Score flex-style completions according to match tightness

The new completion style needs to score completion matches so that we
can use it later on when sorting the completions.  This is because, in
the flex style, "foo" can now match "foobar", "frodo" and
"barfromsober" but we probably want "foobar" to appear at the top of
the completion list.

This change makes the new flex completion style add sort-order hints
under the completion string's `completion-style-sort-order' property.

* lisp/minibuffer.el (completion-pcm--hilit-commonality): Propertize
completion with 'completion-pcm-commonality-score.
(completion-flx-all-completions): Propertize completion with
completion-style-sort-order and completion-style-annotation.

Add a new 'flex' completion style

* lisp/minibuffer.el (completion-styles-alist): Add flex.
(completion-substring--all-completions): Accept
transform-pattern-fn arg.
(completion-flex-all-completions, completion-flex-try-completion)
(completion-flex--make-flex-pattern): New functions.

* admin/notes/hydra: Small updates.

Add missing categories L, R, . and SPC to rx

* lisp/emacs-lisp/rx.el (rx-categories):
Add missing categories L, R, . and SPC.  (Bug#34436)

Simplify url-digest-auth-make-cnonce

* lisp/url/url-auth.el (url-digest-auth-make-cnonce):
Simplify by using encode-time instead of round-tripping
through a format-time-string and ‘read’.

Don’t assume CURRENT_TIME_LIST

Use timestamp accessors instead of delving into a timestamp
format that is planned to change in a future version.

Use time-less-p instead of delving into timestamp format.
* lisp/ido.el (ido-wash-history, ido-file-name-all-completions):
Use time-equal-p instead of delving into timestamp format.
* lisp/net/tramp-adb.el (tramp-adb-handle-set-file-times):
Use format-time-string to generate POSIX ‘test -t’ format instead
of timestamp-format-dependent code along with shell arithmetic
that can’t possibly do the right thing on a POSIX platform.

Simplify use of encode-time

Most uses of (apply #'encode-time foo) can now be replaced
with (encode-time foo).  Make similar simplifications.

Properly remove stale Flymake diagnostics on :region reports

Make window choice in xref commands configurable

Previously, it wasn't easy to tell xref.el commands like
xref-find-definitions or xref-find-definitions-other-window how to
choose a window for the *xref* buffer or how to find windows for
displaying the results after choosing a candidate.  This patch makes
that task easier, but keeps the current behaviour intact.

Co-authored-by: João Távora <joaotavora@gmail.com>

This incorporates:
2019-02-02 dtoastr, ftoastr, ldtoastr: port to c-strtod changes
2019-02-01 c-strtod, c-strtold: use the bug fixes
2019-01-30 strtold: New module
* doc/misc/texinfo.tex, lib/ftoastr.c, lib/regexec.c, lib/stdlib.in.h:
* m4/stdlib_h.m4:
Copy from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* m4/c-strtod.m4: Remove.

Fix unlikely user-full-name integer overflow

* src/editfns.c (Fuser_full_name):
Don’t assume uid fits into fixnum.

Prevent segfault in bootstrap-emacs on MinGW

* src/emacs.c (main) [WINDOWSNT]: Fix logic of determining by
argv[0] whether to use the static heap.  (Bug#34277)

Fix Bug#34221

* lisp/progmodes/project.el (project--files-in-directory):
Support remote files.  (Bug#34221)

Fix window splitting behavior of 'display-buffer-at-bottom'

* lisp/window.el (display-buffer-at-bottom): Never split an
arbitrary bottom window.  Try to split the frame's main
window instead (Bug#33870).

Fix bugs caused by running window change functions during redisplay

* src/xdisp.c (redisplay_internal): Run window change
functions before updating the display so changes induced by
these functions can get caught by redisplay (Bug#34138).
* src/window.c (run_window_change_functions): Bind
Qinhibit_redisplay to avoid that the minibuffer window gets
resized while running window change functions (Bug#34179,

* etc/PROBLEMS: Mention profiler-report bug (Bug#34235).

* make-dist: Avoid "Bad fd number" error with dash.

* make-dist: Remove references to src/stamp-h.in.

