Make use of new evil variable evil-disable-insert-state-bindings. This
is better because we are not copying evil code to get hybrid state to
work. We should not need to worry about tracking upstream evil changes
with this version of hybrid mode.
The only effect I can think of with this change is that there is no
longer a distinct hybrid-map, since there is no longer a distinct hybrid
state. This means that, for example, (evil-define-key 'hybrid ...)
will throw an error. You can either use (evil-define-key 'insert ...) or
the preferred (global-set-key ...). The latter is preferred because the
purpose of hybrid mode is to not interfere with Emacs bindings in insert
state.
Use post-init-evil function to load
It's a bit safer than with-eval-after-load, in case evil gets loaded
before its init function is called.
Add entry and exit hooks
Add temporary wrapper to evil-define-key
This is so that calls like (evil-define-key 'hybrid ...) do not fail
after switching over. Instead issue a warning for all such instances and
bind using define-key instead.
Also define evil-hybrid-state-map and make it the parent of
evil-insert-state-map this will prevent calls like (define-key
evil-hybrid-state-map ...) from failing.
These are both temporary and are only intended to smooth the transition
to the new version of hybrid-mode.
