More console cleanups. The console ring now overwrites its tail when
it fills, rather than stop recording output. The guest serial output
is only allowed to half-fill the serial output buffer, and now
respects hypercall preemption requests.

Rationalise debugger stuff in the tree.
Within Xen itself, remove PDB references and fold into domu_debug.
When domu_debug hits a breakpoint, it pauses all vcpus of the domain
and raises VIRQ_DEBUGGER (not VIRQ_PDB). The debugger in domain0 can
either poll pause status or bind to VIRQ_DEBUGGER. Before debugging
a breakpointed domain the debugger should issue PAUSEDOMAIN itself, or
it is not guaranteed to see paused state of the domain!
Outside Xen there's a new dir tools/debugger, containing gdb, pdb and
a new library libxendebug (used by pdb). I also think the ptrace
functions in libxc also ought to be moved out: either to libxendebug
or to a new library libxenptrace.

[PATCH] xen-libxc-static-build.patch
Fix build of the static library.
As it was depending on an undefined objects variable (OBJS), its

Also optimize the depedency checking so we don't need a submake. Not
too great an optimization, but it makes it short :)

Cleaner GDT interface. Xen now reserves the last 2 pages of a full-size
(16 page) GDT. A guest can register a GDT with up to 7k entries. Xen
automatically makes the GDT up to max size with empty page mappings,
and turns page faults in that area to #GP(selector).

[PATCH] xen,tools: pincpu use vcpu and cpumap_t
The following patch updates the dom0 pincpu operation to read the VCPU
value from the xend interface rather than hard-coding the exec_domain to
0. This prevented pinning VCPUS other than 0 to a particular cpu. The
pincpu cpu argument is replaced with cpumap, a u64 bitmap representing
which CPUs a VCPU can use.
I added the number of VCPUS to the main xm list output and also included
a new sub-option to xm list to display the VCPU to CPU mapping. While
working on the pincpu code, I fixed an out-of-bounds indexing for the
pincpu operation that wasn't previously exposed since the
vcpu/exec_domain value was hard-coded to 0.
