95c4294560 Allow cancelling builds marked as busy 
Note that if there are active build *steps*, this won't cancel them.

35b7c4f82b Allow only 1 thread to send a closure to a given machine at the same time 
This prevents a race where multiple threads see that machine X is
missing path P, and start sending it concurrently. Nix handles this
correctly, but it's still wasteful (especially for the case where P ==
GHC).

A more refined scheme would be to have per machine, per path locks.

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.

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.

7e6135a8c6 Don't repeat links to build step logs

show log links for the last one.

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.

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.

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.

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.

a317d24b29 hydra-queue-runner: Send build notifications

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.
