Paul Durrant 365aabb6e5 tools/libxendevicemodel: add xendevicemodel_modified_memory_bulk to map
Commit e3b93b3c59 "dmop: add xendevicemodel_modified_memory_bulk()" added
the implementation to the library almost 2 years ago, but the function
was not included in the map file, essentially making it useless. This
patch rectifies the situation.

Ian Jackson 4ed00f57f0 tools: libxendevicemodel: Restore symbol versions for 1.0
In 1462f9ea8f
"tools: libxendevicemodel: Provide xendevicemodel_shutdown"
we added a new version 1.1 to the symbol map and simply abolished
the old one.  That is quite wrong.

Instead, we should have left the 1.0 map alone and added a new version
which simply adds the new symbol.

Fix this.

Yu Zhang 306f164362 x86/ioreq server: add device model wrappers for new DMOP
A new device model wrapper is added for the newly introduced
DMOP - XEN_DMOP_map_mem_type_to_ioreq_server.

Since currently this DMOP only supports the emulation of write
operations, attempts to trigger the DMOP with values other than
XEN_DMOP_IOREQ_MEM_ACCESS_WRITE or 0(to unmap the ioreq server)
shall fail. The wrapper shall be updated once read operations
are also to be emulated in the future.

Also note currently this DMOP only supports one memory type,
and can be extended in the future to map multiple memory types
to multiple ioreq servers, e.g. mapping HVMMEM_ioreq_serverX to
ioreq server X, This wrapper shall be updated when such change
is made.

Paul Durrant 8ef5f344d0 tools/libxendevicemodel: add a call to restrict the handle
My recent patch [1] to the Linux privcmd module introduced a mechanism
to restrict an open file handle to subsequently only accept operations for
a specified domain.

This patch extends the libxendevicemodel API and make use of the
mechanism in the Linux-specific code to restrict operations on the
interface handle.

Paul Durrant 6902cb00e0 tools/libxendevicemodel: extract functions and add a compat layer
This patch extracts all functions resulting in a dm_op hypercall from
libxenctrl and moves them into libxendevicemodel. It also adds a compat
layer into libxenctrl, which can be selected by defining
XC_WANT_COMPAT_DEVICEMODEL_API to 1 before including xenctrl.h.

With this patch the core of libxendevicemodel still uses libxencall to
issue the dm_op hypercalls, but this is done by calling through code that
can be modified on a per-OS basis. A subsequent patch will add a Linux-
specific variant.

Paul Durrant b108240265 tools/libxendevicemodel: introduce the new library
The new xendevicemodel library is intended to be used by all Xen device
models such that the only hypercall that use will be the dm_op hypercall
added by commit 524a98c2.

This patch adds the boilerplate for the new library, with only open() and
close() entry points, and calls to those from libxenctrl in preparation
for the compat layer added by a subsequent patch.

[ Also: update MINIOS_UPSTREAM_REVISION and QEMU_TRADITIONAL_REVISION
  to the commits with the corresponding changes to those other trees
