Move some globals and all stuff pulling in crypto to the
server/serverutil.cpp file
Remove dead code.
Move several items that were used in only one place to the respective
files using them.
Move the class WaitUntilFinishedHelper into its own file.
Made sure no header includes utils.h
remove a handfull of files including utils.h for nothing.
The main goal of this is to make sure that network services
implementations don't reuse one bufferpool for all their remotes as that
can cause threading issues.
One bufferpool per remote is now made easy.
In extreme cases we might end up going over the bounds of the internal
buffers, as such myConnection.send() may now throw.
I also cleaned up the ping design and made it a bit more strict.
Last I increased the amount of incoming data I can receive in one go,
this will make throughput higher.
