[PATCH] SUPPORT.md, MAINTAINERS: De-support qemu-xen-traditional

[Ian Jackson <iwj@xxxxxxxxxxxxxx>]

In 4.16 we changed to not build this by default.  I think it is now
time to explicitly desupport it, completely, in favour of Linux dm
stub domains.

 ### qemu-xen-traditional ###
 
 The Xen Project provides an old version of qemu with modifications
-which enable use as a device model stub domain.  The old version is
-normally selected by default only in a stub dm configuration, but it
-can be requested explicitly in other configurations, for example in
-`xl` with `device_model_version="QEMU_XEN_TRADITIONAL"`.

-    Status, Device Model Stub Domains: Supported, with caveats
-    Status, as host process device model: No security support, not recommended
+When device model stub domains are desired for the additional
+security, we recommend using a device model stub domain consisting of
+a modern qemu and a Linux kernel.
 
-qemu-xen-traditional is security supported only for those available
-devices which are supported for mainstream QEMU (see above), with
-trusted driver domains (see Device Model Stub Domains).
+    Status: Obsolete
