9e07ffa4e4 librhash: Avoid signed left-shift overflow in sha256 
Fix `rhash_sha256_final` to use unsigned integers for left shifting to
avoid the possibility of undefined overflow behavior.

fc2cb74fee librhash: Implement bswap_32 as a function even in strict C90 mode 
We cannot fall back to the macro implementation because some call sites
may call it with an argument like `*ptr++` that has side effects.

bb01f20e99 librhash: Disable warnings to avoid changing 3rd party code

31bb727f3b librhash: Build the library within CMake 
Update `ustd.h` to include KWSys Large File Support configuration so
that consistent stream libraries are used (on AIX with XL).

Add a `cm_rhash.h` header to include the CMake-provided copy of the
`rhash.h` header from CMake sources.

53048afa8d librhash: Remove source fragments not needed for CMake 
We only need a subset of the hash algorithms supported by librhash.
Add preprocessor conditionals to remove source fragments that we do
not need.  Write an alternative algorithm enumeration that matches
the indexing on our reduced array.

Also remove a few fragments outright.
