  The timer related functions do not have a strict timer_ prefixed namespace
which is really annoying.

Rename del_timer() to timer_delete() and provide del_timer()
as a wrapper. Document that del_timer() is not for new code.

BTW, I did a: git "grep del_timer Documentation" and there's a lot of
references to the old name. Perhaps you want to update those too (for both
del_timer() and del_timer_sync()).
