- Refresh spec-file.
- Update to 1.0.15.
* Release notes: https://github.com/jedisct1/libsodium/releases/tag/1.0.15
* The default password hashing algorithm is now Argon2id.
* The pwhash_str_verify() function can still verify Argon2i hashes without any changes,
and pwhash() can still compute Argon2i hashes as well.
* The aes128ctr primitive was removed. It was slow, non-standard, not authenticated,
and didn't seem to be used by any opensource project.
* Argon2id required at least 3 passes like Argon2i, despite a minimum of 1
as defined by the OPSLIMIT_MIN constant. This has been fixed.
* The secretstream construction was slightly changed to be consistent with forthcoming variants.
* The Javascript and Webassembly versions have been merged, and the module now returns
a .ready promise that will resolve after the Webassembly code is loaded and compiled.
* Note that due to these incompatible changes, the library version major was bumped up.
