- use builderid as a foreign key instead of using buildername for the table buildrequests
 - addbuilset take a list of buildersID
 - check signatures for the BaseScheduler?'s addBuildsetForXxx methods
Add @defer.inlineCallbacks to br_consumer_cb and buildRequestAdded
I think this is needed since a12242da69e76f34cc45523c5a928b19e676d3ff. Dustin, do you confirm ?
Fix: master/buildbot/status/master.py:423: import 'builder' from line 25 shadowed by loop variable
use package_data to bundle various data files

* remove generation of MANIFEST.in (only helps for `sdist` command)
* override setuptools' build_py class to filter out directories

Supersedes GH-1215
Fixes ticket:2883
 - improve master/db/migrate/versions/037_buildrequests_builderid.py as dustin suggested
 - various minor fix
 - Done:
   - DB API changes reflected in the doc
   - DATA API changes reflected in the doc
   - DATA API for buildrequest's dropping /builders/i:buildername/buildrequests or not (code drops, path still in place)
   - DATA API changes need to be reflected in the FakeData API
   - trigger steps now gets {builderid:buidrequestid} back from the sched.trigger call
   - Try Schedulers's RemoteBuildSetStatus.getBuildRequest should return builder names but returns builder ids
 - todo:
   - SchedulerMixin._addBuildsetReturnValue returns buildernames, but should return builderids
   - BuilderStatus.getPendingBuildRequestStatuses calls db.getBuildRequests (... buildername=...". It's Ok to just assert 0 in this method.
     The whole class will go away soon. Just don't leave it subtly broken

re-raise the original exception when cleaning the database

This ensures we get a full traceback from the point where that exception
was raised.
Fix the type of the 'masterid' case statement

It seems that newish versions of pg8000 complain (probably correctly)
that a case statement is of text type, but the masterid column should be
an integer.  This adds an explicit cast, which works fine across all
three database engines.
