Please do not (attempt to) post more replies to v1, as it kicks up a
storm of angry MTAs.

I'll include (something like) this in some "how to use" documentation
I'm working on separately.

With no callers left of prandom_u32() and prandom_bytes(), remove these
deprecated wrappers.

The prandom_bytes() function has been a deprecated inline wrapper around
get_random_bytes() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function.

Rather than truncate a 32-bit value to a 16-bit value or an 8-bit value,
simply use the get_random_{u8,u16}() functions, which are faster than
wasting the additional bytes from a 32-bit value.

crypto/testmgr.c | 8 +++
Rather than incurring a division or requesting too many random bytes for
the given range, use the prandom_u32_max() function, which only takes
the minimum required bytes from the RNG and avoids divisions.
