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.
