re: Issue
The byterange handling of the following URLS fails.
### Problem 1: "https://crudata.uea.ac.uk/cru/data/temperature/HadCRUT.4.6.0.0.median.nc#mode=bytes"
It turns out that byterange in hdf5 has two possible targets: S3 and not-S3 (e.g. a thredds server or the crudata URL above). Each uses a different HDF5 Virtual File Driver (VFD).
I incorrectly set up the byterange code in libhdf5 so that it would choose one or the other of the two VFD's for any netcdf-c library build. The fix is to allow it to choose either one at run-time.
### Problem 2: "https://noaa-goes16.s3.amazonaws.com/ABI-L1b-RadF/2022/001/18/OR_ABI-L1b-RadF-M6C01_G16_s20220011800205_e20220011809513_c20220011809562.nc#mode=bytes,s3"
When given what appears to be an S3-related URL, the netcdf-c library code converts it into a canonical, so-called "path" format. In casing out the possible input URL formats, I missed the case where the host contains the bucket ("noaa-goes16"), but not the region. So the fix was to check for this case.
## Misc. Related Changes
1. Since S3 is used in more than just NCZarr, I changed the automake/cmake options to replace "--enable-nczarr-s3" with "--enable-s3", but keeping the former option as a synonym for the latter. This also entailed cleaning up libnetcdf.settings WRT S3 support
2. Added the above URLS as additional test cases
## Misc. Un-Related Changes
1. CURLOPT_PUT is deprecated in favor to CURLOPT_UPLOAD
2. Fix some minor warnings
## Open Problems
* Under Ubuntu, either libcrypto or aws-sdk-cpp has a memory leak.
re: PR https://github.com/Unidata/netcdf-c/issues/2622
H/T Nathan Potter for finding this.
Apparently the existing library DAP code for supporting
compressed http responses was disabled.
So:
1. enable CURLOPT_ACCEPT_ENCODING by default
2. Add a new HTTP.ENCODE for .dodsrc to allow it to be disabled.
re: https://github.com/Unidata/netcdf-c/issues/2614
Most of the changes are minor comment changes.
But the dispatch table for H5FD has changed, requiring changes
to H5FDhttp.c, which is derived from the HDF5 source file H5FDstdio.c.
The patch is to conditionally modify the dispatch table
to conform to the HDF5-1.14.0 version.
I was able to build and successfully test 1.14 for a reasonable
set of (non-parallel) ./configure options.
