[libvirt] [PATCH v2 00/11] Implement memory control api

[Nikunj A. Dadhania]

Changelog from v1:
  * Patch re-ordering for compilation
  * Folded python bindings changes to patch 01
  * Added defines for string constants for memory tunables
  * Typo fix: min_guarantee
  * Moved initialization of function pointers in driver.h patch

This patch series implement public api for controlling various memory tunables
exported by the OS. This is based on the following RFC[1].

* Implement virDomainSetMemoryParameters api
* Provide implementation for remote, QEmu and LXC drivers
* Enable memory controller support fro QEmu
* virsh command for runtime changes to the memory parameters
* Domain configuration parsing for memory control parameters
* Cgroup memory controller code for memory hard_limit/soft_limit, swap
  hard_limit 

To Do
* Python bindings is just a place holder, need to implement
* virDomainGetMemoryParameters
