Tweak the new evutil_weakrand_() code
Make its state actually get seeded.
Document it more thoroughly.
Turn its state into a structure.
Fix a bug in evutil_weakrand_range_() where it could return the top of
the range.
Change its return type to ev_int32_t.
Add a quick unit test to make sure that the value of
evutil_weakrand_range_() is in range.
