From: Nikunj A. Dadhania nik...@linux.vnet.ibm.com
This patch adds a structure virMemoryParameter, it contains the name of the
parameter and the type of the parameter along with a union.
v4:
+ Add unsigned int flags to the public api for future extensions
v3:
+ Protoype for virDomainGetMemoryParameters and dummy python binding.
v2:
+ Includes dummy python bindings for the library to build cleanly.
+ Define string constants like hard_limit, etc.
+ re-order this patch.
