f82d6e91bd Revert overenthusiastic procfs fixup
Also, be more systematic in calls to string_to_number.
* src/sysdep.c (list_system_processes) [HAVE_PROCFS]: Allow pids
to be floating-point if they exceed fixnum range.  This partially
reverts my patch 2018-03-09T20:06:05Z!eggert@cs.ucla.edu, which
went too far in fixing string-to-number mishandling.

4ba32858d6 Fix wait_reading_process_output wait_proc hang
* src/process.c (read_process_output): Track bytes read from
a process.
(wait_reading_process_output): If called recursively through
timers and/or process filters via accept-process-output, it is
possible that the output of wait_proc has already been read by
one of those recursive calls, leaving the original call hanging
forever if no further output arrives through that fd and no
timeout has been set.  Fix that by using the process read
accounting to keep track of how many bytes have been read and
use that as a condition to break out of the infinite loop and
return to the caller as well as to calculate the proper return
value (if a wait_proc is given that is).

* src/process.h (struct Lisp_Process): Add nbytes_read to track
bytes read from a process.

3a718ffca0 Finish renaming to internal--daemon-sockname
* doc/lispref/processes.texi (Misc Network): Omit discussion of
internal--daemon-sockname, as non-Emacs code shouldn't rely on it.
* src/process.c (syms_of_process): Rename internal-daemon-sockname
to internal--daemon-sockname.  All uses changed.

d43a724f4e Minor cleanups for server-name fix (Bug#24218)
* lisp/server.el (server--external-socket-initialized): Rename
from server-external-socket-initialised, since it should be
private and Emacs uses American spelling.  All uses changed.
* src/emacs.c, src/lisp.h: Revert previous changes, as the
initialization is now done in src/process.c, which already
includes the relevant files.
* src/process.c (union u_sockaddr): Move decl to top level.
(external_sock_name, Fget_external_sockname): Remove, replacing
with Vinternal__external_sockname.  All uses changed.
(init_process_emacs): Deduce socket name ourselves rather than
have main.c do it.  Use conv_sockaddr_to_lisp instead of doing
it by hand.  Conditionalize it on HAVE_GETSOCKNAME.

(LIBSYSTEMD_LIBS): Edit to empty.
(LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS)
(PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing.
Remove editing of lines that are no longer present in
src/Makefile.in.
* msdos/sed2v2.inp (NEED_MKTIME_INTERNAL)
(NEED_MKTIME_WORKING): Define to 1.
(HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for
DJGPP >= 2.05.

Define PACKAGE_VERSION, not VERSION.
(FLEXIBLE_ARRAY_MEMBER): Define to empty.
(HAVE_DECL_*_UNLOCKED): Define to 0.
(HAVE___BUILTIN_FRAME_ADDRESS): Define to 1.
(PENDING_*): Don't define, as Gnulib no longer supports that.
Instead, define _IOERR as it is in libc/file.h.
* msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to
determine the current directory.
(UPDATE_MANIFEST, UTILITIES): Don't edit.

the command line shorter to fit into 126-char limit of
command.com.
* config.bat: Generate src/deps/*.d files.  Rename more files
like djtar on plain DOS would.
Don't rename src/dir.h: it is long gone.  Edit
lib/gnulib.mk.in using the same scripts as for
lib/Makefile.in.

* src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the
error message.

* src/msdos.h (ENOTSUP): Define to be identical to ENOSYS.

bc511a64f6 Prefer HTTPS to FTP and HTTP in documentation
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November.  Change these FTP URLs to https://ftp.gnu.org
instead.  Make similar changes for URLs to other organizations moving
away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

33be50037c Remove immediate_quit.
The old code that sets and clears immediate_quit was
ineffective except when Emacs is running in terminal mode, and
has problematic race conditions anyway, so remove it.  This
will introduce some hangs when Emacs runs in terminal mode,
and these hangs should be fixed in followup patches.
* src/keyboard.c (immediate_quit): Remove.  All uses removed.

b3a3ed526d Replace QUIT with maybe_quit
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.

543532313a Attempt to fix crashes with threads in GTK builds
* src/xgselect.c (xg_select): Call pselect via thread_select, not
directly, to avoid running Lisp (via unblock_input) when more than
one thread could be running.  (Bug#25247)
* src/process.c (wait_reading_process_output) [HAVE_GLIB]: Call
xg_select directly instead of through thread_select.
* src/xgselect.h (xg_select): Last 2 arguments are no longer
'const', for consistency with thread_select.

fa7d1f075f Fix network streams.
The original code messed up flags in fd_callback_data[], and also
didn't call add_process_read_fd for process-related file descriptors.
