Review request for KDE Runtime, Teo Mrnjavac and Valentin Rusu.


Repository: kde-runtime


Description
-------

Uses the MINOR_VERSION (which until now it was 0) to upgrade the hash from SHA to PBKDF2-SHA512+salt.
I would have loved to completely replace it once the wallet is ported to the new hashing but because
of kwalletd code that is not possible without a bigger rewrite.

There are 2 reasons for this patch:
1-We avoid using our own implementation of SHA
2-We use a modern hashing technique

I'm cooking more patches to use the system user password to open the wallet, we want that password to be
hashed using PBKDF2_SHA512 for security reasons.
