Commit 824dcaff was a regression (thankfully unreleased) for any
client code that used 'struct _virSchedParameter' directly rather
than the preferred virSchedParameter typedef. Adding a #define
avoids even that API change, while rearranging the file makes it
clear what the old vs. new API is.
* include/libvirt/libvirt.h.in: Rearrange older names to the
bottom and improve documentation on preferred names.
(virDomainGetSchedulerParameters, virDomainSetSchedulerParameters)
(virDomainSetSchedulerParametersFlags)
(virDomainSetBlkioParameters, virDomainGetBlkioParameters)
(virDomainSetMemoryParameters, virDomainGetMemoryParameters):
Use newer type names.
* python/libvirt-override.c: Adjust code generation to cope.
Suggested by Daniel P. Berrange.
