Remove NET_UDP_HDR() macro as we cannot safely access UDP header
via it if the network packet header spans over multiple net_buf
fragments.
Fixed also the UDP unit tests so that they pass correctly.

The IPv6 HBH option PAD1 ext header was not parsed properly
as the code read one extra byte from the ext header. The
PAD1 length is only 1 byte.

Add utility function that helps to figure out if the
protocol headers can be directly accessed when they fit one
net_buf fragment, or if they need to accessed using various
net_pkt helpers that know about reading data from two
different net_buf's.

Instead of directly setting pointer to where to start to calculate
the various IP related checksums, use the net_frag_skip() to first
find out what is the fragment where the calculation should start.
This needs to be like this so that if the IP header + possible
extension are so long that they do not fit the first fragment,
we need to be prepared to look into second fragment.

The following error and warning is received when connecting
to certain central devices:
[bt] [ERR] hci_num_completed_packets: packets count mismatch
[bt] [WRN] bt_att_recv: Ignoring unexpected request
This could happen if Tx-ed packet is not added to pending
list before a num of completed packets event and/or new Rx
packet is received.
This is fixed by reducing the Rx thread priorities in the
Host and the Controller.

net_context_unref() is protocol agnostic, after being un-referenced,
the same context might end up being used then for UDP,
if context->tcp is not reset to NULL, calling net_context_unref()
after this UDP usage will again try to release this TCP pointer
which might lead to random error.

The chip seems to require a wait time before reading packet
data after the RX sequence done interrupt, as imidiate reading
of it will indicate a packet size of zero and cause the RX
sequence done to be continually retriggered.
In addition, the extra clearing of the interrupt flags can be
removed, as this is already done at the beginning of the isr.

Add an array of configurable size that holds TCP backlog entries.
The array is shared between all incoming TCP connections in order
to make it possible to get away with less memory consumed than
with a connection based approach.
The backlog entries are created when a SYN is received for a
listening TCP socket and removed once the corresponding ACK is
seen. With an incoming RST the corresponding backlog entry is
cleared, if any.
The size of the global backlog array is defined with the
CONFIG_NET_TCP_BACKLOG_SIZE Kconfig variable.
