Don't change header window foreground colour in wxGenericListCtrl.

As calling wxGenericListCtrl::SetBackgroundColour() doesn't change the header
window background, don't change its foreground in SetForegroundColour()
neither.

Closes #15741.

Check if colour really changed in wxGenericListCtrl::SetBackgroundColour().

Call the base class version to update the colour stored in the base class and
also to avoid changing the colour of the main window unnecessarily if the
colour didn't really change.

This is also consistent with the code in SetForegroundColour() just below.

Use correct cell alignment in generic wxDataViewCtrl mouse handling code.

Don't fall back to wxALIGN_CENTRE, even if the renderer doesn't specify its
own alignment we still have to take the column alignment in consideration, so
use GetEffectiveAlignment() (which had to be made public for this).

This notably fixes (again) hit testing for wxDataViewToggleRenderer in the
generic version.

Closes #15731.

Try to use /proc/self instead of /dev/core in the unit test.

/dev/core doesn't seem to exist on the machines running Travis CI builds,
check if /proc/self can work there.

Don't use native cue banners in wxTextEntry::SetHint() on XP.

The code apparently expected EM_SETCUEBANNER to return false on
pre-Vista systems (where the cue banners don't work).  This isn't the
case in practice, so check for Vista explicitly and use the generic
implementation on XP.

Minor clarifications to wxTextEntry::SetHint() docs.

Update platforms support docs.  Mention event handlers interaction in
the generic implementation.

Work around wrong vsscanf() declaration under HP-UX.

Under this system vsscanf() is declared as taking a non-const char* as first
argument which prevented our code using it from compiling. Wrap it in
wxCRT_VsscanfA() adding the necessary const_cast<> to fix this.

Closes #15638.

Fix crash when Destroy()-ing a TLW with a non-TLW parent.

Generalize the code in wxTopLevelWindowBase dtor checking for the children of
the TLW being destroyed pending for deletion themselves to work when the child
TLW is an indirect child, i.e. was created with a child window of this TLW as
parent and not this TLW itself.
