input: fix sleep support, kill bad ifdefs, cleanup comments

[Pavel Machek <pavel@ucw.cz>]

Hi!

It is possible to kill few #ifdefs from input.c, so I did that.

Comments far to the left hurt readability in my eyes (I believe
input.c has *way* too much comments, too, but...).

Fixed serio.c so its sleep support actually works.
