- cache and reuse tcp options and rcv_wnd for session layer tx bursts
- avoid reading/setting total_length_not_including_first_buffer. It's
part of a buffer's second cache line so it comes at a "cost".

- sprinkle statics for functions
- move some inlines from header files to corresponding .c files
- replace some always_inlines with statics where inlining is not
performance critical

Because it avoids pool putting/getting the timer, this function is
somewhat faster than stopping and restarting a timer.

- Cleanup session state after last ack and avoid using a cleanup timer.
- Change session cleanup to free the session as opposed to waiting for
delete notify.
- When in close-wait, postpone sending the fin on close until all
outstanding data has been sent.
- Don't flush rx fifo unless in closed state

- fix newreno cwnd computation
- reset snd_una_max on entering recovery
- accept acks beyond snd_nxt but less than snd_congestion when in
recovery
- avoid entering fast recovery multiple times when using sacks
- avoid as much as possible sending small segments when doing fast
retransmit
- more event logging

It consists of two main parts. First, add an application transport type
whereby applications can offer transport to other applications. For
instance, a tls app can offer transport services to other applications.
And second, a tls transport app that leverages the mbedtls library for
tls protocol implementation.

This consolidates builtin apps under session-apps folder. It also

This is a version of the VPP API generator in Python PLY. It supports
the existing language, and has a plugin architecture for generators.
Currently C and JSON are supported.
Changes:
- vl_api_version to option version = "major.minor.patch"
- enum support
- Added error checking and reporting
- import support (removed the C pre-processor)
- services (tying request/reply together)
Version:
option version = "1.0.0";
Enum:
enum colours {
RED,
BLUE = 50,
};
define foo {
vl_api_colours_t colours;
};
Services:
service {
rpc foo returns foo_reply;
rpc foo_dump returns stream foo_details;
rpc want_stats returns want_stats_reply
events ip4_counters, ip6_counters;
};
Future planned features:
- unions
- bool, text
- array support (including length)
- proto3 output plugin
- Refactor C/C++ generator as a plugin
- Refactor Java generator as a plugin

dbarach: clean up an annoying checkstyle issue: indent 2.2.10
(OpenSUSE version) and indent 2.2.11 (Ubuntu / CentOS versions) had an
artistic disagreement about ip_frag.c.

- compute session type out of transport and network protos
- make session, session lookup and session queue code network protocol
agnostic
This does not update the session layer to support non-ip network layer
