b65c1ccfe1 Change i to unsigned in get_generic_seed().
This is clearer than comparing against an unsigned number to force an unsigned
comparison that we need.

b7fa5c5abb random_seed: allow to block on /dev/random
If both /dev/random and /dev/urandom failed to return data, an
uninitialised value might be returned.  Since most systems have a
non-blocking /dev/urandom or have /dev/random with similar properties,
the chance of blocking is minimal, and the alternative of returning
non-random data is worse.

Attempt to read from /dev/urandom and /dev/random with O_NONBLOCK set.
If neither succeeds, proceed with fallbacks.
