Matthias Bolte 5fc663d8be esx: Fix and improve esxListAllDomains function 
Avoid requesting information such as identity or power state when it
is not necessary.

Lookup virtual machine list with the required fields (configStatus,
name, and config.uuid) to make esxVI_GetVirtualMachineIdentity work.

No need to call esxVI_GetNumberOfSnapshotTrees. rootSnapshotTreeList
can be tested for emptiness by checking it for NULL.

esxVI_LookupRootSnapshotTreeList already does the error reporting,
don't overwrite it.

Check if autostart is enabled at all before looking up the individual
autostart setting of a virtual machine.

Reorder VIR_EXPAND_N(doms, ndoms, 1) to avoid leaking the result of
the call to virGetDomain if VIR_EXPAND_N fails.

Replace VIR_EXPAND_N by VIR_RESIZE_N to avoid quadratic scaling, as in
the Hyper-V version of the function.

If virGetDomain fails it already reports an error, don't overwrite it
with an OOM error.

All items in doms up to the count-th one are valid, no need to double
check before freeing them.

Finally, don't leak autoStartDefaults and powerInfoList.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
