more mc-alloc-related factoring; make it hard to do the wrong thing
postgresql/postgresql.c, postgresql/postgresql.h: MC-Alloc refactoring.
ldap/eldap.c, ldap/eldap.h: MC-Alloc refactoring.
alloc.c, buffer.c, console.c, emacs.c, file-coding.c, lrecord.h, lstream.c, mule-charset.c, print.c, scrollbar-gtk.c, scrollbar-msw.c, scrollbar-x.c, scrollbar.c, symbols.c, symeval.h, unicode.c, window.c, xemacs.def.in.in: rename `struct lcrecord_header' to `struct old_lcrecord_header';
likewise for `old_basic_alloc_lcrecord', `old_free_lcrecord',
`old_zero_lcrecord', `old_zero_sized_lcrecord', `old_copy_lcrecord',
`old_copy_sized_lcrecord', `old_alloc_lcrecord_type'. Created new
LISPOBJ_STORAGE_SIZE() used only on objects created through allocation
of Lisp-Object memory instead of basic xmalloc()/xfree(). This is
distinguished from malloced_storage_size(), for non-Lisp-Objects.
The definition of LISPOBJ_STORAGE_SIZE() can reduce down to
malloced_storage_size() when not MC-ALLOC, but with MC-ALLOC it's
a different function.
The whole point other than cleaning up the use of LISPOBJ_STORAGE_SIZE
is to make it harder to accidentally use the old kind (lowercase) of
function in new code, since you get a compile error.
