* etc/NEWS: Move entry since it's an incompatible change.
* lisp/emacs-lisp/shortdoc.el (vector): Make the example relevant.
* lisp/subr.el (copy-tree): Rename second argument,
since 'vector-like' is a term with a specific meaning in Emacs
but not the one intended here.
* doc/lispref/lists.texi (Building Lists): Rename second argument,
and make it clear that the input must be acyclic.
* doc/lispref/records.texi (Record Functions):
Be more precise: `copy-sequence` is used to copy records,
`copy-tree` copies trees made of records etc.
* test/lisp/subr-tests.el (subr--copy-tree): Extend and strengthen the
test considerably, using the print-circle trick to detect structure
sharing precisely.
* doc/lispref/lists.texi (Building Cons Cells and Lists): Document
new behavior of 'copy-tree'.
* doc/lispref/records.texi (Record Functions): Cross-reference to
lists.texi.
* etc/NEWS: Mention change. (Bug#63509)
* lisp/emacs-lisp/shortdoc.el: Add 'copy-tree' example to vector
group.
* lisp/subr.el (copy-tree): Recurse into records as well as
vectors when optional second argument is non-nil. Rename second
argument from VECP to VECTOR-LIKE-P.
* test/lisp/subr-tests.el: Test new behavior.
* doc/lispref/Makefile.in (srcs): Add the forgotten records.texi.
* doc/lispref/records.texi (Records): Recommend that record type
names use package-naming conventions.
* etc/NEWS: Add the naming convention recommendation for record
types.
Since copy-sequence seems to be needed anyway for records, have it
work on records, and remove copy-record as being superfluous.
* doc/lispref/records.texi (Records, Record Functions):
* lisp/emacs-lisp/cl-macs.el (cl-defstruct):
* lisp/emacs-lisp/eieio.el (make-instance, clone):
* test/src/alloc-tests.el (record-3):
Use copy-sequence, not copy-record, to copy records.
* doc/lispref/sequences.texi (Sequence Functions)
(Array Functions): Document that aref and copy-sequence
work on records.
* etc/NEWS: Omit copy-record.
* src/alloc.c (Fcopy_record): Remove.
* src/data.c (Faref): Document that arg can be a record.

* objects.texi (Record Type): improve description of what
`type-of' returns for records.
(Type Descriptors): new section.
* elisp.texi: reference it.
* records.texi (Records): reference it. Document behaviour when type
slot is a record.
* alloc.c (Fmake_record, Frecord): mention type desciptors.
* doc/lispref/records.texi (Records): Mention size limit.
* etc/NEWS: Mention records.
* src/alloc.c (allocate_pseudovector, allocate_record):
Prefer 'PSEUDOVECTOR_SIZE_MASK' to its definiens.
(allocate_record): Check arg range here, not in callers, as this
simplifies the code. Use allocate_vectorlike instead of
allocate_vector, to avoid duplicate runtime tests.
(Fmake_record, record): Don't mention PSEUDOVECTOR_SIZE_BITS in
the doc string, as it is not visible to the user.
(Fmake_record, record, Fcopy_record):
Prefer make_lisp_ptr to XSETVECTOR.
(record): Broaden memcpy to copy the type, too.
* lisp/emacs-lisp/cl-lib.el (cl--old-struct-type-of): New function.
(cl-old-struct-compat-mode): New minor mode.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): Pass `record' to
cl-struct-define to signal use of record objects.

cl-struct-define): Enable legacy defstruct compatibility.

old-struct): New tests.

(cl--generic-struct-specializers): Adjust to new tag.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): When type is nil, use records.
Use the type symbol as the tag. Use copy-record to copy structs.

code to new format.
