Fix problems when dragging frames with the mouse
Re-implement 'mouse-drag-frame' via two new functions -
'mouse-drag-frame-resize' and 'mouse-drag-frame-move'. This is
needed because with some toolkits the notifications for frame
movement and resizing arrive asynchronously, breaking any
calculations using intermediate frame sizes and positions.
* lisp/mouse.el (mouse-drag-mode-line, mouse-drag-left-edge)
(mouse-drag-top-left-corner, mouse-drag-top-edge)
(mouse-drag-top-right-corner, mouse-drag-right-edge)
(mouse-drag-bottom-right-corner, mouse-drag-bottom-edge)
(mouse-drag-bottom-left-corner): Call 'mouse-drag-frame-resize'
instead of 'mouse-drag-frame'.
(mouse-drag-frame): Split into two new functions -
'mouse-drag-frame-move' and 'mouse-drag-frame-resize'.
(mouse-drag-frame-resize, mouse-drag-frame-move): New functions
to implement functionality of the removed 'mouse-drag-frame'.

Fix some problems with moving and resizing child frames
(1) Provide new option 'x-gtk-resize-child-frames' which allows
to either hide a child frame during resizing or asks GTK to
resize it "immediately". This is needed because desktops like
GNOME shell otherwise won't allow resizing child frames at all.
(2) Do not try to synchronize the position of a child frame
after moving it. Needed because the present implementation
introduces a 0.5 secs delay which makes dragging child frames
virtually impossible with Lucid and Motif toolkits on desktops
like GNOME shell that use invisible outer frame borders.

(x-gtk-resize-child-frames): New option that allows to resize
child frames on desktops like GNOME shell (with the mutter WM)
that otherwise refuse to resize them.
* src/xterm.c (x_set_offset): Don't x_sync_with_move for child
frames, it makes moving child frames virtually impossible with
the Lucid and Motif toolkits.
