Revert merging 'introduce-adapter of git://github.com/MichaelMayorov/buildbot".

This code isn't at the point where somebody could add a seperate protocol
without any core changes, yet.

This reverts commits 9f313d732025406e2cdfdf159d06d1441ed756d7,

Filter bulider's slavenames when reconfiguring

Fixes #2507.  Note that a build which has its builder/slave pair removed
whlie it is executing will still hang indefinitely, but that's a much
larger problem.
fix pyflakes
replaced depricated 'disable-msg' pylint pragma with 'disable'
locally disable pylint warnings triggered by interface definitions
unit tests: make _makeSUCTest() a local function

The TestGetUnversionedFiles._makeSUCTest() looks like a method but is

Fix pyflakes warnings on post_build_request.py
Update post_build_request to match change_hook

200 OK response code. Instead it returns a 202 Accepted code with
no data. This commit updates post_build_request.py to match this
behaviour.
