Calling this pivotal macro "def-package!" has frequently been a source of confusion. It is a thin wrapper around use-package, and it should be obvious that it is so. For this reason, and to match the naming convention used with other convenience macros/wrappers, it is now use-package!. Also changes def-package-hook! -> use-package-hook! The old macros are now marked obsolete and will be removed when straight integration is merged.
