* keymap.el:
* keymap.el (event-apply-alt-modifier):
* keymap.el (event-apply-super-modifier):
* keymap.el (event-apply-hyper-modifier):
* keymap.el (event-apply-shift-modifier):
* keymap.el (event-apply-control-modifier):
* keymap.el (event-apply-meta-modifier):
* keymap.el (event-apply-modifiers): New.
* keymap.el (event-apply-modifier): Implement in terms of

Rework #'event-apply-modifier to take a list of modifiers, and
change its name appropriately. Keep the old name around, too.
