a1e641a550 xen: make direct call when there is only one subdriver 
No need to use a for loop if we know there is exactly one client.
Found by:

for f in $(sed -n 's/.*Drv[^ ]* \([^;]*\);.*/\1/p' src/xen/xen_driver.h)
do
  git grep "\(\.\|->\)$f\b" src/xen
done | cat

and looking through the resulting list to see which callback struct
members are used exactly once.  The next patch will ensure that we
don't reintroduce uses of these callbacks.

* src/xen/xen_driver.c (xenUnifiedClose): Call close
unconditionally, to match xenUnifiedOpen.
(xenUnifiedNodeGetInfo, xenUnifiedDomainCreateXML)
(xenUnifiedDomainSave, xenUnifiedDomainRestore)
(xenUnifiedDomainCoreDump, xenUnifiedDomainUpdateDeviceFlags):
Make direct call to lone implementation.
* src/xen/xend_internal.h (xenDaemonDomainCoreDump)
(xenDaemonUpdateDeviceFlags, xenDaemonCreateXML): Add prototypes.
* src/xen/xend_internal.c (xenDaemonDomainCoreDump)
(xenDaemonUpdateDeviceFlags, xenDaemonCreateXML): Export.

934fdcb3c5 build: fix bugs with destroyFlags patches 
Build failure on xenapi_driver from compiler warnings (flags was unused).

Build failure on xen (incorrect number of arguments).  And in fixing
that, I obeyed the comments of struct xenUnifiedDriver that state
that we want to minimize the number of callback functions in that
struct, not add to it.

* src/xen/xen_driver.c (xenUnifiedDomainDestroyFlags): Use correct
arguments.
(xenUnifiedDomainDestroy): Simplify.
* src/xen/xen_driver.h (xenUnifiedDriver): Remove unused callback.
* src/xen/xen_hypervisor.c (xenHypervisorDestroyDomain): Likewise.

9817604afc Rename internal DumpXML functions to GetXMLDesc 
This matches the public API and helps to get rid of some special
case code in the remote generator.

Rename driver API functions and XDR protocol structs.

No functional change included outside of the remote generator.

e443a00312 vcpu: improve support for setting xen vcpu counts 
Tested with RHEL 5.6 (xendConfigVersion 2, where xend_internal
controls live domains and xm_internal controls inactive domains).

controls everything).

more flags.

2659b3f5aa Fix logic in xenUnifiedNumOfDomains to match xenUnifiedListDomains 
The xenUnifiedNumOfDomains and xenUnifiedListDomains methods work
together as a pair, so it is critical they both apply the same
logic. With the current mis-matched logic it is possible to sometimes
get into a state when you miss certain active guests.

* src/xen/xen_driver.c: Change xenUnifiedNumOfDomains ordering to
  match xenUnifiedListDomains.
