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.

3c7ffcc6d1 Fix https://github.com/Unidata/netcdf-c/issues/963 
Fix https://github.com/Unidata/netcdf-c/issues/962

1. remove the --disable-diskless option since it is no
   longer needed. Similarly for CMakeLists.txt.
2. Fixed nc4files.c where BAIL and return were mixed
   leading to situation where cleanup code was not
   being invoked. This probably occurs elsewhere,
   but I did not find any specifically.

There is an error in handling the nc_create_memio function
as noted in the above esupport thread.
This attempts to fix it.
