editors/emacs: Update to version 27.1

Please refer to the 20200811 UPDATING entry when upgrading
dependent (*-emacs26-*) ports.

Port changes:

- depend on math/gmp
- match upstream by turning CAIRO, HARFBUZZ, and JSON options and on and
  turning MAGICK off by default
- remove OPENMP check for graphics/ImageMagick as the openmp is now
  included in base
- update EMACS_VER in Mk/Uses/emacs.mk
- bump USES=emacs ports or remove BROKEN for net-im/jabber.el and
  deskutils/howm, which now build

+
+  With the release of Emacs version 27.1, the major version of editors/emacs has
+  changed from 26 to 27.  This means the names of some dependent packages have
+  also changed, so simply running `pkg upgrade` will not upgrade foo-emacs26-x
+  to foo-emacs27-x.  To update these packages, run these commands with superuser
+  privileges.
+
+  Binary package users:
+
+    # sh
+    # for i in $(pkg query -g %n '*-emacs26*'); do \
+        nn=$(echo "$i" | sed -e 's/emacs26/emacs27/'); \
+        pkg set -yn "$i":"$nn"; \
+      done;
+    # pkg upgrade
+
+  portmaster users:
+
+    # portmaster -r emacs
