Dennis Heimbigner 6934aa2e8b Thread safety: step 1: cleanup
re: https://github.com/Unidata/netcdf-c/issues/1373 (partial)

* Mark some global constants be const to indicate to make them easier to track.
* Hide direct access to the ncrc_globalstate behind a function call.
* Convert dispatch tables to constants (except the user defined ones)
  This has some consequences in terms of function arguments needing to be marked
  as const also.
* Remove some no longer needed global fields
* Aggregate all the globals in nclog.c
* Uniformly replace nc_sizevector{0,1} with NC_coord_{zero,one}
* Uniformly replace nc_ptrdffvector1 with NC_stride_one
* Remove some obsolete code