This file was removed two years ago in 2f89350.

* make-dist: Fix --no-update with no pre-existing MANIFEST.

Restore SETFATTR substitution

* configure.ac (SETFATTR): Restore the AC_SUBST of this
that was inadvertently removed when pdumper support was added.
Need for ./configure --with-dumping=unexec on Fedora 29.

Make make-dist more automatic

Simplify make-dist maintenance by having it generate its
list of files more automatically.  Put the list of distributed
files into a file MANIFEST that can be used in the unusual
situations when you’re making a distribution without having
access to a Git repository.
* make-dist (top_level_ChangeLog): Now nonempty if the
distribution tarball will contain a ChangeLog, instead of
being nonempty when a ChangeLog is requested, Git is present
and a readable ChangeLog exists.  The new interpretation makes
the script a bit easier to follow.
(possibly_non_vc_files, info_files, mkdir_verbose)
(file_to_skip, MANIFEST_subdir_sed, tempsubdirs):
New variables.
(MANIFEST): Update and use this file, which now records what
files are distributed.

Rename CANNOT_DUMP to HAVE_UNEXEC

* configure.ac (CANNOT_DUMP): Remove.  All uses removed,
or changed to the negative of with_unexec.
(HAVE_UNEXEC): New macro.  All uses of CANNOT_DUMP changed
to the negative of this macro.

Omit some linker hacks if not doing unexec

* configure.ac (LDFLAGS, LD_SWITCH_SYSTEM_TEMACS):
Omit some funky linker flags if not supporting unexec.

Use macOS linker hacks only if needed
* configure.ac: On darwin, link with -fno-pie and -headerpad
only if configuring with unexec.

Stop using macOS -prebind option

* configure.ac (LD_SWITCH_SYSTEM_TEMACS): Remove -prebind,
which has been obsolete and ineffective since Mac OS X 10.4 (2005),
which was never necessary for correct operation, and which now
generates annoying warnings.  Problem reported by Robert Pluim in:

Prefer static to extern where either will do

* src/charset.c (charset_table_size):
* src/pdumper.c (dump_private):
* src/sysdep.c (init_sigsegv):
* src/window.c (old_selected_window):
Now static.
* src/charset.c (charset_table_size):
Now int, since the value always fits in int.
* src/gtkutil.c (xg_gtk_initialized): Now present only if
HAVE_XWIDGETS, to make it clearer that this is an xwidgets
hack.  All uses changed.
* src/lread.c (ndefsubr): Remove; unused.
* src/pdumper.h: Use usual GNU indenting style for functions,
since my static-vs-extern checking hack relies on it.

(pdumper_handle_page_fault): Remove unused decl.

Widen modiff counts to avoid wraparound

Widen modification counts to at least 64 bits, to make
wraparound practically impossible.
* doc/lispref/buffers.texi (Buffer Modification):
Don’t say the modification-count can wrap around.
* src/buffer.c (Frestore_buffer_modified_p, Fbuffer_swap_text)
(modify_overlay):
* src/insdel.c (insert_1_both, insert_from_string_1)
(insert_from_gap, insert_from_buffer_1)
(adjust_after_replace, replace_range, replace_range_2)
(del_range_2, modify_text):
* src/textprop.c (modify_text_properties):
Use modiff_incr instead of incrementing directly.
(Fbuffer_modified_tick, Fbuffer_chars_modified_tick):
Don’t assume modification counts fit into fixnums.
* src/buffer.h (struct buffer_text, struct buffer):
* src/cmds.c (internal_self_insert):
* src/fileio.c (Finsert_file_contents):
* src/indent.c (last_known_column_modified):
* src/keyboard.c (command_loop_1):
* src/marker.c (cached_modiff):
* src/syntax.c (find_start_modiff, parse_sexp_propertize)
(find_defun_start):
* src/window.h (struct window):
Use modiff_count for modification counts.
* src/editfns.c (Fsubst_char_in_region):
Copy instead of incrementing modification counts,
since integer overflow checking is not needed here.

(modiff_incr, modiff_to_integer): New inline functions.
* src/pdumper.c (dump_buffer): Update hash.
