node, p2p: move network config out of Server

This silences a go vet message about copying p2p.Server in package node.

eth: skip transaction handling during fast sync

cmd/geth: fix console history exclusion

Calls to 'personal' API should be excluded from console history because
they can be called with an account passphrase as argument. The check for
such calls was inverted and didn't work.

This fixes an issue where it's theoretical possible to cause a consensus
failure when hitting the lower end of the difficulty, though pratically
impossible it's worth a fix.

eth: fixed double close of channel. Fixes #2555

This fixes an issue where the following would lead to a panic due to a
channel being closed twice:

* Start mux
* Stop mux
* Sub to mux
* Unsub

This is fixed by setting the subscriptions status to closed resulting in
the Unsubscribe to ignore the request when called.

accounts/abi: fixed unpacking in to already sliced interfaces

Previously it was assumed that wheneven type `[]interface{}` was given
that the interface was empty. The abigen rightfully assumed that
interface slices which already have pre-allocated variable sets to be
assigned.

This PR fixes that by checking that the given `[]interface{}` is larger
than zero and assigns each value using the generic `set` function (this
function has also been moved to abi/reflect.go) and checks whether the
assignment was possible.

The generic assignment function `set` now also deals with pointers
(useful for interface slice mentioned above) by dereferencing the
pointer until it finds a setable type.
