Without this the use of uc0 is racy between the current thread and the
thread that owns it and will delete it.
This also ensures we don't trigger a read event on the session before
moving it to the right thread and notifying the application.

This change adds packet headers for each packet in a UDPC connection. This
changes the semantic of UDPC from an unreliable, unordered stream of bytes to an
unreliable, unordered sequence of packets.

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)

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

- server_rx/tx_fifo to rx/tx_fifo
- stream_session.h to session_types.h

- adds session layer support for datagram based protocols
- updates udp to work in pure connectionless and datagram mode. The
existing connected mode is now 'accessible' for apps as a dummy UDPC,
as in, connected udp, protocol.
- updates udp_echo, echo client, echo server code to work in datagram
mode.

Applications are now provided the option to select the namespace they
are to be attached to and the scope of their attachement. Application
namespaces are meant to:
1) constrain the scope of communication through the network by
association with source interfaces and/or fib tables that provide the
source ips to be used and limit the scope of routing
2) provide a namespace local scope to session layer communication, as
opposed to the global scope provided by 1). That is, sessions can be
established without assistance from transport and network layers.
Albeit, zero/local-host ip addresses must still be provided in session
establishment messages due to existing application idiosyncrasies. This
mode of communication uses shared-memory fifos (cut-through sessions)
exclusively.
If applications request no namespace, they are assigned to the default
one, which at its turn uses the default fib. Applications can request
access to both local and global scopes for a namespace. If no scope is
specified, session layer defaults to the global one.
When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY)
binds are converted to binds to the requested interface.

This patch deprecates stack-based thread identification,
Also removes requirement that thread stacks are adjacent.
Finally, possibly annoying for some folks, it renames
all occurences of cpu_index and cpu_number with thread
index. Using word "cpu" is misleading here as thread can
be migrated ti different CPU, and also it is not related
to linux cpu index.
