I see that there is no way to set CURLOPT_CONNECTTIMEOUT,
but there is support for CURLOPT_TIMEOUT.
So, accept the line 'HTTP.CONNECTTIMEOUT'
in .rc file to allow user to set CURLOPT_CONNECTTIMEOUT.

The situation with the various DAP (and other) remote test
servers is currently in a state of flux. For example, Unidata
admin is planning to forcibly shift the remote test server to
remotetest.unidata.ucar.edu soon. In addition, the server
test.opendap.org has shown some recent instability.
The result is that various DAP (and byterange) tests can fail
unexpectedly. This is an irritant to users and reveals nothing
about test sucess or failure.
Solve by modifying tests to report server inaccessibility and
otherwise pretend to succeed.
This puts an onus on Unidata to detect such server failures, but
will not cause users to see spurious failures. [Note. Do similar
fix for netcdf-java]. The check is:
1. export SETX=1 to cause all the shell scripts to trace
2. search the log files for the phrase "WARNING" (in upper case)
and see if it is complaining about not finding a server.
Misc. Changes
-------------
1. Added a pingurl program to see if a server was up.
2. modified some test case url targets

If you plan to use any of the netcdf_XXX.h files, then it it is assumed
that you first include netcdf.h, followed by any netcdf_XXX.h files
you need. The EXTERNL (and other things) are defined in netcdf.h
so they should be available for use by the netcdf_XXX.h files.
This PR ensures that the above assumption is true. It also adds
some comments to that effect to the start of the netcdf_xxx.h files.
* For URL paths, the new approach essentially centralizes all information
in the URL into the "#mode=" fragment key and uses that value
to determine the dispatcher for (most) URLs.
* The new approach has the following steps:
1. canonicalize the path if it is a URL.
2. use the mode= fragment key to determine the dispatcher
3. if dispatcher still not determined, then use the mode flags
argument to nc_open/nc_create to determine the dispatcher.
4. if the path points to something readable, attempt to read the
magic number at the front, and use that to determine the dispatcher.
this case may override all previous cases.
* Misc changes.
1. Update documentation
2. Moved some unit tests from libdispatch to unit_test directory.
3. Fixed use of wrong #ifdef macro in test_filter_reg.c
[I think this may fix an previously reported esupport query].
Partially address: https://github.com/Unidata/netcdf-c/issues/1056
Currently, some of the entries in the dispatch table
are conditional'd on USE_NETCDF4.
As a step in upgrading the dispatch table for use
with user-defined tables, we remove that conditional.
This means that all dispatch tables must implement the
netcdf-4 specific functions even if only to make them
return NC_ENOTNC4. To simplify this, a set of default
functions are defined in libdispatch/dnotnc4.c to provide this
behavior. The file libdispatch/dnotnc3.c is also relevant to
this.
The primary fix is to modify the various dispatch tables to
remove the conditional and use the functions in
libdispatch/dnotnc4.c as appropriate. In practice, all of the
existing tables are prepared to handle this, so the only
real change is to remove the conditionals.
Misc. Unrelated fixes
1. Fix some annoying warnings in ncvalidator.
Notes:
1. This has not been tested with either pnetcdf or hdf4 enabled.
When those are enabled, it is possible that there are still
some conditionals that need to be fixed.
