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.

Recompute the tooltip width when changing its text in wxMSW.

This avoids unnecessarily wrapping the tooltips if they are set to a longer

Set model pointer in wxDataViewEvents generated under wxOSX.

Add missing SetModel() calls.

Use correct column type when adding columns to wxDataViewListCtrl.

Using base class methods such as AppendBitmapColumn() resulted in
wxDataViewListCtrl::AppendColumn() being called but this function always
assumed the column was of "string" variant type -- which was, of course, false
for bitmap columns and so resulted in heap corruption (thanks to the
wonderfully type unsafe code using wxVariant) and a crash.

Get the correct type to use from the column itself now to fix this.

Closes #16008.

Fix crash when using wxThreadSpecificInfo from global object ctor.

When not using compiler TLS support (which is the default now), TLS variable
itself needs to be initialized and user-defined code in the global objects
ctor could be called before this happened, resulting in using uninitialized
CRITICAL_SECTION under Windows and a crash.

Fix this by wrapping global wxThreadSpecificInfo itself in an accessor
function ensuring that it is always initialized before use.

Notice that this required adding wxTLS_TYPE_REF() as wxTLS_TYPE() itself can't
be used for the function return value (__thread or similar can only be used on
the variables).

Closes #16009.

Correct wxDataViewColumn::AppendXXXColumn() return value in case of failure.

Fix fall back to default resolution in wxOSX printing code.

The code was written to use the default resolution if getting it from the
printer failed but only handled failure of PMPrinterGetOutputResolution() and
not of PMSessionGetCurrentPrinter() itself.

Use default resolution if obtaining it failed for any reason (alternative
could be to return error if obtaining it failed for any return...).

No real changes, just use smart pointers in GIF decoding code.

Fix memory leak on error return from wxMsgCatalogFile::FillHash().

Use wxScopedPtr to make memory management simpler and to ensure that all

returned false earlier due to the MO file being invalid.
