Subject: [PATCH 1/8] process_unicode: Small refactor & linux fix

This moves the unicode input start / end sequences into their own
functions, so keymaps and other functionality can build on it too.

At the same time, it changes how the Linux variant works, to match
reality: CTRL+SHIFT must be unregistered too, and we close the thing
with a Space instead.

Subject: [PATCH 2/8] process_unicode: Add a way to enter unicode symbols by
 name

The purpose of this change is to allow keymaps to specify a dictionary
of unicode symbol name to code mappings, and let the person at the
keyboard enter unicode symbols by name.

This is done by having a way to trigger unicode symbol input mode, when
all keys are cached until Esc, Enter or Space are pressed. Once that
happens, we try to look up the symbol from our lookup table. If found,
we erase back, and type the unicode magic in to get that symbol. If not
found, we still erase back, start unicode input mode, and replay what
the user typed in.

It turns out that register_hex32 did not work reliably, and some systems
only allow 7 chars after the unicode magic sequence, while others allow
8. To remedy the situation, store the codes as strings, and type those
in instead of doing bit shifting magic.

From e8845f0daf8dc7a7674dc5420cc5a684bbbea09b Mon Sep 17 00:00:00 2001
From: Gergely Nagy <algernon@madhouse-project.org>
Date: Mon, 15 Aug 2016 10:07:13 +0200
Subject: [PATCH 8/8] process_unicode: Introduce a slight delay

When entering unicode codes, use some delay, so the OS has time to
process the information. This is not needed on all systems, but some
seem to require it.
