helper function for resolvedeps: search for dep satisfier in dbs

Parameters

handle	the context handle
dep	is the dependency to search for
dbs	are the databases to search
excluding	are the packages to exclude from the search
prompt	if true, ask an alpm_question_install_ignorepkg_t to decide if ignored packages should be installed; if false, skip ignored packages.

Returns

the resolved package
