Improve exit statuses and error messages in pacman-key
Return codes from gpg commands are currently lost. This adds the functionality of taking non-zero exit statuses from gpg. This includes error reporting for all gpg commands that are run individually, run in a loop, and run through a pipe. Includes the check_keyids_exist function which verifies a key exists locally prior to attempted local manipulation of the key. If a gpg command has a non-zero status, pacman-key will now exit with a non-zero status. It will print a gettext error message of gpg's failure.
