Revise CACERTS autodetection logic, ensure that CACERTS/CAPATH is readable/directory, add undocumented CAPATH env override.
This takes advantage of the new --cafile logic to avoid running CACERTS autodetection when a file is provided on the command line. It then ensures the readability of that file, whether provided or autodetected. This also adds an undocumented CAPATH environment variable alternative to --capath, to go along with the existing undocumented CACERTS environment variable alternative to --cafile, to provide legacy support for preexisting users.
