68e6d64fe3 QString: fix off-by-one error
The check for having N valid characters is ptr + N <= end, because
ptr + N == end indicates that we have exactly N characters in the
string.

43ea15d01c macOS + FreeType: Properly distinguish memory fonts from file fonts

NSCTFontFileURLAttribute with a value such as:

 file://iNmEmOrYcGfOnT_0x101d3c3a0#postscript-name=New

Which means we can't use the presence of the kCTFontURLAttribute to
determine that we're dealing with a file font. Instead we check for
our custom kQtFontDataAttribute first, which is only set for memory
fonts.

93e0ff037e QJsonDocument: Validate also zero-length objects
The added test case is the binary JSON equivalent of

    {"a":{"š":null}}

with two modifications. First, the length of the string "š" has been corrupted
to 0xFFFFFF00. Second and more import, the Base::size field of the inner object
has been reset to 0.

On its own the first modification would normally trigger a validation error.
However, due to the second modification the Value::usedStorage for the inner
object evaluates to 0, completely disabling all further validation of the
object's contents.

Attempting to convert this binary JSON into standard JSON will lead to the JSON
writer trying to construct a QString of length 0xFFFFFF00.

Fixed by validating also objects with usedStorage == 0.

c9b46a130e qtestlib: restore qWaitForWindowActive() its original semantics
This patch removes a bad hack for Unity issue described in QTBUG-67757.
The workaround from 243a0660e1 caused
even more problems, see QTBUG-63542.

Besides causing more problems, the usage of this hack was inconsistent.
The goal was to get stable geometry before continuing further in the test
function. The same logic should have been used in qWaitForWindowExposed().
It was never documented that only qWaitForWindowActive() has this tweak.
Also this hack was needed only for Unity, instead being unconditionally
executed for all platforms.
