libalpm/package.c : add _alpm_pkgname_pkg_cmp function.
_alpm_pkgname_pkg_cmp(pkgname, pkg) returns true iff pkg's name is pkgname. This is useful if you want to remove a package from pmpkg_t* list, and you want to search for package name. This allows cleaning the -Ru code a bit, by removing the need of a dummy pkg. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
