Changes v2->v3:
- Handle get_random_int() conversions too, which were overlooked before,
  in the same way as the rest.

Hi folks,

This is a five part treewide cleanup of random integer handling. The
rules for random integers are:

- If you want a secure or an insecure random u64, use get_random_u64().
- If you want a secure or an insecure random u32, use get_random_u32().
  * The old function prandom_u32() has been deprecated for a while now
    and is just a wrapper around get_random_u32(). Same for
    get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16().
- If you want a secure or an insecure random u8, use get_random_u8().
- If you want secure or insecure random bytes, use get_random_bytes().
  * The old function prandom_bytes() has been deprecated for a while now
    and has long been a wrapper around get_random_bytes().
- If you want a non-uniform random u32, u16, or u8 bounded by a certain
  open interval maximum, use prandom_u32_max().
  * I say "non-uniform", because it doesn't do any rejection sampling or
    divisions. Hence, it stays within the prandom_* namespace.

These rules ought to be applied uniformly, so that we can clean up the
deprecated functions, and earn the benefits of using the modern
functions. In particular, in addition to the boring substitutions, this
patchset accomplishes a few nice effects:

- By using prandom_u32_max() with an upper-bound that the compiler can
  prove at compile-time is ≤65536 or ≤256, internally get_random_u16()
  or get_random_u8() is used, which wastes fewer batched random bytes,
  and hence has higher throughput.

- By using prandom_u32_max() instead of %, when the upper-bound is not a
  constant, division is still avoided, because prandom_u32_max() uses
  a faster multiplication-based trick instead.

- By using get_random_u16() or get_random_u8() in cases where the return
  value is intended to indeed be a u16 or a u8, we waste fewer batched
  random bytes, and hence have higher throughput.

So, based on those rules and benefits from following them, this patchset
breaks down into the following five steps, which were done mostly
manually:

1) Replace `prandom_u32() % max` and variants thereof with
   prandom_u32_max(max).

2) Replace `(type)get_random_u32()` and variants thereof with
   get_random_u16() or get_random_u8(). I took the pains to actually
   look and see what every lvalue type was across the entire tree.

3) Replace remaining deprecated uses of prandom_u32() and
   get_random_int() with get_random_u32(). 

4) Replace remaining deprecated uses of prandom_bytes() with
   get_random_bytes().

5) Remove the deprecated and now-unused prandom_u32() and
   prandom_bytes() inline wrapper functions.

I was thinking of taking this through my random.git tree (on which this
series is currently based) and submitting it near the end of the merge
window, or waiting for the very end of the 6.1 cycle when there will be
the fewest new patches brewing. If somebody with some treewide-cleanup
experience might share some wisdom about what the best timing usually
winds up being, I'm all ears.

Please take a look! At "379 insertions(+), 422 deletions(-)", this
should be a somewhat small patchset to review, despite it having the
scary "treewide" moniker on it.

Thanks,
Jason
