Add the ability to set some additional curlopt values via .daprc (aka .dodsrc).
This effects both DAP2 and DAP4 protocols.

1. CURLOPT_BUFFERSIZE: Relevant to [1]. Allow user to set the read/write
buffersizes used by curl.
This is done by adding the following to .daprc (aka .dodsrc):
HTTP.READ.BUFFERSIZE=n
where n is the buffersize in bytes. There is a built-in (to curl)
limit of 512k for this value.
2. CURLOPT_TCP_KEEPALIVE (and CURLOPT_TCP_KEEPIDLE and CURLOPT_TCP_KEEPINTVL):
Relevant (maybe) to [2] and [3]. Allow the user to turn on KEEPALIVE
This is done by adding the following to .daprc (aka .dodsrc):
HTTP.KEEPALIVE=on|n/m
If the value is "on", then simply enable default KEEPALIVE. If the value
is n/m, then enable KEEPALIVE and set KEEPIDLE to n and KEEPINTVL to m.
url parameter handling, the parameter
lookup code was ignoring parameters
because I was giving it a url stripped
of parameters instead of the one with
parameters.
This code change fixes the parameter processing
so it again used the correct url.

docs/OPeNDAP.dox#section Defined Client Parameters
The problem was that for opendap, it is possible to use keywords
as identifiers
when there is no ambiguity. However, the DAP2
parser lost the case of the identifier used the lower case version.
Fix is to use the actual text of the symbol when it is used as an identifier.
Also added a test case for this (kwcase.*).
Additionally cleaned up some misc. dap2 testing problems.
1. ncdap_test/tst_ncdap3.sh was using an empty test set.
restored the testing of datasets.
2. as a consequence of #1, some tests needed to be updated with minor
tweeks.
3. fix dapmerge to handle multiple DODS_EXTRAS attributes.
4. modify buildattribute to suppress nul characters and terminate
the name at the first nul.
5. clean up various test scripts to remove residual, unused
references to obsolete netcdf-4 translation.
6. export e.g. NCDUMP from test_common.in so that non-top-level
shell scripts can access it.
1. When running under windows (as opposed to cygwin)
we need to make sure to not user /cygdrive/ file paths.
This was ocurring in libdap4/d4read.c, but may occur
elsewhere.
2. Shell scripts in the git repo are not being checked-out
with the executable mode set. Had core.filemode set to false.
Was a major hassle to fix.
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
User request to have all orphaned DAP2 attributes kept as netcdf
global attributes. This is primarily a change in the oc code
nplus testcase dataset changes.
Result may be inconsistent with netcdf-Java output.
This supports better authorization
handling for DAP requests, especially redirection
based authorization. I also added a new test case
ncdap_tests/testauth.sh.
Specifically, suppose I have a netrc file /tmp/netrc
containing this.
machine uat.urs.earthdata.nasa.gov login xxxxxx password yyyyyy
Also suppose I have a .ocrc file containing these lines
HTTP.COOKIEJAR=/tmp/cookies
HTTP.NETRC=/tmp/netrc
Assume that .ocrc is in the local directory or HOME.
Then this command should work (assuming a valid login and password).
ncdump -h "https://54.86.135.31/opendap/data/nc/fnoc1.nc"
