Eelco Dolstra dffb629b8a Unify Hydra's NixOS module with the one used for hydra.nixos.org 
In particular, the queue runner and web server now run under different
UIDs.

Eelco Dolstra 3e0f5f664a GitInput plugin: Don't clone during getCommits 
This doesn't work if hydra-queue-runner has no write access to the scm
directory, and in any case races with the evaluator.

Eelco Dolstra 7e6135a8c6 Don't repeat links to build step logs 
Hydra only stores the last log for a particular derivation, so only
show log links for the last one.

Eelco Dolstra 2ece42b2b9 Support preferLocalBuild 
Derivations with "preferLocalBuild = true" can now be executed on
specific machines (typically localhost) by setting the mandary system
features field to include "local". For example:

  localhost x86_64-linux,i686-linux - 10 100 - local

says that "localhost" can *only* do builds with "preferLocalBuild =
true". The speed factor of 100 will make the machine almost always win
over other machines.

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.

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

‘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").
