MOSAIC implementation checkpoint 2

Commit shows the modifications need to MOSAIC:

MOSAIC/BaseCode/main/module_mosaic_support.f90
   - Add GEOS-Chem-compatible warning and error messages
MOSAIC/BaseCode/datamodules/module_mosaic_main.f90
   - Add:
!$OMP THREADPRIVATE( cnn                                  )
!$OMP THREADPRIVATE( cair_mlc, cair_molm3, h2o, o2        )
!$OMP THREADPRIVATE( h2, speed_molec, te, pr_atm, RH      )
!$OMP THREADPRIVATE( pblh, cair_mlc_old, cair_molm3_old   )
!$OMP THREADPRIVATE( te_old, pr_atm_old, RH_old, pblh_old )
     at the end

The subroutines init_aerosol, water_vapor, setaircomposition and
init_data_modules also need to be copied into the relevant
positions in mosaic_mod so that GEOS-Chem can see them (if
they have changed).

Although it does compile, the code does not yet run - need to get
input options sorted out, tracers to be recognized as aerosol vs gas,
updates to chemistry etc..

MOSAIC implementation checkpoint 3

This commit just tracks movement of files from MOSAIC/ to
MOSAIC/BaseCode/ - the code now compiles, although it does not run
(see last commit).
