Make it possible to select a rectangular region using the mouse.
The standard binding is C-M-mouse-1.
* lisp/mouse.el (mouse-scroll-subr): Add ADJUST argument.
(mouse-drag-region-rectangle): New.
* lisp/rect.el (rectangle--reset-point-crutches): New.
(rectangle--reset-crutches): Use 'rectangle--reset-point-crutches'.
* src/xdisp.c (remember_mouse_glyph, syms_of_xdisp):
Add 'mouse-fine-grained-tracking'.
* doc/lispref/commands.texi (Motion Events):
Document 'mouse-fine-grained-tracking'.
* doc/emacs/frames.texi (Mouse Commands):
* doc/emacs/killing.texi (Rectangles):
* etc/NEWS: Document rectangular selection with the mouse.
For the ns-KEY-modifier and ns-right-KEY-modifier variables, KEY
being 'control', 'command', 'alternate' and 'function', allow
values on the form (:ordinary SYMBOL :function :SYMBOL :mouse SYMBOL),
so that the key can be used for different modifiers (or none) in
different contexts. This is particularly useful for using the macOS
Option key for extended character entry while still using it as an
Emacs modifier for function keys and mouse clicks.
* src/nsterm.m (mod_of_kind, right_mod, nil_or_none): Helper functions.
(EV_MODIFIERS2): Add KIND argument.
(EV_MODIFIERS): Adapt call to EV_MODIFIERS2.
(ns_get_shifted_character): Use correct event kind for modifiers.
(ns-alternate-modifier, ns-right-alternate-modifier)

(ns-control-modifier, ns-right-control-modifier)
(ns-function-modifier): Rewrite doc strings for new data format.
(QCordinary, QCfunction, QCmouse): Define symbols.
* lisp/cus-start.el: Conform to new data types.
* doc/emacs/macos.texi (Mac / GNUstep Basics)
(Mac / GNUstep Customization): Improved documentation.
* etc/NEWS: Mention the change.
* doc/lispref/display.texi (Displaying Messages): Explain the
behavior of using minibuffer-message if the minibuffer is active.
* src/editfns.c (Fmessage_in_echo_area): New function with body
copied from Fmessage.
(Fmessage): Call minibuffer-message in the active minibuffer,
otherwise call Fmessage_in_echo_area.
(message-in-echo-area): New variable.
* lisp/isearch.el (isearch--momentary-message, isearch-message):
* lisp/minibuffer.el (minibuffer-message, minibuffer-completion-help):
Use 'message-in-echo-area' instead of 'message' where necessary.
* lisp/autorevert.el (auto-revert-handler):
* lisp/man.el (Man-bgproc-sentinel):
* lisp/subr.el (do-after-load-evaluation):
Revert recent changes that replaced 'message' with 'minibuffer-message'.
This is not needed anymore since 'message' uses 'minibuffer-message'
in the active minibuffer.
etags had undefined behavior if input files, lines, tags, etc.,
had more than INT_MAX bytes. Clean up the usage of integer types
to fix the overflow errors I found.
* admin/merge-gnulib (GNULIB_MODULES): Add mempcpy.
* lib-src/etags.c: Include inttypes.h, intprops.h.
(memcpyz): New function. Use it to simplify several occurrences
of memcpy followed by storing a trailing '\0'.
(xnew): Use xnmalloc, to catch overflow on integer multiplication.
(xrnew): Change last arg to multiplier. The type is not needed.
All callers changed.
(node, lineno, charno, linecharno, invalidcharno, make_tag):

(readline):
Use intmax_t for line numbers and character positions, instead of
int or long.
(linebuffer, make_tag, pfnote, total_size_of_entries, put_entry)
(in_word_set, C_symtype, token, cstack, pushclass_above):
(popclass_above, write_classname, consider_token, C_entries)
(Ruby_functions, Makefile_targets, Lua_functions, TeX_commands)
(TeX_decode_env, erlang_func, erlang_attribute, erlang_atom)
(substitute, regex_tag_multiline, nocase_tail, readline_interval)
(readline, savenstr, concat, etags_getcwd, relative_filename)
(linebuffer_setlen):
Use ptrdiff_t for object sizes, instead of int or long or unsigned
or size_t.
(write_classname, C_entries):
Avoid sprintf, as the result could exceed INT_MAX bytes
and then behavior goes haywire.
(main): Use int, instead of unsigned, for argv counts.
(get_language_from_filename): Use bool for boolean.
(Ruby_functions): Prefer strcpy to memcpy when copying "=".
(linebuffer_setlen): Use ‘if’ instead of ‘while’.
(memory_full, xnmalloc, xnrealloc): New functions.
(xmalloc): Use memory_full, and take a ptrdiff_t instead of a size_t.
(xrealloc): Remove; no longer needed.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

