Every module in layers/ is imported automatically, so two modules
registering the same name silently replaced one with the other, in an
order decided by pkgutil. Registration now raises, so the mistake is
found when the configuration is loaded.

- Reset the link after max_retries even when it is 255, where the retry
counter used to wrap
- Require a reliability timeout of at least 50 ms
- Drop received frames larger than the layer's max_packet_size
- Fail setup, instead of aborting, when the send queue cannot be
allocated or max_packet_size leaves no room
- Test the ack delay timer and a refused REJ

Layers stack on a link and are configured on its packet_interface entry.
Each layer type registers itself with its kind, so a new type needs only
a new module. The first is a reliability layer in the style of HDLC
asynchronous balanced mode, with go-back-N retransmission.

Each packet is one UDP datagram, using the settings of the udp component.
The udp component now reports whether a packet was sent, and an ENOMEM
refusal from lwIP is logged at verbose level as the packet can be sent
again.

A packet interface moves packets over a channel, with a uart link and a
packet_transport platform that uses any packet interface. Later layers
stack on the same base class.
