Eelco Dolstra 008d610467 getQueuedBuilds(): Don't catch errors while loading a build from the queue 
Otherwise we never recover from reset daemon connections, e.g.

  hydra-queue-runner[16106]: while loading build 599369: cannot start daemon worker: reading from file: Connection reset by peer
  hydra-queue-runner[16106]: while loading build 599236: writing to file: Broken pipe
  ...

The error is now handled queueMonitor(), causing the next call to
queueMonitorLoop() to create a new connection.

Otherwise, you'd have to restart the queue runner to add or remove
machines.

Eelco Dolstra 62219adaf3 Send queue runner stats to statsd 
This is currently done by a separate program that periodically
calls "hydra-queue-runner --status". Eventually, I'll do this
in the queue runner directly.

Fixes #220.

Eelco Dolstra 4db7c51b5c Rate-limit the number of threads copying closures at the same time 
Having a hundred threads doing I/O at the same time is bad on magnetic
disks because of the excessive disk seeks. So allow only 4 threads to
copy closures in parallel.

Eelco Dolstra a317d24b29 hydra-queue-runner: Send build notifications 
Since our notification plugins are written in Perl, sending
notification from C++ requires a small Perl helper named
‘hydra-notify’.

Eelco Dolstra d744362e4a hydra-queue-runner: Fix segfault sorting machines by load 
While sorting machines by load, the load of a machine
(machine->currentJobs) can be changed by other threads. If that
happens, the comparator is no longer a proper ordering, in which case
std::sort() can segfault. So we now make a copy of currentJobs before
sorting.

Eelco Dolstra 9cdbff2fdf Handle concurrent finishing of the same build 
There is a slight possibility that the queue monitor and a builder
thread simultaneously decide to mark a build as finished. That's fine,
as long as we ensure the DB update is idempotent (as ensured by doing
"update Builds set finished = 1 ... where finished = 0").