(merge_face_ref): Handle the :extend attribute in faces
specified as lists of key/value pairs. (Bug#37774)
mingw.org's MinGW by default targets Windows 9X, so
_WIN32_WINNT is set to a value that bypasses declarations
in system headers we need to compile network_interface_list.
Also, the code needed a workaround for Windows XP, where
some functionality is missing from the GetAdaptersAddresses
API.
* src/w32.c (_WIN32_WINNT): Define to 0x0501, if the value is
lower, temporarily while processing iphlpapi.h.
(address_prefix_match): New helper function.
(network_interface_list): Work around the fact that the
OnLinkPrefixLength member of IP_ADAPTER_UNICAST_ADDRESS is not
available when _WIN32_WINNT < 0x0600. On Windows XP use
special code that calls address_prefix_match to compute the
network prefix length.
* lisp/net/network-stream.el
(network-stream-certificate): Ensure :port is specified as a string to
'auth-source-search' (Bug#38371).
Copyright-paperwork-exempt: yes
Bug#38218
* src/process.c (Fnetwork_interface_list): Extend argument list to
allow requesting full network info and/or IPv4/IPv6 info.
(network_interface_list) [HAVE_GETIFADDRS]: Use getifaddrs to retrieve
interface IP addresses.
* src/process.h: Update prototype of network_interface_list.

* etc/NEWS: Announce IPv4/IPv6 changes in network-interface-list.
* doc/lispref/processes.texi (Misc Network): Document updated arglist
and return values for network-interface-list.
* src/xfaces.c (face_inherited_attr): New function.
(merge_named_face): Call 'face_inherited_attr' when testing
whether a face that inherits from another fits the filtering
criteria specified by ATTR_FILTER.
(merge_face_vectors): Revert the changes made in this function
for filtering by ATTR_FILTER, and remove that argument as
well. These tests are now completely done by the caller, see
'merge_named_face'. (Bug#37774)
If the user cancels the gpg decryption pop-up, auth-source-search
fails *and* epa pops up an error buffer. Fix epa to allow suppressing
that, and ignore errors returned from auth-source-search.
* lisp/epa.el (epa-suppress-error-buffer): New defvar. Bind non-nil
to stop epa popping up an error buffer.
* lisp/net/network-stream.el: require epa when byte-compiling.
(network-stream-certificate): ignore errors when calling
auth-source-search, and suppress the epa error buffer.
* src/xdisp.c (append_space_for_newline): Add an eassert check
that default_face is not null, by calling FACE_FROM_ID instead of
FACE_FROM_ID_OR_NULL. Initialize a local only if needed.
* src/gnutls.c: Move the "#ifdef HAVE_GNUTLS" earlier, so
that "./configure --enable-gcc-warnings --without-gnutls"
does not complain about macros being defined but never used.
Indent "#" directives more consistently.
* lisp/help.el (help-split-fundoc): New arg SECTION to return
only the usage or doc parts of the docstring, or both even if
there is no usage.
* test/lisp/help-tests.el: New file.
* lisp/emacs-lisp/timer.el (debounce, debounce-reduce): New macros.
* lisp/image.el (image-increase-size, image-decrease-size):
Use funcall to call image--change-size-function.
(image--change-size-function): Move code from defun of
image--change-size to defvar that has the value of lambda
returned from debounce-reduce. (Bug#38187)
* lisp/files.el (insert-directory): Always replace "total" with
"total used in directory", even when we don't have free disk space
(bug#13191). This makes the display more consistent.
* doc/emacs/commands.texi (User Input): Add index entry for
the Alt key serving as Meta.
* doc/emacs/custom.texi (Modifier Keys): Add index entries for
Alt, Super, and Hyper modifier keys. (Bug#38315)
* src/xdisp.c (extend_face_to_end_of_line): Make sure the
character position of the stretch glyph inserted to extend the
face is zero, as various other parts of the display code rely
on that. (Bug#38330)
* src/coding.c (get_char_bytes, encode_string_utf_8)
(decode_string_utf_8): Fix commentary.
(encode_string_utf_8): Return the original ASCII string only
if NOCOPY is non-zero.
(decode_string_utf_8): Accept 2 additional arguments STR and
STR_LEN, which allow to pass the input text as a C string.
(make_string_from_utf8): Delegate the job to decode_string_utf_8.
* src/coding.h: Update the prototype of decode_string_utf_8.
* src/json.c (json_encode): Call encode_string_utf_8.
