Options parsing helpers functions unable to handle the malformed
packets and dropping it. Improved parsing functionality to handle
malformed packets. Also payload marker is not mandatory in CoAP
packets when there is no payload. Exit gracefully when CoAP
packet contains only options.

The implementation of the Network Message Cache has so far been
suboptimal, since it has treated the same packet with different TTL
values as different packets. Since one of the purposes of this cache
is to prevent unnecessary relaying, it's important that we don't let
the TTL value influence the "hash" that's used for matching messages.
This patch changes the hash to consist of most of the IV Index (three
least significant bytes of it), the sequence number and the source
address, which should give fairly optimal matching behavior.

If IEEE 802.15.4 reassembly function ieee802154_reassemble() returns
anything other than NET_CONTINUE, then drop that packet. Earlier
it only dropped the packet if NET_DROP was returned but the reassembly
might also return NET_OK. In that case the pkt is freed already and
pkt->frags pointer is NULL. This caused NULL pointer access in L2 when
packet was received.

Previously net_pkt.h, defined macros NET_PKT_TX_SLAB_DEFINE,
NET_PKT_DATA_POOL_DEFINE, but advertised them as intended for
"user specified data". However, net_pkt.c effectively used the
same parameters for slabs/pools, but this wasn't obvious due
to extra config param redirection. So, make following changes:
1. Rename NET_PKT_TX_SLAB_DEFINE() to NET_PKT_SLAB_DEFINE()
as nothing in its definition is TX-specific.
2. Remove extra indirection for config params, and use
NET_PKT_SLAB_DEFINE and NET_PKT_DATA_POOL_DEFINE to define
system pools.
3. Update docstrings for NET_PKT_SLAB_DEFINE and
NET_PKT_DATA_POOL_DEFINE.
Overall, this change removes vail of magic in the definition of
system pkt slabs/pools, making obvious the fact that any packet
slabs/pools - whether default system or additional, custom - are
defined in exactly the same manner (and thus work in the same manner
too).
