buffers: major cleanup and improvements
This patch introduces following changes: - deprecated free lists which are not used and not compatible with external buffer managers (i.e. DPDK) - introduces native support for per-numa buffer pools - significantly improves performance of buffer alloc and free Change-Id: I4a8e723ae47056717afd6cac0efe87cb731b5be7 Signed-off-by: Damjan Marion <damarion@cisco.com>
