Replace foamList utility with -list.* options

Provides better context for the available boundary conditions, fvOptions,
functionObjects etc. and thus returns only those available to and compatible
with the particular application.

e.g.

pimpleFoam -help

Usage: pimpleFoam [OPTIONS]
options:
  -case <dir>       specify alternate case directory, default is the cwd
  -listFunctionObjects
                    List functionObjects
  -listFvOptions    List fvOptions
  -listRegisteredSwitches
                    List switches registered for run-time modification
  -listScalarBCs    List scalar field boundary conditions (fvPatchField<scalar>)
  -listSwitches     List switches declared in libraries but not set in
                    etc/controlDict
  -listTurbulenceModels
                    List turbulenceModels
  -listUnsetSwitches
                    List switches declared in libraries but not set in
                    etc/controlDict
  -listVectorBCs    List vector field boundary conditions (fvPatchField<vector>)
  -noFunctionObjects
                    do not execute functionObjects
  -parallel         run in parallel
  -postProcess      Execute functionObjects only
  -roots <(dir1 .. dirN)>
                    slave root directories for distributed running
  -srcDoc           display source code in browser
  -doc              display application documentation in browser
  -help             print the usage

Further work will be needed to support the -listTurbulenceModels option in
multiphase solvers.
