 75fff3ed06 Re-write ROS3 VFD S3 backend to use AWS' C S3 library (#5548) 
* Re-write ROS3 VFD S3 backend to use AWS' C S3 library

Replaces the ROS3 VFD's libcurl-based S3 backend with a new
backend which uses the aws-c-s3 library

Adds support for sourcing credentials from standard AWS
configuration files, environment variables, etc. with a
fallback to anonymous credentials when credentials can't be
found

Adds support for sourcing AWS region from standard AWS
configuration files and environment variables

Adds support for new environment variables HDF5_ROS3_VFD_DEBUG,
HDF5_ROS3_VFD_LOG_LEVEL and HDF5_ROS3_VFD_LOG_FILE for debugging
purposes

Replaces function to load testing credentials in the ros3.c and
s3comms.c tests with new function that delegates to the aws-c-s3
library for better compatibility with standard AWS configuration
files and environment variables

Adds support for s3:// object URIs

Adds HTTP User-Agent header in form of
'libhdf5/<hdf5_version> (vfd:ros3) libaws-c-s3'
