This function will switch to the proper state for current major
mode. Firstly, the variable `meow-mode-state-list' will be used.
If current major mode derived from any mode from the list,
specified state will be used. When no result is found, give a
test on the commands bound to the keys a-z. If any of the command
names contains \"self-insert\", then NORMAL state will be used.
Otherwise, MOTION state will be used.
Before turning on MOTION state, the original commands will be
remapped. The new keybinding is generated by prepending
`meow-motion-remap-prefix' to the original keybinding.
Note: When this function is called, NORMAL state is already
enabled. NORMAL state is enabled globally when
`meow-global-mode' is used, because in `fundamental-mode',
there's no chance for meow to call an init function."
