*	lib: Support for rudimentary retransmission	Dimitri Staessens	2018-07-27	1	-232/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This adds rudimentary support for sending and processing acknowledgments and doing retransmission. It replaces the generic timerwheel with a specific one for retransmission. This is currently a fixed wheel allowing retransmissions to be scheduled up to about 32 seconds into the future. It currently has an 8ms resolution. This could be made configurable in the future. Failures of the flow (i.e. rtx not working) are indicated by the rxmwheel_move() function returning a fd. This is currently not yet handled (maybe just setting the state of the flow to FLOWDOWN is a better solution). The shm_rdrbuff tracks the number of users of a du_buff. One user is the full stack, each retransmission will increment the refs counter (which effectively acts as a semaphore). The refs counter is decremented when a packet is acked. The du_buff is only allowed to be removed if there is only one user left (the "stack"). When a packet is retransmitted, it is copied in the rdrbuff. This is to ensure integrity of the packet when multiple layers do retransmission and it is passed down the stack again.

*	lib: Fix assertions in timerwheel0.9.6	Sander Vrijders	2018-01-29	1	-2/+2
\| \| \| \| \| \| \| \|	The previous commit only fixed the issue for release builds. This fixes it for debug builds as well. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>

*	lib: Make timerwheel a passive component	Sander Vrijders	2017-08-22	1	-150/+8
\| \| \| \| \| \|	This turns the timerwheel into a passive component since it is used by application using the library. The user of the timerwheel now has to call timerwheel_move to advance the timerwheel.
*	build: Revise the build system	dimitri staessens	2017-08-21	1	-1/+4
\| \| \| \| \| \| \| \| \| \|	This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.
*	lib: Add basic FRCT mechanisms	Sander Vrijders	2017-08-17	1	-0/+371
	This adds the basic FRCT mechanisms to the library. Upon flow alloc or accept an FRCT instance is now created and used when reading or writing to the flow. The timerwheel has been refactored to allow recharging timers and removing them and is now part of the library. The first SDU sent over the connection has the DRF set and this initializes the connection. Sender and receiver inactivity timers are added.
