There’s no longer need to have QUIT stand for a slug of C statements.
Use the more-obvious function-call syntax instead.
Also, use true and false when setting immediate_quit.
These changes should not affect the generated machine code.
* src/lisp.h (QUIT): Remove. All uses replaced by maybe_quit.
This improves performance overall on my benchmark on x86-64,
since the interpreted program-counter resides in a machine
register rather than in RAM.
* etc/DEBUG, src/.gdbinit: Remove xbytecode GDB command, as there
is no longer a byte stack to decode.
* src/bytecode.c (struct byte_stack, byte_stack_list)
(relocate_byte_stack): Remove. All uses removed.
(FETCH): Simplify now that pc is now local (typically, in a
register) and no longer needs to be relocated.
(CHECK_RANGE): Remove. All uses now done inline, in a different way.
(BYTE_CODE_QUIT): Remove; now done by op_relative_branch.
(exec_byte_code): Allocate a copy of the function’s bytecode,
so that there is no problem if GC moves it.
* src/lisp.h (struct handler): Remove byte_stack member.
All uses removed.
* src/thread.c (unmark_threads): Remove. All uses removed.
* src/thread.h (struct thread_state): Remove m_byte_stack_list member.
All uses removed. m_stack_bottom is now the first non-Lisp field.

Problem reported by Kylie McClain for musl in:
http://lists.gnu.org/archive/html/emacs-devel/2016-03/msg01592.html
* etc/DEBUG, etc/NEWS: Mention this.
* src/callproc.c (child_setup) [!MSDOS]:
* src/dispnew.c (init_display):
* src/emacs.c (main, Fdaemon_initialized):
* src/minibuf.c (read_minibuf_noninteractive):
* src/regex.c (xmalloc, xrealloc):
Prefer symbolic names like STDERR_FILENO to magic numbers like 2,
to make file-descriptor manipulation easier to follow.
* src/emacs.c (relocate_fd) [!WINDOWSNT]: Remove; no longer needed
now that we make sure stdin, stdout and stderr are open. All uses
removed.
(main): Make sure standard FDs are OK. Prefer symbolic names like
EXIT_FAILURE to magic numbers like 1. Use bool for boolean.
* src/lisp.h (init_standard_fds): New decl.
* src/print.c (WITH_REDIRECT_DEBUGGING_OUTPUT) [GNU_LINUX]:
Remove; no longer needed.
(Fredirect_debugging_output): Define on all platforms, not just
GNU/Linux. Redirect file descriptor, not stream, so that the code
works even if stderr is not an lvalue. Report an error if the
file arg is neither a string nor nil.
(syms_of_print): Always define redirect-debugging-output.
* src/sysdep.c (force_open, init_standard_fds): New functions.
* etc/DEBUG: Add the "Preliminaries" section for GDB beginners.
Most of the content was suggested by Phillip Lord
<phillip.lord@russet.org.uk>. Remove the section about debugging
with the Visual Studio, as building Emacs with the Microsoft
compilers is no longer supported. Minor fixes in some other
sections.
* configure.in (C_OPTIMIZE_SWITCH, CANNOT_DUMP, SYSTEM_MALLOC):
(USE_MMAP_FOR_BUFFERS, C_WARNING_SWITCH): Set with shell, not cpp.
(LIBX): Remove, just use -lX11 in the one place this was used.
(cannot_dump): Replace with CANNOT_DUMP.
* src/Makefile.in (CANNOT_DUMP): Update for configure name change.
* src/s/freebsd.h (USE_MMAP_FOR_BUFFERS):
* src/s/irix6-5.h (USE_MMAP_FOR_BUFFERS):
* src/s/darwin.h (SYSTEM_MALLOC):
* src/s/sol2-10.h (SYSTEM_MALLOC): Move to configure.
* src/m/alpha.h: Remove old comment.
* src/s/aix4-2.h: Update comment.
* src/s/template.h: Remove USE_MMAP_FOR_BUFFERS.
* msdos/sed1v2.inp (CANNOT_DUMP): Update for configure name change.
* admin/CPP-DEFINES: Remove USE_MMAP_FOR_BUFFERS, CANNOT_DUMP.
* etc/DEBUG: Update SYSTEM_MALLOC and CANNOT_DUMP references.
Some re-filling.
