* src/lread.c (grow_read_buffer): New function, which uses xpalloc.

This doesn’t fix any bugs, but simplifies the code a bit.
Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

A few Emacs diagnostics go directly to stderr, and so can't easily
contain curved quotes (as non-UTF-8 locales might mishandle them).
Instead of bothering to add support for this rarity, reword the
diagnostics so that they don't use grave accent to quote.

Reword stderr diagnostics to avoid quoting `like this'.
* src/unexmacosx.c: Include errno.h.
* src/xfns.c (select_visual): Encode value for locale.

* make-docfile.c: Revamp to generate table of symbols, too.
Include <stdbool.h>.
(xstrdup): New function.
(main): Don't process the same file twice.
(SYMBOL): New constant in enum global_type.

for int or v.svalue for string. All uses changed.
(add_global): New arg svalue, which overrides value, so that globals
can have a string value.
(close_emacs_global): New arg num_symbols; all uses changed.
Output lispsym decl.
(write_globals): Output symbol globals too. Output more
ATTRIBUTE_CONST, now that Qnil etc. are C constants.
Output defsym_name table.
(scan_c_file): Move most of guts into ...

record symbols found. Don't read past EOF if file doesn't
end in newline.

Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.

DEFSYM Qdeactivate_mark before the corresponding var.

New macros.
