The use of "-l" shouldn't override the loading of dumped.elc for
users.  When we need to suppress the use of dumped.elc in the build
process, do so explicitly.

* src/emacs.c (main): Let the loading of dumped.elc override the
loading of a module specified with "-l".
* src/Makefile.in (emacs$(EXEEXT)): Pass --no-loadup when running
temacs.
(bootstrap-emacs$(EXEEXT)): Likewise.

* src/regex.h:
* src/regex.c (re_wctype_parse): Don't use non-ASCII quotes in
comments.

* src/minibuf.c (read_minibuf, read_minibuf_unwind): Save and
restore this-command-keys, to preserve it across recursive-edit.
(Bug#27470)

* lib-src/make-docfile.c (close_emacs_globals): Wrap struct
Lisp_Symbols inside struct.
* src/alloc.c (sweep_symbols): Update use of lispsym.
* src/lisp.h (builtin_lisp_symbol): Likewise.

* nextstep/INSTALL: Correct it, and mention that Emacs can be run
from 'src/emacs'.

* src/nsterm.m (applicationDidFinishLaunching:): When Emacs is
launched outside of a macOS application bundle, change its
activation policy from the default 'prohibited' to 'regular'.

; * etc/NEWS: Mention the change on macOS.

* src/lread.c (read1): Signal an error when a symbol starts with a
non-escaped quote-like character.
* test/src/lread-tests.el (lread-tests--funny-quote-symbols): New
test.
* etc/NEWS: Announce change.

* lisp/cus-start.el: Use the new display-line-numbers group.
* lisp/display-line-numbers.el: New file.

* doc/emacs/custom.texi (Init Rebinding): Re-add entry that used to
belong to linum-mode.
* doc/emacs/modes.texi (Minor Modes): Summarize the mode.
* etc/NEWS: Document display-line-numbers-mode and its customization
variables, and mention that display-line-numbers-width is
buffer-local.

* src/xdisp.c (syms_of_xdisp) <display-line-numbers-width>: Fix a
typo.

* configure.ac: Always set CANNOT_DUMP=yes.
* src/Makefile.in (emacs$(EXEEXT)): Always execute the "dump" code.
(bootstrap-emacs$(EXEEXT)): Always execute the "bootstrap" code.
