multi: add custom error messages to channel acceptor
This commit adds an optional error message to the channel acceptor's
reponse to allow operators to inform (or insult) unsuccessful channel
initiators as to the reason for their rejection.

This field is added in addition to the existing accept field to maintain
backwards compatibity. If we were to deprecate accept and interpret a
non-nil error as rejecting the channel, then received a response with
accept=false and a nil error, the server cannot tell whether this is a
legacy rejection or new mesage type acceptance (due to nil error),
so we keep both fields.

multi: move channel acceptor logic out of rpcserver
This commit moves and partially refactors the channel acceptor logic
added in c2a6c86e into the channel acceptor package. This allows us to
use the same logic in our unit tests as the rpcserver, rather than
needing to replicate it in unit tests.

Two changes are made to the existing implementation:
- Rather than having the Accept function run a closure, the closure
  originally used in the rpcserver is moved directly into Accept
- The done channel used to signal client exit is moved into the acceptor
  because the rpc server does not need knowledge of this detail (in
  addition to other fields required for mocking the actual rpc).

chanacceptor: adding tests for the RPCAcceptor
This commit adds the TestRPCMultipleAcceptClients test which asserts
that the RPCAcceptor correctly handles multiple Accept callers.

chanacceptor: Adding Chained and RPC acceptors
This commit introduces the chanacceptor package which is used
to determine, by a set of heuristics, which open channel messages
to accept and reject. Currently, two acceptors are implemented
via the ChannelAcceptor interface: ChainedAcceptor and RPCAcceptor.
The RPCAcceptor allows the RPC client to respond to the open channel
request, and the ChainedAcceptor allows a conjunction of acceptors
to be used.
