cbd4e90781 net/tcp: Rectified keepalive fix
Simplification of previous fix. Also fixes the case when new data should
be sent while a keepalive is not yet acked.

83745652c4 TCP-stack fix for stalled tcp sockets due to broken keepalive
Fixes an issue where tcp sockets with activated keepalives stalled and
were not properly closed. Poll would not indicate a POLLHUP and therefore
locks down the application.

* tcp_conn_s.tcp_conn_s & tcp_conn_s.keepintvl changed to uint32_t
  According RFC1122 keepidle MUST have a default of 2 hours.

66ef6d143a This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122.
Squashed commit of the following:

    net/tmp:  Rename the unacked field of the tcp connection structure to tx_unacked.  Too confusing with the implementation of delayed RX ACKs.

    net/tcp:  Initial implementation of TCP delayed ACKs.

    net/tcp:  Add delayed ACK configuration selection.  Rename tcp_ack() to tcp_synack().  It may or may not send a ACK.  It will always send SYN or SYN/ACK.

e59b26370d Squashed commit of the following:
Fix a few typo/compilation problems.
    net/:  Remove all CONFIG_NET_xxx_TCP_RECVWNDO configuration variables.  They were used only to initialize the d_recwndo of the network device structure which no longer exists.
    net/:  Remove the device TCP receive window field (d_recvwndo) from the device structure.  That value is no longer retained, but is calculated dynamically.
    Remove some dangling references to CONFIG_NET_TCP_RWND_CONTROL.
    net/tcp:  Take read-ahead throttling into account when calculating the TCP receive window size.
    net/tcp: tcp_get_recvwindow() now returns the receive window size directly (vs. indirectly via the device structure).
    net/tcp:  Remove CONFIG_NET_TCP_RWND_CONTROL.  TCP window algorithm is now trigged only by CONFIG_NET_TCP_READAHEAD.

net/tcp: Introduce tcp receive window control based on I/O buffer

NOTE: The algorithm is still experimental but useful for http streaming.
