Type: feature
To avoid excessive bursts, pacer must be provided with an estimated rtt
for the connection. That's used to compute an idle timeout, i.e., time
after which the bucket is reset to 1 mtu due to inactivity. For now,
idle timeout is computed as 5% of the rtt.

Type: feature
Add option to always compile in debugging infra. Debug verbosity can be
controlled via configuration updatable via cli. Compile time inclusion
and configuration of event logging verbosity is still available in order
to minimize event logging impact.

Type: feature
First cut implementation with limited testing. The feature is not
enabled by default and the expectation is that cc algorithms will enable
it on demand.

Fifos can use multiple memory chunks for simple read/write operations.
Adding/removing chunks after assignment not yet supported.

Problems Addressed:
- Contention of cursize by producer and consumer.
- Reduce the no of modulo operations.
Changes:
- Synchronization between producer and consumer changed from cursize
to head and tail indexes
Implications: reduces the usable size of fifo by 1.
- Using weaker memory ordering C++11 atomics to access head and tail
based on producer and consumer role.
- Head and tail indexes are unsigned 32 bit integers. Additions and
subtraction on them are implicit 32 bit Modulo operation.
- Adding weaker memory ordering variants of max_enq, max_deq, is_empty
and is_full Using them appropriately in all places.
Perfomance improvement (iperf3 via Hoststack):
iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86)
~6%(256 rxd/txd) - ~11%(2048 rxd/txd)

- avoid changing snd_nxt when doing fast retransmits
- use snd_una_max only to keep track of the max seq number sent
- simplify future ack testing

Make app-listener the handle for app listens. Consequently transport and
local listen sessions are now associated to the app-listener.

Rename core data structures. This will break compatibility for out of
tree builtin apps.
- stream_session_t to session_t
- server_rx/tx_fifo to rx/tx_fifo
- stream_session.h to session_types.h
- update copyright

Move the tcp unit test to the plugin
Add a bihash unit test and a "make test" program to call it
Adjust framework.py to load the plugin, which is disabled by default
