lib.pm.*.install_packages(): Add functions
Currently, jw-pkg install is sometimes left to the high-level package manager, which is allowed to install dependencies along, and that's sometimes unwanted, but there's no backend in the low-level package manager module lib.pm to allow specifying that. This commit adds it: lib.pm.*.install_packages(). The functions install a list of local package files using the low-level package managers rpm / dpkg, bypassing the high-level package managers yum / apt / zypper. pm.rpm runs rpm -U and pm.dpkg runs dpkg -i. Every file is classified against the installed state of its package, queried by name: a file for a package that is not installed is installed fresh, a file with another version installed is upgraded, and a file whose version is already installed is reinstalled when force is set and skipped otherwise. On rpm, plain -U refuses a package that is already installed, and --reinstall aborts the transaction when a file of the incoming package differs from the installed one, so the upgrades run before the reinstalls and the same-version files need force. With only_update, a file for a package that is not installed raises before anything is installed. The dpkg route is gated on an apt simulation, because dpkg -i leaves a half-configured package when a dependency is missing: the simulation runs first and the install is refused when it would install or remove anything but the given files' own packages.
