A new define for better vectorized compositioning had a mistake that
caused some sources to be converted to grayscale when composited.
Added two 10 bit per channel formats to the lancelot test to catch
regressions in the future.

Instead of quint64 use uint64_t in order to avoid errors like
error: invalid conversion from 'quint64* {aka long long unsigned int*}' to
'const uint64_t* {aka const long unsigned int*}'
Unify const usage for LOAD and switch to C++ casts.

Adds overloaded functions for some common operations used for
compositing, and use those together with specialized loading/storing.
QRgba64 is represented as a quint64, so most of the time it lives in
the integer registers. By overloading functions to return SIMD data
types, the temporary values are kept in SIMD registers (so no more
unnecessary transfers between the registers, which can cost a lot on
ARM). It also allows the compiler to do better TBAA and optimizations.
Another benefit is that the loop bodies are smaller, giving them a
higher chance to fit in the micro-op cache of modern CPUs.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

Also changes the way the SSE2 composition modes are inserted into the table,
so it is handled like all the other tables and doesn't require duplicating most
of the table.
