Title: Get rid of grey_timeout and 'white' clients

These are noops: clients that retry before grey_timeout is exceeded and
clients that retry after grey_timeout is exceeded all pass greylisting until
expired by white_timeout.

This also adds tests for greylist() that were responsible for discovering this potential simplification.
