If we have configured the DNS dispatcher to be only as a
responder but receive a query response, or if we are only
as a resolver but receive a query, then the dispatcher just
ignores the packet and returns -ENOENT.
Unfortunately we print an error message in this case
[00:10:18.818,000] <err> net_dns_dispatcher: DNS recv error (-2)
which is totally unnecessary and causes confusion so do not
print an error message in this case.

Coverity reported that a formula used to calculate the next expected
block in case the block size from the request differs our own block size
has a bug. The expression used to calculate the block size diff would
evaluate to an unsigned integer, giving (wrongly) enormous results in
case block size from the request is smaller than the Zephyr's default.
It turns out however, that this formula is no longer needed at all.
Since commit d3081e2f30, Zephyr's LwM2M
implementation will no longer negotiate the block size in case of write
operation, but simply comply with the block size included in the
request. This means that calculating the diff makes no longer sense and
can be safely removed - the next expected block number should be simply
increased by 1.

For each of the fdtable.h functions listed below, convert the
z_ prefixed semi-private functions to use the zvfs_ prefix.
ZVFS stands for Zephyr Virtual File System and
is intended to be a common library used by the C library,
POSIX API, Networking, Filesystem, and other areas.
There are already a few functions in fdtable.h that use the
zvfs_ prefix, so this change is mostly about unifying them in
a way that uses a suitable prefix ("namespace") so that it can
be considered a public API.
- z_alloc_fd
- z_fdtable_call_ioctl
- z_finalize_fd
- z_finalize_typed_fd
- z_free_fd
- z_get_fd_obj
- z_get_fd_obj_and_vtable

A few issues were identified with DNS_SD segment buffers, making it work
"by chance" (depending on memory layout):
- size check in dns_sd_query_extract() did not take NULL termination
into account, and in result could overflow provided buffer
- the proto_buf in send_sd_response() can either be used to parse
protocol or domain, depending on number of segments in the query.
It should therefore be large enough to hold either.
- Similarily, instance_buf should be able to hold
DNS_SD_INSTANCE_MAX_SIZE, not DNS_SD_SERVICE_MAX_SIZE.

During socket setup, if one of the setsockopt() calls failed, the

are leaked.

We should return the errno value in such case, as ret will always be -1
on failure, which might misleading, as it does not give any hint on what
failed.
Also bump the log level of the error message, so the failure is visible
w/o needing to enable debug logs. Such a failure is fatal for the DNS
subsystem, so error level is justified here.

The `dns_data` buffer, allocated by the DNS dispatcher was dereferenced
twice - once in registered DNS handler, second time in the dispatcher
itself.
Since the buffer was allocated by the dispatcher, and it's not really
guaranteed that the buffer will be freed in the registered handler (this
depends on the processing outcome, the function may return early w/o
freeing the net buf in case of errors), it makes most sense for the
dispatcher to keep ownership of the buffer. Hence, the registered
handlers will no longer release the buffer provided in any case, and the
dispatcher will free it on exit.
