Deprecate qMemCopy/qMemSet in favour of their stdlib equivilents.

Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these
functions just to avoid an include, except to pay for it with worse runtime
performance.

On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15%
faster(!) than adding an additional call to qMemSet. The advantage on sizes
above that is unmeasurable.

For qMemCopy, the benefits are a little more modest: 16-7%.
