[PATCH] Add ssleep_interruptible()

[Nishanth Aravamudan]

Description: Adds ssleep_interruptible() to allow longer delays to occur
in TASK_INTERRUPTIBLE, similarly to ssleep(). To be consistent with
msleep_interruptible(), ssleep_interruptible() returns the remaining time
left in the delay in terms of seconds. This required dividing the return
value of msleep_interruptible() by 1000, thus a cast to (unsigned long)
to prevent any floating point issues.
