Adam Harrison bceabe32a2 Try all pending allocations
We can have outstanding allocations for different ranges owned by
different peers, so we should not short circuit after the first space
request.

Matthias Radestock 3cd199e852 make GossipData immutable
The same piece of GossipData can be shared and subject to different
Merge operations. We either need to copy the data when we share it, or
create copies on modification, i.e. copy-on-write.

We choose the latter, since it is more efficient and there is just one
mutating operation.

Fixes #1697.

Matthias Radestock dc9f8762ca move generic communication substrate into its own 'mesh' package
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.

Matthias Radestock 8bd77c0d47 refactor: get rid of router/utils.go

Matthias Radestock 751ccd02f6 don't stall in ipam on early container death
When a container died before we got into the allocation code (inside
the allocator run loop) we would not cancel the allocation since the
container death event will have been processed by the allocator before
it had any knowledge of the container.

The fix is to move the container-aliveness check inside the allocation
code. That way we still detect the death even if the event has already
flown past.

We only need to perform the check once, since any subsequent death
will result in an event that is processed by the allocator when it has
recorded the container in its state.

Fixes #1459.

Matthias Radestock 5a45471c68 more readable errors on ring.Merge
There are three significant changes here:

- rewrite ring.ErrDifferentSeeds errors
- remove the pre-checking of ranges and instead rewrite
  ring.ErrDifferentRange errors
- don't pruneNicknames() and signal ringUpdated() when there was an
  error

We don't rewrite other errors since our current belief is that only
ErrDifferentSeeds and ErrDifferentRange can arise from user error.

Michael Bridgen c88361473c Remove misleading comment and lowercase deniedBy
* the comment "don't make the caller wait" applies to both branches
   of that if clause, and having it on one branch implies the other
   does make the caller wait
 * there's no reason for DeniedBy to start with a capital: it's a
   method on a private struct and it's not part of an interface.
