2. modify oc2/ocrc.c rcfilenames to look for .ocrc before .dodsrc.
3. Modify testauth.sh to avoid using names that might already
exist for cookies file and netrc file. Still must use .ocrc
to test for local/home search.
4. Modify testauth.sh to save and restore any file it creates
that already exists.
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"
should be under ENABLE_DAP_REMOTE_TESTS.
Fixed to make sure that this is so.
Also attempted to fix ncdap_test/CMakeLists.txt,
but probably got it wrong.

2. Attempted to reduce the number of conversion errors
when -Wconversion is set. Fixed oc2, but
rest of netcdf remains to be done.

3. When doing #2, I discovered an error in ncgen.y
that has remained hidden. This required some other
test case fixes.
1. In nc4hdf.c, had a variable declaration located such
that Visual Studio complained and threw an error. Moved
to head of function.
2. Visual Studio was complaining about variable declarations
being made after OCVERIFY/OCDEREF macros.
