Daniel P. Berrangé 464a41bc0d qemu: delete methods which are no longer supported
The public API entry points will report VIR_ERR_NO_SUPPORT to the
caller when a driver does not provide an implementation of a particular
method.

When deleting methods, leaving the driver API entry point explicitly
set to NULL with an version range comment, allows the hvsupport.html
page to document when the AP was removed.
