Fold vacuum's 'int options' parameter into VacuumParams.

Browse Source 
Many places need both, so this allows a few functions to take one
fewer parameter.  More importantly, as soon as we add a VACUUM
option that takes a non-Boolean parameter, we need to replace
'int options' with a struct, and it seems better to think
of adding more fields to VacuumParams rather than passing around
both VacuumParams and a separate struct as well.

Patch by me, reviewed by Masahiko Sawada
