Fix sending of wxEVT_COMMAND_LIST_COL_DRAGGING events in wxMSW wxListCtrl.
We were not getting HDN_TRACK from the system because apparently it is not
sent for header controls with HDS_FULLDRAG style which is used by default by
the native list control. A possible solution would be to forcefully unset this
style but this would make the UI look old fashioned and less intuitive so
instead send these DRAGGING events from HDN_ITEMCHANGING.

Allow to not create wxPaintDC in EVT_PAINT handler in wxMSW.
Failure to create a wxPaintDC in EVT_PAINT handler resulted in many serious
and difficult to debug problems under wxMSW. We used to document that the user
shouldn't do it but this wasn't enough (see #11648). We could also assert if
we detected that a handler didn't create a wxPaintDC but it seems better to
just handle this case gracefully for consistency with the other platforms.
Add wxDidCreatePaintDC global variable which is reset before generating
wxPaintEvent and set to true when ::BeginPaint() is called from wxPaintDC
ctor and validate the update region of the window ourselves if it wasn't set
(meaning that wxPaintDC wasn't created).
Update the documentation to emphasize the link between EVT_PAINT handlers and
wxPaintDC but without saying that wxPaintDC object must always be created in
the handler as this is not true any more.

Don't set stretchable spacers size to 0, this doesn't work so use 1 instead.

Correct test for parent being on screen in wxTLW::DoCentre().
The old test was needlessly complicated, didn't take all cases into account

Correct this by simply checking if the parent rectangle intersects the visible
display area at all.

from the beginning as centering a maximized window on either screen or parent

Add wxIsascii() function and use it instead of isascii() in our code.

Only disable use of non-ANSI functions in strict ANSI mode under Windows.
The changes of r62518 fixed compilation of wx headers in g++ strict ANSI mode
(enabled by th use of -ansi or -std=c++{98,0x} options) with mingw32 but
broke it when using g++ in ANSI mode under Unix. The problems arose at least
due to redeclaration of isascii() with different exception specifier and due
to the lack of wxCRT_StrdupA() definition in the library.
Fix this by simply not disabling the use of non-ANSI functions such as
isascii() and strdup() under Unix as they are still available in the headers
by default because of _GNU_SOURCE predefined by g++.
Notice that if _GNU_SOURCE is explicitly undefined, compilation would probably
still be broken. To fix this we might check whether __USE_SVID is defined
under Linux. Unfortunately doing tests in configure is not an answer as
wxWidgets might not be compiled with the same -std option as the programs
using it, so there is no obviously correct way to fix this.
