QTextEngine: Protect against integer overflow with huge texts
QPlainTextEdit would crash when adding a string of 136 348 169
characters, due to the integer overflow checks being done with int
variables.
Perform intermediate calculations and size checks with qsizetype
instead of int. This commit contains a slight modification of the fix
contributed by Adam Clarke in the bug report. Note that the size check
casts to size_t to cover the 32-bit case where qsizetype is qint32.
Fixes: QTBUG-119611
Pick-to: 6.7
