signing: add a process and retry loop for database signatures
In reality, there is no retrying that happens as of now because we don't have any import or changing of the keyring going on, but the code is set up so we can drop this in our new _alpm_process_siglist() function. Wire up the basics to the sync database validation code, so we see something like the following: $ pacman -Ss unknowntrust error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust error: database 'core' is not valid (invalid or corrupted database (PGP signature)) $ pacman -Ss missingsig error: core: missing required signature error: core: missing required signature error: database 'core' is not valid (invalid or corrupted database (PGP signature)) Yes, there is some double output, but this should be fixable in the future.
