Introduce first version of TCP code.
Supported functionality:
- open/close
- listen/accept/connect
- send/recv
In order to achieve that libtle_udp library was
reworked into libtle_l4p library that supports
both TCP and UDP protocols.
New libtle_timer library was introduced
(thanks to Cisco guys and Dave Barach <dbarach@cisco.com>
for sharing their timer code with us).
Sample application was also reworked significantly
to support both TCP and UDP traffic handling.
New UT were introduced.
