Andrew Burgess ef8cf9093d gdb/python: Add new gdb.Value.bytes attribute
Add a gdb.Value.bytes attribute.  This attribute contains the bytes of
the value (assuming the complete bytes of the value are available).

If the bytes of the gdb.Value are not available then accessing this
attribute raises an exception.

The bytes object returned from gdb.Value.bytes is cached within GDB so
that the same bytes object is returned each time.  The bytes object is
created on-demand though to reduce unnecessary work.

For some values we can of course obtain the same information by
reading inferior memory based on gdb.Value.address and
gdb.Value.type.sizeof, however, not every value is in memory, so we
don't always have an address.

The gdb.Value.bytes attribute will convert any value to a bytes
object, so long as the contents are available.  The value can be one
created purely in Python code, the value could be in a register,
or (of course) the value could be in memory.

The Value.bytes attribute can also be assigned too.  Assigning to this
attribute is similar to calling Value.assign, the value of the
underlying value is updated within the inferior.  The value assigned
to Value.bytes must be a buffer which contains exactly the correct
number of bytes (i.e. unlike value creation, we don't allow oversized
buffers).

To support this assignment like behaviour I've factored out the core
of valpy_assign.  I've also updated convert_buffer_and_type_to_value
so that it can (for my use case) check the exact buffer length.

The restrictions for when the Value.bytes can or cannot be written too
are exactly the same as for Value.assign.

		   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.
