Detected by clang scan-build static code analyzer.

* Don't attempt to free an uninitialized gpgme key variable
* Initialize answer variable before asking frontend a question
* Pass by reference instead of value if uninitialized fields are
  possible in download signal handler code
* Ensure we never call strlen() on NULL payload->remote_name value
