functionObjects/setTimeStep: Compatibility with 'adjustableRunTime'

Browse Source 
setTimeStep is now compatible with a 'writeControl adjustableRunTime;'
setting in the systemControlDict. If 'adjustableRunTime' is selected
then the time-step values set by this function object will not be
exactly as specified, but write intervals will be matched exactly.

All function object time adjustment is now done during the execute
methods, so the specific setTimeStep hooks have been removed.

Foam::functionObjects::setTimeStepFunctionObject
Description
Updates the writeInterval as a Function1 of time.
Updates the time step as a Function1 of time.
Can only be used with solvers with adjustTimeStep control
(e.g. pimpleFoam). Makes no attempt to cooperate with other timeStep
'controllers' (maxCo, other functionObjects). Supports 'enabled' flag but
none of the other ones 'startTime', 'endTime', 'writeControl' etc.
Makes no attempt to cooperate with other timeStep controllers (i.e., solver
courant number control or other functionObjects). In general any value set
here will be overwritten by solver time-step adjustment if enabled, so for
this to work 'adjustTime' should be switched off. This is compatible with
'adjustableWriteTime', in which case the time-step values set will not be
exactly as specified, but write intervals will be matched exactly.
This function supports the 'enabled' flag but none of the other run
controls; 'startTime', 'endTime', 'writeControl', etc...
