causing problems for a few people:
1. HVM guests can now have page directories with unknown
back pointers (I think this is the cause of problems that
Jun Nakajima was seeing).
2. L1 pagetable pinning requests are no longer ignored (may
be the cause of problems Joe Bonasera was seeing).
3. The PGT_va_mutable flag has been reintroduced, but for
L1 pagetables only.

output. Refactor the code slightly to allow more user-specified
control. This is done by adding a parallel
xc_domain_dumpcore_via_callback, which allows the specification of a
callback routine and an opaque argument block. The existing dumpcore
routine is modified to use the callback for all write operations and
to turn the single seek into a small write (it's for page alignment).

VMX guest, the Xen hyper visor has no handling of it resulting in a
bug(). This patch handles such VMX instructions from the guest returning
invalid opcode to the guest. Also the macro VMX_INVALID_ERROR_CODE is
renamed to the more meaningful VMX_DELIVER_NO_ERROR_CODE.

interface parameters are always used, so there's no need for them to be named
parameters with defaults.
Remove unused httpserver.getRoot and getPort, and simplify the main request
loop. This means that socket errors do not have to be squelched.
Coalesce the two identical bind methods, one in UnixHttpServer, one in
UnixListener. Fix this bind method to set the permissions on the socket
explicitly. This closes a security hole, and fixes the intermittent failure
of xm-test/06_list_nonroot.test.

occurs in xend. Currently, the parsing is hard-coded; it expects that
the desired number is on the first line. My patch is more robust; it
lets values be retrieved by a label. It also exposes a few functions to
retrieve the current allocation and the target allocation.
By abstracting this a little better, I'll be able to address a few
other issues in subsequent patches. Mostly, this allows for better
error checking and guidance for the user. For example, by exposing
get_dom0_current_alloc(), we can (elsewhere, in a later patch) calculate
how large of a VM could potentially be started. This is useful, as it
lets simple VM-creation GUIs guide the user towards reasonable memory
values for new VMs.

usage of the underlying domain building routines in "file-challenged"

Specifically, xc_linux_build_mem is the buffer oriented version of the
file-oriented xc_linux_build. Likewise, xc_hvm_build_mem is the
buffer oriented analog of the file based xc_hvm_build.
