This PR adds a benchmark/test program tst_gfs_data_1.c in the nc_perf directory. The test builds a file just like one output by NOAAs GFS code. It then writes some data to the file, just as NOAA does.
This is similar to the test recently merged to netcdf-fortran (Unidata/netcdf-fortran#265). However, the C test does timing of various choices (for example, compression level and use of shuffle).
See the netcdf-fortran issue for detailed description of the file contents.
The intent is to have a test that uses netCDF just like the NOAA FV3 code, but also allows us to time various choices to see what performs best.
The extra test is only build when --enable-benchmarks is used, for parallel I/O builds.
