* lisp/term.el (term-mode): Use window-screen-lines to set the initial
  window height.

* src/image.c (image_set_crop) [HAVE_NATIVE_TRANSFORMS]: Don't call
compute_image_size, as it is already called from image_set_size.
(image_set_size, image_set_crop) [HAVE_NATIVE_TRANSFORMS]: Use harmless
matrix transformation code also for USE_CAIRO and HAVE_NTGUI cases,
though image_set_transform is not yet implemented on them.

* nt/mingw-cfg.site (gl_cv_func_copy_file_range): Set to "yes",
to avoid compiling lib/copy-file-range.c on MS-Windows.

* src/image.c (image_set_crop) [!HAVE_NATIVE_TRANSFORMS]:
Don’t call compute_image_size, as it does not exist and its
result is not needed.

The copy_file_range syscall (introduced in Linux kernel
version 4.5) can copy files more efficiently via server-side
copy etc.
* admin/merge-gnulib (GNULIB_MODULES): Add copy-file-range.
* lib/copy-file-range.c, m4/copy-file-range.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (Fcopy_file): Try copy_file_range first,
falling back on read+write only if copy_file_range failed or
if the input is empty and so could be a /proc file.

This incorporates:
2019-06-04 copy-file-range: new module

double-to-int conversion and to reduce bignum rotations correctly.
(image_set_crop): Finish up previous correction, by not re-setting
width and height if compute_image_size has set them.
Prefer shifting right by 1 to dividing by 2 if either will do.

* src/xdisp.c (init_to_row_end): Fail if the first visible
position on the line following ROW is bidi-reordered and could
be composed.  (Bug#35811)

USE_CARIO needs these.

Since the hostname returned by irc.freenode.net can be something other
than irc.freenode.net, e.g. niven.freenode.net, the entries for
rcirc-authinfo and rcirc-server-alist will not match.
* lisp/net/rcirc.el (rcirc-handler-001): Check rcirc-server (the
hostname connected to) instead of rcirc-server-name (the hostname
returned), this corresponds with what rcirc-authenticate does.
Moreover, if rcirc-auto-authenticate-flag is set, check the
corresponding rcirc-authinfo, regardless of whether the
rcirc-authenticate-before-join must happen.

Copyright-paperwork-exempt: yes

Instead of using after-change-functions.  Also, stop consulting
nxml-prolog-regions during syntax-propertize.  It turns out the
problems fixed by using prolog information are actually due to using
the wrong syntax table during propertizing.  This was fixed in
2019-06-04 "* lisp/emacs-lisp/syntax.el: Use syntax-ppss-table for
syntax-propertize." so consulting the prolog data is no longer needed.
* lisp/nxml/nxml-rap.el (nxml-maybe-rescan-prolog): Remove.
* lisp/nxml/nxml-mode.el (nxml-mode): Stop using it.
