambiguity that might otherwise exist with linespecs.

The general syntax of explicit locations is:
-source SOURCE_FILENAME -line {+-}LINE -function FUNCTION_NAME
-label LABEL_NAME

Option names may be abbreviated, e.g., "-s SOURCE_FILENAME -li 3" and users
may use the completer with either options or values.

gdb/ChangeLog:

	* completer.c: Include location.h.
	(enum match_type): New enum.
	(location_completer): Rename to ...
	(linespec_completer): ... this.
	(collect_explicit_location_matches, backup_text_ptr)
	(explicit_location_completer): New functions.
	(location_completer): "New" function; handle linespec
	and explicit location completions.
	(complete_line_internal): Remove all location completer-specific
	handling.
	* linespec.c (linespec_lexer_lex_keyword, is_ada_operator)
	(find_toplevel_char): Export.
	(linespec_parse_line_offset): Export.
	Issue error if STRING is not numerical.

		   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.
