bug#24959: 26.0.50; cancel-timer: void-variable timer

[Oleg Sivokon]

Eli, Lars,

I know what the timer handler is. I'm not sure how to interpret the
backtrace then: did it or did it not enter the cancel-timer function?
I thought it did, and this is why I filed this ticket.

More background (this applies if the backtrace says that cancel-timer
was not entered):
The code in the handler relies on the code that sets up the timer to
create a special variable "timer". This variable is created by calling
setq (but no defvar). setq used to make variable special, if it wasn't
already let-bound. Now it seems like this behavior has changed. Does
this make sense?
