re: Issue https://github.com/Unidata/netcdf-c/issues/2190
The primary purpose of this PR is to improve the utf8 support
for windows. This is persuant to a change in Windows that
supports utf8 natively (almost). The almost means that it is
still utf16 internally and the set of characters representable
by utf8 is larger than those representable by utf16.
This leaves open the question in the Issue about handling
the Windows 1252 character set.
This required the following changes:
1. Test the Windows build and major version in order to see if
native utf8 is supported.
2. If native utf8 is supported, Modify dpathmgr.c to call the 8-bit
version of the windows fopen() and open() functions.
3. In support of this, programs that use XGetOpt (Windows versions)
need to get the command line as utf8 and then parse to
arc+argv as utf8. This requires using a homegrown command line parser
named XCommandLineToArgvA.
4. Add a utility program called "acpget" that prints out the
current Windows code page and locale.
Additionally, some technical debt was cleaned up as follows:
1. Unify all the places which attempt to read all or a part
of a file into the dutil.c#NC_readfile code.
2. Similary unify all the code that creates temp files into
dutil.c#NC_mktmp code.
3. Convert almost all remaining calls to fopen() and open()
to NCfopen() and NCopen3(). This is to ensure that path management
is used consistently. This touches a number of files.
4. extern->EXTERNL as needed to get it to work under Windows.
re: e-support EOT-483791
* Add a new set of remote tests based on using the thredds-test server.
* Improve error reporting when server requests fail.
* Fix handing of _NCProperties attribute
re: esupport 31942
* Add a new set of remote tests based on using the opendap hyrax server
* Re-enable --enable-dap-remote-tests as default on
* Make it possible to query the DMR separate from the DAP
so that it is possible to delay reading data until it is actually
requested. This make things like ncdump -h much more efficient.
* Fix handling of <Map>s in DMRs.
* Fix some memory leaks

This PR partially fixes memory leaks in the netcdf-c library,
in the ncdump utility, and in some test cases.
The netcdf-c library now runs memory clean with the assumption
that the --disable-utilities option is used. The primary remaining
problem is ncgen. Once that is fixed, I believe the netcdf-c library
will run memory clean with no limitations.
Notes
-----------
1. Memory checking was performed using gcc -fsanitize=address.
Valgrind-based testing has yet to be performed.
2. The pnetcdf, hdf4, and examples code has not been tested.
Misc. Non-leak changes
1. Make tst_diskless2 only run when netcdf4 is enabled (issue 1162)
2. Fix CmakeLists.txt to turn off logging if ENABLE_NETCDF_4 is OFF
3. Isolated all my debug scripts into a single top-level directory
called debug
4. Fix some USE_NETCDF4 dependencies in nc_test and nc_test4 Makefile.am
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
