Restore compatibility with pre-5.9 Keccak calculation
Commit 12c5264d9add1826d543c36d893db77262195fc6 fixed the calculation of
SHA-3 in QCryptographicHash: we were previously calculating Keccak.
Unfortunately, turns out that replacing the algorithm wasn't the best
idea: there are people who need to compare with the result obtained from
a previous version of Qt and stored somewhere. This commit restores the
enum values 7 through 10 to mean Keccak and moves SHA-3 to 12 through
15. The "Sha3_nnn" enums will switch between the two according to the
QT_SHA3_KECCAK_COMPAT macro.
[ChangeLog][Important Behavior Changes] This version of Qt restores
compatibility with pre-5.9.0 calculation of QCryptographicHash
algorithms that were labelled "Sha3_nnn": that is, applications compiled
with old versions of Qt will continue using the Keccak algorithm.
Applications recompiled with this version will use SHA-3, unless
QT_SHA3_KECCAK_COMPAT is #define'd prior to #include
<QCryptographicHash>.
[ChangeLog][Binary Compatibility Note] This version of Qt changes the
values assigned to enumerations QCryptographicHash::Sha3_nnn.
Applications compiled with this version and using those enumerations
will not work with Qt 5.9.0 and 5.9.1, unless QT_SHA3_KECCAK_COMPAT is
defined.
