## S3 Related Fixes * Add comprehensive support for specifying AWS profiles to provide access credentials. * Parse the files "~/.aws/config" and "~/.aws/credentials to provide credentials for the HDF5 ROS3 driver and to locate default region. * Add a function to obtain the currently active S3 credentials. The search rules are defined in docs/nczarr.md. * Provide documentation for the new features. * Modify the struct NCauth (in include/ncauth.h) to replace specific S3 credentials with a profile name. * Add a unit test to test the operation of profile and credentials management. * Add support for URLS of the form "s3://<bucket>/<key>"; this requires obtaining a default region. * Allows the specification of profile and/or region in a URL of the form "#mode=nczarr,...&aws.region=...&aws.profile=..." ## Misc. Fixes * Move the ezxml code to libdispatch so that it can be used both by DAP4 and nczarr. * Modify nclist to provide a deep clone operation. * Modify ncuri to provide a deep clone operation. * Modify the .rc file format to allow the specification of a path to be tested when looking for an entry in the .rc file. * Ensure that the NC_rcload function is called. * Modify nchttp to support setting request headers.
