Andrew Burgess 2c91540aff gdbserver: add vFile:lstat packet support
In the following commits I added the target_fileio_stat function, and
the target_ops::fileio_stat member function:

  * 08a115cc1c gdb: add target_fileio_stat, but no implementations yet
  * 3055e3d2f1 gdb: add GDB side target_ops::fileio_stat implementation
  * 6d45af96ea gdbserver: add gdbserver support for vFile::stat packet
  * 22836ca885 gdb: check for multiple matching build-id files

Unfortunately I messed up, despite being called 'stat' these function
actually performed an 'lstat'.  The 'lstat' is the correct (required)
implementation, it's the naming that is wrong.

In the previous commit I fixed the naming within GDB, renaming 'stat'
to 'lstat' throughout.

However, in order to support target_fileio_stat (as was) on remote
targets, the above patches added the vFile:stat packet, which actually
performed an 'lstat' call.  This is really quite unfortunate, and I'd
like to do as much as I can to try and clean up this mess.  But I'm
mindful that changing packets is not really the done thing.

So, this commit doesn't change anything.

Instead, this commit adds vFile:lstat as a new packet.

Currently, this packet is handled identically as vFile:stat, the
packet performs an 'lstat' call.

I then update GDB to send the new vFile:lstat instead of vFile:stat
for the remote_target::fileio_lstat implementation.

After this commit GDB will never send the vFile:stat packet.

However, I have retained the 'set remote hostio-stat-packet' control
flag, just in case someone was trying to set this somewhere.

Then there's one test in the testsuite which used to disable the
vFile:stat packet, that test is updated to now disable vFile:lstat.

There's a new test that does a more direct test of vFile:lstat.  This
new test can be extended to also test vFile:stat, but that is left for
the next commit.

And so, after this commit, GDB sends the new vFile:lstat packet in
order to implement target_ops::fileio_lstat.  The new packet is more
clearly documented than vFile:stat is.  But critically, this change
doesn't risk breaking any other clients or servers that implement
GDB's remote protocol.

		   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
