* irmd: new locking implementationdimitri staessens2016-05-161-175/+221
| | | | | | | This locking should be more consistent, It now has three locks, one guarding flows and port_id's, one guarding the registered apps and ipcps, and one guarding the overall state of the irmd. There are two additional mutexes guarding the condition variables.

|/ | | | | This takes a lock before notifying the IRMd of a new flow request, to avoid race conditions when trying to retrieve the fd by port-id.

| * lib: Fix header inclusionSander Vrijders2016-05-146-26/+28
| | | | | | | | | | | | This fixes wrong header inclusion that would make programs which are not developed within ouroboros fail upon compilation, since they would not find certain headers on their system.

| * | lib, ipcpd, irmd: Add QoS cube definitionSander Vrijders2016-05-1416-109/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the QoS cube definition, which is an enum to select which QoS is needed in the IPCP. An application has to use the qos_spec in qos.h to define what it needs. The IRMd will map this unto a qos cube definition. Some headers are now also no longer installed on the system, since they are only to be used within the irmd and ipcps.
