Markus Metzger b674665b51 gdb, btrace: switch threads in remote_btrace_maybe_reopen()
In remote_btrace_maybe_reopen() we iterate over threads and use
set_general_thread() to set the thread from which to transfer the btrace
configuration.

This sets the remote general thread but does not affect inferior_ptid.  On
the xfer request later on, remote_target::xfer_partial() again sets the
remote general thread to inferior_ptid, overwriting what
remote_btrace_maybe_reopen() had done.

In one case, this led to inferior_ptid being null_ptid when we tried to
enable tracing on a newly created thread inside a newly created process
during attach.

This, in turn, led to find_inferior_pid() asserting when we iterated over
threads in record_btrace_is_replaying(), which was called from
record_btrace_target::xfer_partial() when reading the btrace configuration
of the new thread to check whether it was already being recorded.

The bug was exposed by

    0618ae4149 gdb: optimize all_matching_threads_iterator

and found by

    FAIL: gdb.btrace/enable-new-thread.exp: ... (GDB internal error)

Use switch_to_thread() in remote_btrace_maybe_reopen().

		   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.
