The sample oversimplified the observe mechanism a bit - instead of
making use of CoAP APIs to verify the packets received (if they are
actually notifications for the observe) it blindly assumed that any
received packet was a notification. This could be misleading for
potential users of the CoAP library, as the sample had little use as
a reference for the Observer functionality.
Fix this by making use of `coap_reply` structure and a corresponding
`coap_response_received()` function.
Additionally, make the observe cancellation compliant with the CoAP
specification - it should be either an empty Reset message, or a GET
request with Observe option set to 1. The sample used invalid
construct of a Reset message with Observe option. For the purpose of
the sample, use the latter option.

The root CA used so far (GlobalSign R2) is about to expire soon
(December 2021) and Google have switched to a new certificate, signed by
GlobalSign R1 (valid until 2028). Therefore we need to replace the
root CA used by the sample to the new one, in order to establish secure
connection to with google.com.
Additionally, the new certificate chain sent by Google is larger again,
so it's needed to increase mbed TLS max content length parameter in
order to process it correctly. This also implies an increase in heap
usage, so increase the heap size as well.

Adding NET_DRIVERS menuconfig so that network drivers are grouped
together in its own menu entry under drivers, similar to most other
drivers.
This further has the advantages that `CONFIG_NET_DRIVERS` can be used
for testing to determine if network drivers has been selected.
This changed revealed a dependency loop where both `select` (for SLIP)
and `depends` (for PPP) which both depends on NET_DRIVERS` where in use
in the dependency tree for Qemu networking, especially NET_SLIP_TAP.
This is handled by defaulting `NET_DRIVERS` to `y` when building for a
Qemu target.
`SLIP` had a dependency to `!QEMU_TARGET || NET_QEMU_SLIP`. This is
changed so that SLIP prompt depends on `!QEMU_TARGET` which provides
full user control in hardware but makes the symbol promptless on Qemu
targets.

The Google server that the sample connects to sends a larger certificate
since recently. As the overall size of the message conveying the
ceritificate is ~4700 bytes now, current mbedTLS configuration did not
allow to reassemble the message and thus caused failure during the
handshake.
Fix this by increasing MBEDTLS_SSL_MAX_CONTENT_LEN parameter (with some
extra space for any future changes).

The conn_raw_input() in connection.c will clone the incoming
packet so that it is possible to receive socket data in
multiple packet sockets. This is all fine except that if the
socket is never calling recv(), then the cloned net_pkt is never
processed and we will have a memory leak.
What this all means in practice, is that we should call recv()
for every packet socket in order to flush the socket for any
incoming data even if the socket is just sending data.

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

socket_can_generic.h makes some assumptions that are not always valid
for various drivers with regards to numbering. To clean this up we
add defines for SOCKET_CAN_NAME_0 and SOCKET_CAN_NAME_2 in addition to
SOCKET_CAN_NAME_1.
We also move struct socket_can_context into the drivers themselves
since they know best how many CAN interfaces are getting supported and
what naming/number convention they'd have.
Additionally, this also exposes a few other build issues with the
can_mcux_flexcan driver that get fixed.
Finally, we remove the platform_allow from samples/net/sockets/can
since it is no longer needed.
