qsql.h - no such file or directory error when compiling for Qt 6.5.2

[githubuser0xFFFF]

Hi,

I just managed to build the library for Qt 6.5.2 with MinGW 64 - thank you for supporting Qt6. There was only one single problem with the headers generated by the pythonqt_generator.exe for Qt 6.5.2. When building the extension library, I hit the following error:

In file included from ..\..\..\generated_cpp_65\com_trolltech_qt_sql\com_trolltech_qt_sql0.cpp:1:
..\..\..\generated_cpp_65\com_trolltech_qt_sql\com_trolltech_qt_sql0.h:23:10: fatal error: qsql.h: No such file or directory
   23 | #include <qsql.h>
      |          ^~~~~~~~
compilation terminated.

I could fix the issue by manually replacing #include <qsql.h> in com_trolltech_qt_sql0.h by #include <QSql>.

If I include the header file qsql.h in my Qt5 application for testing, I see the following warning:

C:\CodingXP\Qt\5.15.2\mingw81_64\include\QtSql/qsql.h:4:4: warning: #warning Header <QtSql/qsql.h> is deprecated. Please include <QtSql/qtsqlglobal.h> instead. [-Wcpp]
    4 | #  warning Header <QtSql/qsql.h> is deprecated. Please include <QtSql/qtsqlglobal.h> instead.
      |    ^~~~~~~

So I think qsql.h is not available in Qt6 anymore.

I still see the file in our version of Qt 6.6.2, but obviously we shouldn't require this file, at least not for Qt 6.
This include is hardcoded in the typesystem_sql.xml, I will fix it.
