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.
