If getaddrinfo() was called with AI_PASSIVE flag in hints,
returned address defaulted to SOCK_STREAM and IPPROTO_TCP.
Fixed so that SOCK_DGRAM leads to correct address type
that can be fed to bind() directly.
Same hard coding was visible when numerical IPv4 address string
was converted to binary. That is also fixed to respect hints now.
Also, added functionality to get IPv6 address, when hints contained
AF_INET6.

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.
Almost all of this is straightforward swapping of one alloc/free call
for another. In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.
Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

LwM2M engine by default sends piggybacked responses for requests after
all callbacks are executed. This approach however isn't good enough if
the application callback executes some lenghty operations (for instance
during FW update). Delaying the ACK may result in unnecessary
retransmissions.
This commits adds an API function which allows to send an early empty
ACK from the application callback. This prevents further retransmissions
from the server side. After all callbacks are executed, the LwM2M engine
will send the response as a separate CON message.

Rework the bootstrap DELETE operation, to support deletion of multiple
resources.
Current implementation had several oversimplifications, making it not
spec-compliant:
* DELETE `/` removed only Security object instances (!= 0)
* DELETE `/x` was handled as DELETE `/x/0`, therefore not removing all
of the object instances.
Since the above is only supported during bootstrap and not regular
Device management, this functionality was implemented in the
`bootstrap_delete` function, which now will be called for all DELETE
operations initiated during bootstrap. The regular LwM2M DELETE handler
will only be called during regular Device management, as it has more
strict limitations on what can be deleted.
Additionally, handle empty URI Path option as `/`, therefore indicating
deletion of all resources.

Set the RX/TX thread priorities so that if cooperative priorities
are used, then lowest priority thread will have priority -1 which
is the lowest cooperative priority. The higest net thread priority
will depend on number of traffic classes but with max value 8,
the highest priority will be -8.
If preemptive priorities are used, then highest priority thread
will have priority 0, which is the highest preemptive priority.
In this case, the lowest thread priority will be 7 if there are
8 traffic classes.
The motivation for this change is that for cooperative priorities
we want to let other cooperative priority threads to run before
networking. But if preemptive priorities are used, we want
networking threads to run reasonably often compared to other
preemptive priority threads.

Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).
Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.
For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.
