Ard Biesheuvel cd8ff8fdda Ovmf/Xen: move XenBusDxe hypercall code to separate library
This moves all of the Xen hypercall code that was private to XenBusDxe
to a new library class XenHypercallLib. This will allow us to reimplement
it for ARM, and to export the Xen hypercall functionality to other parts
of the code, such as a Xen console SerialPortLib driver.

Ard Biesheuvel bbc3758ab5 Ovmf/Xen: refactor XenBusDxe hypercall implementation
This refactors the Xen hypercall implementation that is part of the
XenBusDxe driver, in preparation of splitting it off entirely into
a XenHypercallLib library. This involves:
- removing the dependency on XENBUS_DEVICE* pointers in the XenHypercall()
  prototypes
- moving the discovered hyperpage address to a global variable
- moving XenGetSharedInfoPage() to its only user XenBusDxe.c (the shared info
  page is not strictly part of the Xen hypercall interface, and is not used
  by other expected users of XenHypercallLib such as the Xen console version
  of SerialPortLib
- reimplement XenHypercall2() in C and move the indexing of the hyperpage
  there; the existing asm implementations are renamed to __XenHypercall2() and
  invoked from the new C implementation.

Anthony PERARD f1259bba36 OvmfPkg/XenBusDxe: Add Event Channel Notify.
This first function is used to notify the other side that there is
something to do. The other side is another Xen domain.

Change in V4:
- Replace the license by the commonly used file header text.

Change in V3:
- Return error code from hypercall instead of ASSERT for
  XenEventChannelNotify
- moving event_channel.h to this patch.

Change in V2:
- file header
- coding style
- adding comment to functions
- Licenses

License: This patch adds event_channel.h which is under MIT licence.
