Eelco Dolstra f52ca0c588 Add a redirect to the latest view result for which the underlying evaluation has finished completely 
This will be useful for the Nixpkgs channel mirror script:

  http://hydra.nixos.org/view/nixpkgs/unstable/latest-finished/channel

is the channel containing the latest, consistent, tested set of builds.

Eelco Dolstra 179b012a8e Open the DB using Hydra::Model::DB->new 
This gets rid of the openHydraDB function and ensures that we
open the database in a consistent way.

Also drop the PostgreSQL sequence hacks.  They don't seem to be
necessary anymore.

Eelco Dolstra bc82a82593 Fix a race condition in hydra-update-gc-roots 
Since it read the actual roots after determining the set of desired
roots, there was a possibility that it would delete roots added by
hydra-evaluator or hydra-build while hydra-update-gc-roots was
running.  This could cause a derivation to be garbage-collected before
the build was performed, for instance.  Now the actual roots are read
first, so any root added after that time is not deleted.

Eelco Dolstra 29d5a02b94 Speed up hydra-update-gc-roots 
The hydra-update-gc-roots script is taking around 95 minutes on our
Hydra instance (though a lot of that is I/O wait).  This patch
significantly reduces the number of database queries.  In particular,
the N most recent successful builds for each job in a jobset are now
determined in a single query.  Also, it removes the calls to
readlink().

Eelco Dolstra 25334715f8 Merge the BuildSchedulingInfo table into the Builds table 
This simplifies the code and improves performance since it reduces
the number of joins.

Eelco Dolstra 82d17a2d0b Rename hydra_*.pl to hydra-* 
The underscores are ugly and the .pl extension is an implementation
detail that shouldn't be visible to the outside.

Also, get rid of the *.in files.  It's not really necessary to
generate them.  And I was always modifying the wrong file.
