BSD Sockets API: Non-blocking API

[zephyrbot]

Reported by Paul Sokolovsky:

"As an application developer, familiar with BSD Sockets API (part of POSIX), I would like to non-blocking/timeout functionality for sockets in Zephyr."

This is extension of GH-3662, following API calls are to be affected:

• connect()
• accept() (TBC)
• recv()
• send()

It should be possible to specify timeout/non-blocking status via means close to POSIX (setsockopt()/fcntl(), to be confirmed).

The code has now been merged, but it's not easy to test non-blocking sockets on their own, there should be poll()-like support, which is ZEP-2228, so further changes may need to be done as part of it.

The current sample implementation in samples/net/sockets/echo_async/ seems to be supported only for TCP and IPv4 and it is working fine in this. But I would like to know if we have any plans of implementing/expanding the code to further support of UDP and IPv6 too like in the sample code echo_server
Also the current sample is working fine for the first time,but failing to be connected and send and recv the packets after some trials onwards on TCP socket

It seems there was a problem with the application at my end.The sample application works fine for packet transfer in TCP.
