This functionality is required for checkpointing pending signals.

And this should be used along with pread().

I won't argue, but perhaps we should simply postulate that pread()
always dumps siginfo in raw format and avoid the new flag?

I won't argue too:), but I think the flag is more flexiable. The flag
allows to get raw siginfo from read(), it may be useful not only for
checkpoint/restore. pread with offset = 0 is equal to read(), so the
interface with the flag is more clear.

OK, I agree.
