We need to have a generic buffer API in order to efficiently transfer data between different subsystems. The first such case will be the Networking and Bluetooth subsystems where 6LoWPAN data will be passed back and forth. The needed API needs to provide enough flexibility for different buffer sizes as well as custom protocol-specific context data. The implementation offered in this patch follows the general design of the existing Networking and Bluetooth buffer implementations by using a backing array of buffer which is fed into a "free buffers" FIFO for management. The main difference is that the API allows specifying variable sized buffers for each created pool, as well as a minimum amount of "user data" that's allocated as part of each buffer. There's also an optional destroy callback that's e.g. useful for HCI flow control in Bluetooth (for notifying the controller of available buffers).
