Allow frontend access to signature verification information
Show output in -Qip for each package signature, which includes the UID string from the key ("Joe User <joe@example.com>") and the validity of said key. Example output: Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>" Unknown signature from "<Key Unknown>" Invalid signature from "Dan McGee <dpmcgee@gmail.com>" Also add a backend alpm_sigresult_cleanup() function since memory allocation took place on this object, and we need some way of freeing it. Signed-off-by: Dan McGee <dan@archlinux.org>
