command does, but worse.
o Remove the obscure proc command, because it does what the thread
command does, but not unambigously.
o Move the PID to the extra thread info, where it makes sense and
where it doesn't confuse users. The extra thread info holds some
process information, to which the PID belongs.
o Implement the to_find_new_threads target method by having it call
the target beneath us if we're not using KVM. This makes sure that
new threads are found when using the remote target.
o Fix various core dump scenarios:
- Implement the to_files_info target method. Previously the
'info target' command would cause a NULL pointer dereference.
- Don't assume there's a current thread. We're not initialized
in all cases. This prevents a NULL pointer dereference.
- When we're not ussing KVM, have the to_xfer_memory target
method call the target beneath us. This avoids calling into
KVM with a NULL pointer.

static.
o Register a function with atexit(3) to close the KVM object if
we have one open.
o Show the unread portion of the kernel's message buffer before
presenting the prompt. It's bound to provide some useful info.
o Don't call kgdb_target() twice. It results in having all threads
listed twice.

in future calls, so we can't free it here. The right place to free the
buffer would be to be after kvm_close(), but we don't do that yet. A
static buffer would work too.

Display PID and process name as a part of the 'info threads' output, TIDs
alone are too confusing. Introduce new commmands 'tid <tid>' and 'proc <pid>'
to accompany gdb's default 'thread <thread num>' to make the task of switching
between different contexts easier.
library. As the value suggests, this allows the library to be built repeatably;
without this flag, gcc uses a random value in its parsing.
Since the random seed is only used when handling files which do not have any
externally-visible symbols, this change is not needed for any other libraries
in the FreeBSD base system.

For corefiles, we rely on gdb internals to do this, and it uses the
pid as an index, rather than the lwpid, so previously, backtraces
for multithreaded core files wasn't working correctly. For processes,
we currently use ptrace directly, so fixup that code to also use
the pid directly.

Implement the -a option to bump the annotation_level. This improves
the Emacs gud behaviour. You can now supply the following function
(defun gud-gdb-massage-args (file args) (cons "-a" args))
(e.g. by evaluating it from the *scratch* buffer) and get the normal
jump to the source window when browsing the stack.
We should probably eventually supply our own kgdb submode to gud.el.

changes, start on a new line. Insertion of a filename will keep the
diff limited to the block of filenames that have the same first letter
instead of creating a huge diff. While here, move remote.c after the
remote-*.c files and move tui.c after the tui-*.c files. This matches
the order of ls(1) and makes it easier to compare object files created
by a stock gdb(1) build with the list of files we have here.
This is a non-functional change only.
