* internals/internals.texi (Discussion -- Garbage Collection):
Update the part at the top about how to maintain the file with
more tips.
Add a chapter on "window-system support" describing in a general
way how the support for different window systems/device types
works, including the separation between device-independent and
device-dependent parts, device methods, the specific device types
and the "xlike" pseudo-type.

* toolbar-xlike.c (xlike_redraw_frame_toolbars):
* toolbar-xlike.h:
* toolbar-xlike.h (xlike_clear_frame_toolbars):
Rename some files to make them consistent with general naming rules:
xgccache.c -> gccache-x.c
xgccache.h -> gccache-x.h
toolbar-common.c -> toolbar-xlike.c
toolbar-common.h -> toolbar-xlike.h
Fix include-file references. Also change the names of functions
in now-named toolbar-xlike.c to be xlike_foo() instead of common_foo().
Add a longish comment in console-xlike-inc.h describing the "xlike"
system, how it works and what the various files are used for.
