wxGTK30: updated to 3.0.5.1

3.0.5.1

This is a patch release updating the soname of the shared libraries for Unix/ELF \ 
systems which was forgotten in 3.0.5. Because of this, please use the source \ 
archives from this release if you're building wxWidgets shared libraries from \ 
source under these systems, but please refer to 3.0.5 files for all the rest, \ 
i.e. MSW binaries and the documentation.

For completeness, the only other changes compared to 3.0.5 are:
- Workaround for the problem with overflowing maximum command line length in \ 
MinGW builds not using configure.
- Fix for a problem with wxSpinCtrl in wxGTK

3.0.5

All:
- Support nullptr in wxPrintf() and other pseudo-vararg functions.
- Fix problem with wx-config installation and use under NetBSD (wiz).
- Avoid spurious errors on thread creation under NetBSD.

All (GUI):
- Improve stock items consistency and aesthetics (dhowland).
- Implement wxTextCtrl::HitTest() for single line controls.
- Improve wxSVGFileDC to support more of wxDC API (Maarten Bent).

wxMSW:
- Fix handling of AUX2 mouse button events (Trylz).
- Honour alignment flags for multiline buttons using custom colours too.
- Fix crash when using wxCHMHelpController() in 64 bit builds (Xlord2).

wxGTK:
- Fix position of popup menus shown in wxListCtrl.
- Fix not showing wxInfoBar with GTK+ 3 < 3.22.29.
- Potentially incompatible change: wxDataViewModel::Cleared() now works as
  documented cross-platform.  Previously on wxGTK it just emptied the model
  rather than triggering a reload of the model.  If you are working around the
  broken behaviour with wxGTK-specific code in your application you should
  check that your application works correctly with this change.
- Return appropriate values for some previously hard-coded system colours.
