[issue20658] os.environ.clear() fails with empty keys (posix.unsetenv)

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Are there supported platforms on which setenv() is not supported? When we will migrate to setenv(), an argument check will be not needed.

In any case I think we should wrap unsetenv() in os.environ.clear() so that it should try to remove all environment variables even if some calls of unsetenv() fails.
