wxOSX Retina fixes: wxImageList::GetSize().

wxImageList returns size of its bitmap as pixel size, i.e.  twice the
displayed screen on HiDPI screens.  Unfortunately,
wxImageList::GetSize() is used heavily in (generic) GUI drawing code,
e.g.  to properly size wxListCtrl's icon columns.  As wxImageList is
used primarily by controls, it seems reasonable to adjust for scaling
here, rather than requiring all users of the class to do it.

Remove wx/generic/colrdlgg.h from common GUI headers.

This header is not used in all ports, notably not in wxMSW nor wxGTK.

See #15753.

Use wxScopedArray instead of raw new[]/delete[] and fix memory leak.

Don't leak memory in case of error when reading from the stream in BMP loading
code.

Closes #15789.

Simplify and fix column determination code in wxGridStringTable.

The number of columns in the table is now (since r60717) stored in m_numCols,
so there is no need to get it from wxGrid any more. This is not only simpler
and faster but also more correct as the first row might not have the full
number of values yet.

Closes #15809.

Fix handling of bitmaps with alpha channel in wxMSW wxImageList.

Don't use mask and alpha together, this results in visual artefacts and masks
are unnecessary with RGBA bitmaps anyhow.

The only potentially problematic remaining case is mixing bitmaps with alpha
and mask inside the same image list (as we need to indicate whether we use the
mask or not when creating it), but this should probably be rare and in the
meanwhile we can at least RGBA bitmaps with image lists, which includes doing
this implicitly when they are used as button bitmaps.

Also refactor wxBitmap code to extract part of CopyFromIconOrCursor() to allow
reusing it in the newly added MSWUpdateAlpha().

See #11476.

Reduce the number of realloc() calls in wxHtmlTableCell.

Don't call realloc() after adding each row, this is horribly inefficient, so
preallocate more memory to avoid this.

Closes #15931.

Recompute the tooltip width when changing its text in wxMSW.

This avoids unnecessarily wrapping the tooltips if they are set to a longer
string than their initial value later.

Use settings in wx_vcN_local.props files if they exist.

Allow overriding the default build settings in local properties files for VC11

Fix Unix build using clang with g++ 4.8 headers.

Don't override HAVE_TR1_TYPE_TRAITS detected by configure with
HAVE_TYPE_TRAITS detected by clang __has_include() as the latter is less
reliable and can return true even when the header is not actually usable, as
it happens with g++ 4.8 <type_traits> in non C++11 mode.

Remove code maintaining last item from the treectrl sample.

The code was buggy (e.g. it didn't update the last item correctly after
executing "Append many items" menu command) and seems to be unnecessary.

Remove confusing delete from wxIdRangeManager dtor.

The singleton dtor shouldn't delete the global singleton object, if this were
ever really possible, it would result in an infinite recursion. And even
though it was not (because ms_instance was reset to NULL before destroying the
object pointed by it), this delete was still confusing and unnecessary, so
remove it.

Improve parameter validation in wxStream code.

Replace wxASSERT_MSG()s with wxCHECK_MSG()s to ensure that we don't crash even
if we are passed a NULL pointer, saying "Warning: Null pointer is about to be
used" and crashing just isn't very useful in the grand scheme of things.
