libsodium: updated to 1.0.17

Version 1.0.17
- Bug fix: sodium_pad() didn't properly support block sizes >= 256 bytes.
- JS/WebAssembly: some old iOS versions can't instantiate the WebAssembly
module; fall back to Javascript on these.
- JS/WebAssembly: compatibility with newer Emscripten versions.
- Bug fix: crypto_pwhash_scryptsalsa208sha256_str_verify() and
crypto_pwhash_scryptsalsa208sha256_str_needs_rehash() didn't return
EINVAL on input strings with a short length, unlike their high-level
counterpart.
- Added a workaround for Visual Studio 2010 bug causing CPU features
not to be detected.
- Portability improvements.
- Test vectors from Project Wycheproof have been added.
- New low-level APIs for arithmetic mod the order of the prime order group:
crypto_core_ed25519_scalar_random(), crypto_core_ed25519_scalar_reduce(),
crypto_core_ed25519_scalar_invert(), crypto_core_ed25519_scalar_negate(),
crypto_core_ed25519_scalar_complement(), crypto_core_ed25519_scalar_add()
and crypto_core_ed25519_scalar_sub().
- New low-level APIs for scalar multiplication without clamping:
crypto_scalarmult_ed25519_base_noclamp() and
crypto_scalarmult_ed25519_noclamp(). These new APIs are especially useful
for blinding.
- sodium_sub() has been implemented.
- Support for WatchOS has been added.
- getrandom(2) is now used on FreeBSD 12+.
- The nonnull attribute has been added to all relevant prototypes.
- More reliable AVX512 detection.
- Javascript/Webassembly builds now use dynamic memory growth.
