Add functions for verifying database signature

Add a pmpgpsig_t struct to the database entry struct and functions for
the lazy loading of database signatures.  Add a function for checking
database signatures, reusing (and generalizing) the code currently used
for checking package signatures.

TODO: The code for reading in signature files from the filesystem is
duplicated for local packages and database and needs refactoring.
