prefix-key.

The following changes have been made to provide command remapping:
- define-key now accepts a command name as the KEY argument.
This identifies the command to be remapped in the specified keymap.
This is equivalent to specifying the command name as the only
element of a vector, e.g [kill-line], except that when KEY is a
symbol, the DEF argument must also be a symbol.
- Command remappings are defined using `define-key' with a prefix-key
`remap', i.e. `(define-key MAP [remap CMD] DEF)' remaps command CMD
to definition DEF in keymap MAP. The definition is not limited to
another command; it can be anything accepted for a normal binding.
- In calls from Lisp, global-set-key, global-unset-key, local-set-key,
and local-unset-key also accept a command name as the KEY argument.
- The new function `remap-command' returns the binding for a remapped
command in the current keymaps, or nil if it isn't remapped.
- key-binding now remaps interactive commands unless the optional
third argument NO-REMAP is non-nil. It also accepts a command name
as the KEY argument.
- lookup-key now accepts a command name as the KEY argument.
third argument NO-REMAP is non-nil.
- where-is-internal now returns nil for a remapped command (e.g.
kill-line if my-mode is enabled), and the actual key binding for
