aa9a24aa25 net: lwm2m: remove LWM2M_OP_NONE flag and renumber the rest
Remove unused OP flag LWM2M_OP_NONE and renumber the existing flags
so that the operations used in object permissions land in the lowest
bits, and extended operations come later.

We may eventually add more permission / data flags, so let's try and
keep them inside a 1 byte boundary (flags with bits 0 to 7).

NOTE: LWM2M_OP_DELETE is currently not checked as a permission but
it may be in the future so it is in the lower bits.

5da0d2928f net: dns: Fix end-of-results callback on error
Callers of dns_get_addr_info() depends on receiving an end-of-results
callback (where 'info' is NULL) when finished. Do this on failure in
cb_recv() instead of pointing to an empty object.

This fix will avoid a deadlock situation in getaddrinfo().

A reply code other than "no error" in the DNS response is a typical
case when the lookup failed and this occurs.

Moved "struct dns_addrinfo info" variable from cb_recv() to dns_read()
because it was now unused in cb_recv().

Adding tests for this requires network access and a DNS server,
or a mechanism for generating a DNS response with a reply code.

ca8b00a3cc net: if: Make interface IP configuration more flexible
Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.

This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).

Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.

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")
