168ef61a63 Add missing locks and fix debug output, and try to flush queues

isUp is set to false.

A premature waitgroup .Done resulted in reading from closed channel.
This caused a nil-pointer deref & crash.

Added additional debugging when closing routines.

64-bit varibles that are accessed using the Go atomic functions must be
8-byte aligned on 32-bit platforms. Otherwise there are crashes.

bffe99aead Don't use modules 
Feel free to revert this if you have a strong feeling about it. But so
far as I can see, it adds a lot of complexity for basically no upsides.

029410b118 Rework of entire locking system 
Locking on the Device instance is now much more fined-grained,
seperating out the fields into "resources" st. most common interactions
only require a small number.
