dc78598a0f Claim frames corresponding to tl(0|1)_intr and tl0_trap as well. I 
think that's the lot, but it's hard to understand the exception code
by mere glancing at it.

78af1d5d26 Unwind across intrframes as well. While here, better handle bottom of 
stack by claiming the frame when the IP is 0. It's a bit of a kluge,
but avoids screens full of bogus frames.

35f38699dc Unwind across trap frames. This adds most of the meat. The sniffer 
just needs to be taught about all the other entry points and the
unwinder needs to be taught about the frame variation between them.

c67d07416a Add a kluge to allow kgdb(1) to inject its own frame sniffer in the 
list of frame sniffers so that trapframes can be detected. The kluge
is needed because this version of gdb only supports appending a
sniffer to the list of sniffers and the moment kgdb gets a chance to
add its own frame sniffer, the target's default frame sniffer is
already in the list. Since the default frame sniffer claims any
frame thrown at it, kgdb's frame sniffer never gets to smell (a
process much akin to tasting, but with lesser chance of hurling :-)

This commit adds dummy frame sniffers that never claim a frame and
as such don't fix anything yet. However, we now have frame sniffers
and they are being called, so it's just a matter of adding meat to
the bones and we'll be able to properly unwind across trapframes.

688deacdfa o Remove the obscure tid command, because it does what the thread 
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.

9ca14a4113 o As mentioned in the previous commit: make the KVM error buffer 
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.

8015e78d5d kvm_openfiles() uses the supplied buffer for storing error messages 
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.
