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.

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.

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.

net/tcp: Be consistent with units of TIME_WAIT. Units were unspecified in tcp/Kconfig, but assumed to be in units of half seconds in tcp/timer.h. include/nuttx/netconfig does not indicate the units but is apparently assuming seconds. This commit unifies all delays to clearly specified units of seconds.

Squashed commit of the following:
...
net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled.
net/tcp: TCP socket should not have to be connected to configure KeepAlive.
net/: Add a separate configuration to enable/disable KEEPALIVE socket options.
net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options.
net/tcp: Fix a backward conditional
net/tcp: Add some more checks and debug output to TCP-protocol socket options.
net/tcp: Cosmetic changes to some alignment.
net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes.
