(1) Make lrecord UID's have a separate UID space for each object.
Otherwise, with 20-bit UID's, we rapidly wrap around, especially
when common objects like conses and strings increment the UID value
for every object created. (Originally I tried making two UID spaces,
one for objects that always print readably and hence don't display
the UID, and one for other objects. But certain objects like markers
for which a UID is displayed are still generated rapidly enough that
UID overflow is a serious issue.) This also has the advantage of
making UID values smaller, hence easier to remember -- their main
purpose is to make it easier to keep track of different objects of
the same type when debugging code. Make sure we dump lrecord UID's
so that we don't have problems with pdumped and non-dumped objects
having the same UID.
(2) Display UID's consistently whenever an object (a) doesn't
consistently print readably (objects like cons and string, which
always print readably, can't display a UID), and (b) doesn't
otherwise have a unique property that makes objects of a
particular type distinguishable. (E.g. buffers didn't and still
don't print an ID, but the buffer name uniquely identifies the
buffer.) Some types, such as event, extent, compiled-function,
didn't always (or didn't ever) display an ID; others (such as
marker, extent, lstream, opaque, opaque-ptr, any object using
internal_object_printer()) used to display the actual machine
pointer instead.
(3) Rename NORMAL_LISP_OBJECT_UID to LISP_OBJECT_UID; make it work
over all Lisp objects and take a Lisp object, not a struct pointer.
(4) Some misc cleanups in alloc.c, elhash.c.
(5) Change code in events.c that "deinitializes" an event so that
it doesn't increment the event UID counter in the process. Also
use deadbeef_memory() to overwrite memory instead of doing the same
with custom code. In the process, make deadbeef_memory() in
alloc.c always available, and delete extraneous copy in mc-alloc.c.
Also capitalize all uses of 0xDEADBEEF. Similarly in elhash.c
call deadbeef_memory().
(6) Resurrect "debug SOE" code in extents.c. Make it conditional
on DEBUG_XEMACS and on a `debug-soe' variable, rather than on
SOE_DEBUG. Make it output to stderr, not stdout.
(7) Delete some custom print methods that were identical to
external_object_printer().
