fbcdf78cbd Simplify wyhash and improve speed 
This removes the exposed stateless variant since the standard variant
has similar speed now.

Using `./benchmark --filter wyhash --count 1024`, the speed change has
changed from:

a610352271 std/hash: Revert crc32 api change 
This is user specified and the user doesn't necessarily have to use one
of the provided polynomials declared hence we can't use an enum.

Thanks @daurnimator for catching this.

16fa255f48 Inline full slice hashing 
This gives moderate speed improvements when hashing small keys.
The crc/adler/fnv inlining did not provide enough speed up to warrant
the change.

fixups 
* getrandom libc prototypes had the wrong return type
 * `total_read` local variable was unnecessary since the sub-slice
   buffer has a length
 * I was able to get rid of all the integer casts
 * the err == 0 check can be a switch case
 * add missing `return` statement
