netcdf-c/h5_test/tst_h_dimscales4.c
Dennis Heimbigner 7e27052f87 - Implemented diskless files for both netcdf classic and extended. 
The in-memory files can be made persistent if nc_create is called with
  NC_DISKLESS|NC_WRITE flags set. Initial test case also included.
- Modified ncio mechanism to support
  multiple ncio packages; this is so we
  can have posixio and memio operating
  at the same time.
- cleanup up a bunch of lint issues (unused variables, etc).
