Hello,

The following set of patches came about when trying to fix the 32K limitation
with stub_xc_readconsolering() in the ocaml bindings.

Patch 1 is a hypervisor patch adding a new SYSCTL hypercall to query the size
of the console ring, which is fixed but otherwise inaccessible after boot.

Patches 2 thru 5 are tools patches:
 * Patch 2 adds a libxc function to use the new SYSCTL hypercall.
 * Patch 3 implements an alternative xc_readconsolering() to prevent bounce
   buffering.
 * Patch 4 uses the preceding patches to fix the implementation of
   stub_xc_readconsolering() in the ocaml bindings.
 * Patch 5 is a misc threading fix in the ocaml bindings, discovered when
   trying to fix the console functionality.

This patch set has been compile-tested on unstable, and functionally tested
via backport to 4.2 (which was only one whitespace fuzz issue and no code
change).
