Fix encoding of localized messages

QDebug::operator<<(const char*) uses QString::fromUtf8(), while
qPrintable(str) returns QString::toLocal8Bit(). This messes up e.g. the
Russian translations.

Revert "Dynamic GL support in Quick1's ShaderEffectSource"

Will need to change to QOpenGLContext::currentContext()->isES()
once the qtbase changes are in.

This reverts commit 3eeaf987123f73ad7a4745745d9e7c70f30942cd.

Correct QDeclarativeTextEdit::positionToRectangle().

d->yoff is the content offset when the content is not top aligned.
This means that positionToRectangle() returned incorrect values when
the content was bottom or vertical center aligned. In other words,
it didn't apply the offset but gave coordinates from the beginning of
the content instead of from the beginning of the item.
