netcdf-c/libdap4/d4cvt.c
Dennis Heimbigner 3db4f013bf Primary change: add dap4 support 
Specific changes:
1. Add dap4 code: libdap4 and dap4_test.
   Note that until the d4ts server problem is solved, dap4 is turned off.
2. Modify various files to support dap4 flags:
	configure.ac, Makefile.am, CMakeLists.txt, etc.
3. Add nc_test/test_common.sh. This centralizes
   the handling of the locations of various
   things in the build tree: e.g. where is
   ncgen.exe located. See nc_test/test_common.sh
   for details.
4. Modify .sh files to use test_common.sh
5. Obsolete separate oc2 by moving it to be part of
   netcdf-c. This means replacing code with netcdf-c
   equivalents.
5. Add --with-testserver to configure.ac to allow
   override of the servers to be used for --enable-dap-remote-tests.
6. There were multiple versions of nctypealignment code. Try to
   centralize in libdispatch/doffset.c and include/ncoffsets.h
7. Add a unit test for the ncuri code because of its complexity.
8. Move the findserver code out of libdispatch and into
   a separate, self contained program in ncdap_test and dap4_test.
9. Move the dispatch header files (nc{3,4}dispatch.h) to
   .../include because they are now shared by modules.
10. Revamp the handling of TOPSRCDIR and TOPBUILDDIR for shell scripts.
11. Make use of MREMAP if available
12. Misc. minor changes e.g.
	- #include <config.h> -> #include "config.h"
	- Add some no-install headers to /include
	- extern -> EXTERNL and vice versa as needed
	- misc header cleanup
	- clean up checking for misc. unix vs microsoft functions
13. Change copyright decls in some files to point to LICENSE file.
14. Add notes to RELEASENOTES.md
