The effect of this change is to make the struct NC structure contain as little file-type specific info as possible. It modifies especially libsrc so that all of the netcdf-3 data that used to be in struct NC is now kept in a separate chunk of data pointed to by the struct NC. This makes all of current protocols consistent: netcdf-3, netcdf-4, and dap.

NC *nc;
Refactored read_scale(), memio_new(), var_create_dataset() and makespecial() to clean up resources properly on failure. Refactored doubly-linked list code for objects in the libsrc4 directory, cleaning up the add/del routines, breaking out the common next/prev pointers into a struct and extracting the add/del operations on them, changed the list of dims to add new dims in the same order as the other types, made all add routines able to optionally return a pointer to the newly created object. Removed some dead code (pg_var(), nc4_pg_var1(), nc4_pg_varm(), misc. small routines, etc) Fixed fill value handling for string types in nc4_get_vara(). Changed many malloc()+strcpy() pairs into calls to strdup(). Cleaned up misc. other minor Coverity issues.

#if 0 /*def USE_PNETCDF*/
Merged in pnetcdf fixes from Greg Sjardema, to make set_fill_mode work with parallel-netcdf, to fully implement parallel-netcdf support for other functions, and to prevent a hang in hdf5 from an eary return in an nc4_put_vara() call. Also fixed an nccopy bug when nc_inq_var_deflate() returns defalate_level of 0, but says the variable is deflated.

[NCF-273]/HZY-708311 Add a new function called nc_inq_format_extended that returns more detailed format information (vis-a-vis nc_inq_format) about an open dataset. Note that the netcdf API will present the file as if it had the format specified by nc_inq_format. The true file format, however, may not even be a netcdf file; it might be DAP, HDF4, or PNETCDF, for example. This function returns that true file type. It also returns the effective mode for the file. signature: nc_inq_format_extended(int ncid, int* formatp, int* modep) where * ncid is the NetCDF ID from a previous call to nc_open() or nc_create(). * formatp is a pointer to a location for returned true format. * modep is a pointer to a location for returned mode flags. Refer to the actual list in the file netcdf.h to see the currently defined set. Also added test cases (tst_formatx*).
