Follow-up fixes for SHA-2 patch (commit 749a9e20c).

This changes the check for valid characters in the salt string to
only allow plain ASCII letters and digits.  The previous coding was
locale-dependent which doesn't really seem like a great idea here;
moreover it could not work correctly in multibyte encodings.

This fixes a careless pointer-use-after-pfree, too.

Fix memory leaks in px_crypt_shacrypt().

Per Coverity.  I don't think these are of any actual significance
since the function ought to be invoked in a short-lived context.
Still, if it's trying to be neat it should get it right.

Also const-ify a constant and fix up typedef formatting.

This adapts the publicly available reference implementation on
https://www.akkadia.org/drepper/SHA-crypt.txt and adds the new hash
algorithms sha256crypt and sha512crypt to crypt() and gen_salt()
respectively.
