5925112ee6 net: sockets: Preserve user_data for any net_context send() or recv()
We use ctx->user_data to hold socket flags. As each call to
net_context_recv() and net_context_send() overwrites its previous
value, we explicitly must pass the current ctx value there.

Without this, non-blocking socket was turned into blocking after
e.g. switching from receiving to sending.

9e02f7b644 net: sockets: Fix mask application in sock_set_flag()
We pass normal 1-based mask, and mask invert it before logically
AND'ing with the value. This apparently a mix-up between how the
mask was intended to be passed initially and how it was in the end.
This issue actually didn't have an effect, because currently defined
flags have mutually exclusive lifetime (when "eof" flag is set,
"non-blocking" flag value is no longer import). Anyway, that's a
bug and needs fixing.

ebc81bdf8d net: http: Provide destination address in http replies
net_app_ctx maintains multiple net contexts(net_ctx). But when http
api's wants to reply or send some data, its always choose the first
net_context in the array, which is not correct always.

net_app_get_net_pkt_with_dst() api will select proper context
based on destination address. So with the help of new api in
net_app, http can select proper context and send packets. To
achieve this, desination address is provided in http_recv_cb_t
and http_connect_cb_t callbacks. Also chaged relevant API's to
provide destination address in http message preparation methods.

e9c0d001fa net: http: client: remove payload send_chunk logic
Logic for sending chunks of data is incompatible with adding
Content-Length: header.

Per https://tools.ietf.org/html/rfc7230#section-3.3.1:
"A sender MUST NOT send a Content-Length header field in any
message that contains a Transfer-Encoding header field."

Going a bit further in my mind: also don't send Transfer-Encoded
chunked data either when the Content-Length header is present.

In general, there will be problems if the http client library
makes payload changes without the user code knowing about it.

This patch removes the use of http_send_chunk() from the new
HTTP client code and instead sends the payload directly to
http_prepare_and_send()

This fixes an issue where every available buffer would be allocated
with repeating payload data because the for loop in http_request()
wasn't ending until we ran out of memory.

NOTE: This patch was previously applied but was lost when
commit d1675bf3e6 ("net: http: Remove the old legacy API")
moved code around.

fcb5e2b1ee net: http: honor CONFIG_HTTP_CLIENT_NETWORK_TIMEOUT setting
We should not use the user suppied timeout setting in
http_client_send_req() for the connection timeout.  In the
previous API the call to tcp_connect() used
CONFIG_HTTP_CLIENT_NETWORK_TIMEOUT as the timeout setting.

Let's do that here too.

This fixes -ETIMEDOUT error generation when using K_NO_WAIT
for http_client_send_req().
