The original commit 8ebaf29927 ("net: http: dont timeout
on HTTP requests w/o body") was intended to handle a case
where an HTTP response had been retrieved from the server but
the HTTP parser couldn't meet the criteria for calling
"on_message_complete". For example, a POST to a REST API
where the server doesn't return anything but an HTTP
status code.
It was a really bad idea to check a semaphore count. There
is a lot of kernel logic built into semaphores and how the
count is adjusted. The assumption that the value is 0
after the k_sem_give() is incorrect. It's STILL 0 if
something is pending with a k_sem_take(). By the time
k_sem_give() is done executing the other thread has now
been kicked and the count is back to 0.
This caused the original check to always pass and in turn
breakage was noticed in the http_client sample.
Let's do this the right way by setting a flag when
on_message_complete is called and if that flag is not set
by the time we reach recv_cb, let's give back the semaphore
to avoid a timeout.

The HTTP header field pointers are saved for each HTTP request.
But the counter that saves the pointers was never reset to initial
value when the connection was dropped. This meant that the header
field values were only proper for first HTTP request.

Zeroing-out all bytes from a connection structure when it's

If either a remote or a local address were supplied to the
net_conn_register() function, the IP stack would proceed to copy
sizeof(struct sockaddr) bytes from the respective remote_addr
or local_addr pointers, regardless of the actual size of the storage
these pointers point to.
Use the proper size depending on the socket address family.

[michael.scott@linaro.org: re-worked patch post addition of CREATE
operation.]
Signed-off-by: Michael Scott <michael.scott@linaro.org>
Prior to this patch, a CREATE operation was handled as a WRITE operation
after the object instance was created. This becomes problematic when
handling of optional resources differs between these 2 operations.
Let's introduce an actual CREATE operation and use it later to create
these differences.

We are returning EINVAL from content format write ops when an object
field definition is not found (an optional field which is not
implemented). Instead, return ENOENT which lets the LwM2M engine
know to send ZOAP_RESPONSE_CODE_NOT_FOUND to the LwM2M server at the
end of handle_request().
NOTE: This behavior is not correct when we call the writer right after
a CREATE operation where the data is assigned to resources for the
first time. This case will be handled in a follow-up patch once we're
able to distinguish between a WRITE and a CREATE in the write op
handler.

A TCP FIN message is passed on to user apps as a tcp_received_callback
with a NULL pkt parameter. This means the connection is closing and
the app should do whatever cleanup it needs as there will be no further
callbacks for the current TCP connection.
Currently, if a HTTP client request doesn't receive a "body" which
the HTTP parser can use to trigger on_message_complete, then the request
will end up timing out and most apps will think an error has occurred.
Instead, let's handle the TCP FIN message and return the waiting
semaphore, leaving the app to deal with whatever has been set in the
current HTTP context response data (IE: http_status).
This fixes using HTTP client to send POST data to servers which
only respond with HTTP_OK status and no body.
