Subject: Turn gpg commands into functions in pacman-key

Adds functions for every gpg command. By pulling out the gpg commands from the
"program start" section, additional commands can be run before or after a
specific gpg command without adding additional clutter to the function call
section.

Adds an explicit exit status of 0 to prevent arithmetic expansions from
returning non-zero, thereby falsely causing pacman-key to have a non-zero exit
status.

This change creates the framework for additional error messages and better
exit statuses being added to every pacman-key gpg call.
