The tracker's HandleUpdate method is called by the ring update routines.
In addition, we add a dummy overlay for AWSVPC to make `weave (status|
report)` to produce reasonable reports which includes AWS hosts
connection state.
Merging a ring now indicates whether the ring has been updated. This
prevents excessive allocation retries, which in turn can result in
repeated space requests - i.e. if an allocation cannot proceed due to
lack of space - which in turn can result in excessive ring
fragmentation since many of the requests will result in the creation
of a new ring entries, due to the need to split ranges.
Fixes#2181.
This is mostly a matter of moving some files, changing package names,
changing some imports, and changing some type references.
We duplicate the odd constant & global var, and the intmac/macint
functions, since neither 'router' or 'mesh' nor, really,' common' are
a natural home for them.
tidy Address helper functions,
make ordering of members consistent in allocate and claim,
make linter happier,
remove some unused items, and
update some comments
when granting a range that spans a token and inserting a new token, the
free space on the last token that we are handing over has to change.
Add unit test for this too.
