Add two widget callbacks:
* (make_global): convert widget coordinates from local (relative to
owner) to global (screen).
* (make_local): convert widget coordinates from global (screen) to
local (relative to owner).
Such conversions are required when nested widgets and groups are added to
or removed from another groups.

...to free or not to free the string representation
of vfs_path_t object.
It allows to get rid of string duplication in following cases:
vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = g_strdup (vfs_path_as_str (vpath));
vfs_path_free (vpath);
Now we can write:
vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = vfs_path_free (vpath, FALSE);

How to reproduce:
Run `mcedit .` from an empty shell. mc used to show an error banner. Now
it shows black-on-black error message.
do_refresh() function expects that at least one fullscreen dialog (file
manager, editor, etc) is existing in the dialog stack. If query dialog
is created before any fullscreen one, do_refresh() do nothing.
