Move some files back to the server "library".
Merge the 'console' lib with server, as it doesn't really make sense with
just one file and nobody exclusively linking to it.
The server "libary" is not really a library, its the place we put all
the files shared by hub-qt hub-cli and hub.
We no longer depend on these files from other places (mostly due to
moving to the new logging framework) and as such we can move the files
back.
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.
On low core-count machines the request to save could end up being
delayed since all threads are busy doing things like validating
transactions.
So when a really big block came in I ended up throttling while there
was no save method running in parallel at all.
This fixes this and also makes throtteling be a per-thread thing
instead of doing it inside the mutex.
Actually delete the asio io_service when we are done with it since that
will delete any left over tasks in the queue.
This makes deletion order more predictable.
