(1) printing_unreadable_object -> printing_unreadable_object_fmt.
(2) printing_unreadable_lcrecord -> printing_unreadable_lisp_object
and fix up so it no longer requires an lcrecord.
These previous changes eliminate most of the remaining places where
the terms `lcrecord' and `lrecord' occurred outside of specialized
code.
(3) Fairly major change: Reduce the number of words in an lcrecord
from 3 to 2. The third word consisted of a uid that duplicated the
lrecord uid, and a single free bit, which was moved into the lrecord
structure. This reduces the size of the `uid' slot from 21 bits to
20 bits. Arguably this isn't enough -- we could easily have more than
1,000,000 or so objects created in a session. The answer is
(a) It doesn't really matter if we overflow the uid field because
it's only used for debugging, to identify an object uniquely
(or pretty much so).
(b) If we cared about it overflowing and wanted to reduce this,
we could make it so that cons, string, float and certain other
frob-block types that never print out the uid simply don't
store a uid in them and don't increment the lrecord_uid_counter.
(4) In conjunction with (3), create new macro NORMAL_LISP_OBJECT_UID()
and use it to abstract out the differences between NEWGC and old-GC
in accessing the `uid' value from a "normal Lisp Object pointer".
(5) In events.c, use zero_nonsized_lisp_object() in place of custom-
written equivalent. In font-mgr.c use external_object_printer()
in place of custom-written equivalents.
