MAPL and ESMF usage in GCHP to preserve in MAPL3

[lizziel]

This issue is for tracking MAPL and ESMF usage in GCHP during development of MAPL3. I did a grep of all MAPL_ and ESMF_ calls within directory GCHP_GridComp. This is a parent gridcomp containing child gridcomps for GEOS-Chem (including HEMCO), advection, and a cinderalla interface between the two. Let me know if you need anything else.

Note that to make the files more useful I deleted results for DynCore and advection standalone.

@lizziel Thanks. I took a quick skim and at least did not see anything that gave me an "uh oh" moment.

A lot of the ESMF calls are for config files and attributes. Generally for MAPL3 we are heading towards hconfig and info as the preferred ESMF replacement for these. The former will generally be compatible with hconfig files, so might not require changes for simple cases. For the latter, we probably should get a stronger statement from ESMF about just how "deprecated" are attributes really.
