ee509ff4f3 Re-Implement the nc_get/put_vars operations for netcdf-4 using the 
corresponding HDF5 operations.

re: github issue https://github.com/Unidata/netcdf-c/issues/908
also in reference to https://github.com/pydata/xarray/issues/2004

The netcdf-c library has implemented the nc_get_vars and nc_put_vars
operations as element at a time. This has resulted in very slow
operation.

This pr attempts to improve the situation for netcdf-4/hdf5 files
by using the slab operations provided by the hdf5 library. The new
implementation passes the get/put vars stride information down to
the hdf5 slab operations.

The result appears to improve performance significantly. Some simple
tests on large 2-D arrays shows speedups in excess of 150.

Misc. other changes:
1. fix bug in ncgen/semantics.c; using a list's allocated length
   instead of actual length.
2. Added a temporary hook in the netcdf library plus a performance
   test case (tst_varsperf.c) to estimate the speedup. After users
   have had some experience with this, I will remove it, probably
   after the 4.7 release.
