client: Keep committed buffers busy while unexposed

After a frame callback timeout, safeCommit() may receive a committed
buffer while the window is unexposed. Clearing its busy state lets
the backing store reuse it before wl_buffer.release. The next commit
is ignored and the window stops updating.

Committed buffers now remain busy until the compositor releases them.

QMap: mark referenceHoldingDetach helpers as [[nodiscard]]

Equivalent to QMultiMap, the purpose of these functions is to keep the
pre-detach copy - and thus references to key/value that may alias the
map - alive in a caller-side local. Discarding the result silently
defeats the safety and risks a dangling reference.

Note that these methods have public visibility even though they are
undocumented and in practice only used internally.

QEasingCurve: fix named constructor from cubic bezier points

Named constructors in Qt start with "from", and QPointF is a small,
trivially copied type that should be passed by value.

Add a symmetric \sa to the addCubicBezierSegment documentation.
