timers: Rename del_timer() to timer_delete()

Browse Source 
[ Upstream commit bb663f0f3c ]

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.
