c89a06dbc1 net: config: Introduce a dedicated header for the library
Split out definition of net_app_init() and its parameter flags from
net_app.h header to new net_config.h header. As we do this, rename
the function to net_config_init() and flags to NET_CONFIG_NEED_*.
This is a second step in splitting out network configuration API
out of net_app API, started in the c60df1311 commit.

5cc4ef78d3 net: app: TLS client handling issue when server closes connection
The client TLS code did not handle server issued close properly.
Now the connection is terminated properly and TLS thread is left up to
wait more requests from the user.

This commits adds new boolean field to net_app context. Because there
are already multiple boolean flags there, convert them all to bitfields
to save space.

9090bdfc10 net: app: Close TLS connection properly
We should not close the TLS connection immediately if the TLS
data is not yet sent. So if user calls net_app_close() and we
still have data pending, then send the TLS data and only after
that close the connection.

c5c104f91e kernel: fix k_thread_stack_t definition
Currently this is defined as a k_thread_stack_t pointer.
However this isn't correct, stacks are defined as arrays. Extern
references to k_thread_stack_t doesn't work properly as the compiler
treats it as a pointer to the stack array and not the array itself.

Declaring as an unsized array of k_thread_stack_t doesn't work
well either. The least amount of confusion is to leave out the
pointer/array status completely, use pointers for function prototypes,
and define K_THREAD_STACK_EXTERN() to properly create an extern
reference.

The definitions for all functions and struct that use
k_thread_stack_t need to be updated, but code that uses them should
be unchanged.

4fea5b18ab net: app: Add IP header to packets received by TLS/DTLS tunnel
The IP header was stripped by _net_app_ssl_mux() when it received
IP packet. This is fine but if the application expects the get
the IP header, then there is a problem. Fix this by saving IP
header to ssl_context and then putting it back in front of the
packet when the data is passed to application.
Note that this IP header is not used by net_app when the packet
is sent because TLS/DTLS creates a tunnel for transferring packets
and user can only sent packets via this tunnel.

507852a4ad kernel: introduce opaque data type for stacks
Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.

This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.

We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.

To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.

This should catch a bunch of programming mistakes at build time:

- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
  passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
  which is not actually the memory desired and may trigger a CPU
  exception

539b0c46ff net: doc: Add missing defgroups to network header files
Some of the networking header files in include/net/ directory were
missing @defgroup doxygen directives.

There was also duplicate @defgroup directives which are now changed
to @addtogroup directives.

Added also missing API links to doc/api/networking.rst file.

Added exceptions to .known-issues/doc/networking.conf file so that
doxygen does not complain.

a1be6a8ba9 net: app: Create support for network application API
The network application API is a higher level API for creating
client and server type applications. Instead of applications
dealing with low level details, the network application API
provides services that most of the applications can use directly.

This commit removes the internal net_sample_*() API and converts
the existing users of it to use the new net_app API.
