Also make sure that we do not calculate total packet length many

With this commit it is possible to add priority to sent or received
network packets. So user is able to send or receive higher priority
packets faster than lower level packets.
The traffic class support is activated by CONFIG_NET_TC_COUNT option.
The TC support uses work queues to separate the traffic. The
priority of the work queue thread specifies the ordering of the
network traffic. Each work queue thread handles traffic to one specific
work queue. Note that you should not enable traffic classes unless
you really need them by your application. Each TC thread needs
stack so this feature requires more memory.
It is possible to disable transmit traffic class support and keep the
receive traffic class support, or vice versa. If both RX and TX traffic
classes are enabled, then both will use the same number of queues
defined by CONFIG_NET_TC_COUNT option.

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.

Create infrastructure that allows ethernet device driver to tell

to IPv4, UDP or TCP checksums. The driver can enable/disable checksum
offloading separately for Tx and Rx network packets.
If the device (ethernet in this case) can calculate the network
packet checksum for IPv4, UDP or TCP, then do not calculate the
corresponding checksum by the stack itself.

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

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.
