Dennis Heimbigner 8072d1f6bb Modify DAP2 and DAP4 to optionally allow Fillvalue/Variable mismatch
re: issue https://github.com/Unidata/netcdf-c/issues/1151

Modify DAP2 and DAP4 code to handle case when _FillValue type is not
same as the parent variable type.

Specifically:
1. Define a parameter [fillmismatch] to allow this mismatch;
   default is to disallow.
2. If allowed, forcibly change the type of the _FillValue to match
   the parent variable.
3. If allowed Convert the values to match new type
4. Generate a log message
5. if not allowed, then fail

Implementing this required some changes to ncdap_test/dapcvt.c
Also added test cases.

Minor Unrelated Changes:
1. There were a number of warnings about e.g.
   assigning a const char* to a char*. Fix these
2. In nccopy.1, replace .NP with .IP "n"
   (re PR https://github.com/Unidata/netcdf-c/pull/1144)
3. fix minor error in ncdump/ocprint
