collect: making some protocol parameters configurable by COLLECT_CONF_ style defines
...
TTL (which has a rather low default of 15), MAC level retransmissions,
overall number of retransmissions, and the header bits dedicated to these
were all fixed in the collect.h and collect.c, without a simple way to
override them.
Extracted these as COLLECT_CONF_ parameters, keeping defaults as they were
before.

Avoid using memcpy on unaligned uint16_t variables, because certain compilers will optimize this code to a direct copy instruction that will result in unaligned memory access. Thanks to Angelo Compagnucci for reporting this problem.

Minor bugfixes pertaining to queue handling: if a packet was explicitly dropped, the packet would later be acknowledged despite it never being received; added a limit on how many queue entries that can be used for packets that are being forwarded, to allow for originated packets even if the forwarding queue is filled.

Rewrite of the congestion logic. A node now report it being congested
...
when half the transmission queue is full. When a neighbor is heard to
be congested, the rtmetric of that node is inflated to avoid sending
more traffic in its direction.
Fixed problems with beacon intervals: intervals are now not reduced
when a path gets significantly worse, only when they get better.

A number of changes to the collect code:
...
* Added an optional "keep alive" mechanism whereby an idle network is
periodically probed by dummy packets to maintain a recent quality
metric when there is no traffic.
* Bugfix in when new routing metrics should be advertised
* Rewrote the ACK logic so that a queuebuf is not allocated for each
ack, only for those acks generated by the sink node.
* Updated the wrap-around logic for sequence numbers: when a sequence
number wraps, it won't go back to 0. Instead, it wraps to 128. This
allows us to understand when a node has rebooted: when its seqno is <
128, it has recently rebooted.

Significant improvements to the Collect protocol:
...
* Loop detection and untangling. Now uses in-band loop detection that
works.
* Link quality estimation. Now starts with a conservative /
pessimistic estimate for new links.
* Retransmissions. MAC layer and network layer retransmissions are now
decoupled.
* Loss handling. Deals better with losses now.
* Concurrent applications. Each connection now maintains its own
neighbor table with separated cost to sink estimates for each
connection.

* Added configurable default number of transmissions for CSMA to use when not specified using packetbuf attributes (CSMA_CONF_MAX_MAC_TRANSMISSIONS).

* Renamed packetbuf attribute PACKETBUF_ATTR_MAX_MAC_REXMIT to PACKETBUF_ATTR_MAX_MAC_TRANSMISSIONS where value 0 (attribute not set) means that default number of transmissions should be used.
