There's no point producing a long chain of zeroes when the previously
calculated total value was zero. To guard against mistakenly skipping
non-zero individual fields, widen "sum" to "unsigned long long".

This table must not have got updated in quite a while; tmem_op for
example has managed to not only appear since then, but also disappear
again (adding a name for it nevertheless, to make more obvious that
something strange is going on if the slot would ever have a non-zero
value).
Also resolve arch_0 and arch_1 to more meaningful names on x86.

Current function has heavily overloaded semantics for the various
arguments. Separate out into more specific functions.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

On solaris mlock requires a page aligned address and mlock doesn't
ensure the pages won't minor page fault.

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.].
