the length of the decompressed data because images have been observed which have
trailing junk.

1. platform_op -- used by dom0 kernel to perform actions on the
hardware platform (e.g., MTRR access, microcode update, platform
quirks, ...)
2. domctl -- used by management tools to control a specified domain
3. sysctl -- used by management tools for system-wide actions
Benefits include more sensible factoring of actions to
hypercalls. Also allows tool compatibility to be tracked separately
from the dom0 kernel. The assumption is that it will be easier to
replace libxenctrl, libxenguest and Xen as a matched set if the
dom0 kernel does not need to be replaced too (e.g., because that
would require vendor revalidation).
From here on we hope to maintain dom0 kernel compatibility. This
promise is not extended to tool compatibility beyond the existing
guarantee that compatibility will not be broken within a three-level
stable release [3.0.2, 3.0.3, etc.].

move the shared info and grant table pfns into that block. This
allows us to remove the get_gnttablist dom0 op, and simplifies the
domain creation code slightly. Having the reserved block managed by
Xen may also make it slightly easier to handle the case where the
grant table needs to be extended at run time.

This is enough to get block devices to work.
Note that this involves assigning PFNs to the machine frames used for
the grant table structures. While I'm here, I also assigned a PFN to
the shared info frame.

Valgrind cannot see when a hypercall has initialised entries in a data
structure, so appropriate memsets have been placed before using dom0_op_t,
privcmd_hypercall_t, and a couple of miscellaneous blocks passed into this
layer. This initialises the block so that valgrind considers it to be valid,
but the data therein will be immediately overwritten by the hypercall, all
being well.
These changes are semantically neutral if -DVALGRIND is not set.

query a domain's current and maximum memory reservation. Also,
XENMEM_maximum_ram_page now returns the max_page directly,
rather than writing through a passed-in pointer.
Also, disable PAE in the default config (accidentally checked
in two changesets ago).

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.
