*	lib, ipcpd, irmd: fixes deallocation and fast path	dimitri staessens	2016-05-22	1	-18/+26
\| \| \| \| \| \|	The fast path has been rewritten to have certainty to read the correct flow. Deallocation will not release port_id's or fd's until they are explicitly released locally.
*	lib: allow parallel connections	dimitri staessens	2016-05-20	1	-4/+20
\| \| \| \| \| \|	dev.c: read now only reads an SDU if is is for the correct port_id shm_ap_rbuff: added a function peek() that returns the port_id of the tail.
*	lib: cleanup file descriptors for shared memory	dimitri staessens	2016-05-15	1	-0/+6
\| \| \| \| \|	cleanup of file descriptors for the shared memory. also adds a missing NULL check and some invalidation in dev.c
*	lib: shm_ap_rbuff: simplified file offsets	dimitri staessens	2016-05-15	1	-13/+9
\| \| \| \|	Used simpler pointer arithmetic to calculate the file offset pointers.
*	lib: dev.c: added locking	dimitri staessens	2016-05-14	1	-1/+3
\| \| \| \| \|	Locking is required for multi-threaded applications. Flows are locked separately. Read/Write locks are used for concurrent reads.
*	lib: shm_ap_rbuff: removed bad memory allocation	dimitri staessens	2016-05-14	1	-5/+4
\| \| \| \| \|	moved a malloc so there is no malloc/free when there is no data to be read from the shm_ap_rbuff.
*	lib: shm_ap_rbuff: small fixes	dimitri staessens	2016-05-12	1	-5/+0
\| \| \| \|	Unnecessary filename string removed. Formatting fix.
*	lib: dev: implementation of flow_cntl	dimitri staessens	2016-05-12	1	-0/+1
\| \| \| \| \|	allows setting the oflags to make flow_read and flow_write blocking or non-blocking (FLOW_O_NONBLOCK).
*	lib: fixed enormous memory leak in shm_ap_rbuff	dimitri staessens	2016-05-08	1	-3/+6
\| \| \| \|	thanks Sander ;)
*	lib: changed SHM_AP_RBUFF to SHM_AP_RBUFF_PREFIX	dimitri staessens	2016-05-08	1	-4/+4
\| \| \| \|	This better reflects the use as the pid is appended to that name.
*	irmd: flow allocation and fast path	dimitri staessens	2016-05-07	1	-0/+268
	This commit has a first implementation of flow allocation (the "slow path") and read/write (the "fast path") for ouroboros. It provides basic but unstable communications over the shared memory. It required a lot of changes all over the stack, and fixes a number of previously undetected issues. This PR still need heavy revision regarding data model, locking and cleanup. lib/dev: modifications to the API. It now uses an ap_init() call to set the AP name and sets the Instance ID to the pid of the process. It also binds the AP to the shared memory and creates tables for mappings in the fast path. A call to ap_fini() releases the resources. lib/shm_ap_rbuff: added ring buffer for data exchange between processes in the fast path. It passes an index in the shm_du_map. lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage collector added. Tests updated to new API. ipcpd/ipcp-data: removed everything related to flows, as these are universal for all ap's and kept in ap_data (dev.c), or similar structs for shim ipcps. shim-udp: added flow allocator and read/write functions and shm elements. irmd: revised data model and structures necessary for flow allocation. tools: echo updated to new dev.h API. messaging system was updated to comply with new flow allocation messages. All exchanges use pid and port_id to bootstrap the fast path.
