Subject: process_unicode: Fix set_unicode_input_mode()

In the header, this was defined as `set_unicode_input_mode`, but the
implementation had `set_unicode_mode` for a name. Changed the
implementation to match the header.

Subject: 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: 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.

Subject: process_unicode: Replace register_hex32

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.

Subject: 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.

Subject: quantum: Move qk_ucis_state to process_unicode.c

In order to not declare the same variable in multiple objects (which
happens when building UCIS-enabled keymap for both the ErgoDox EZ and
the ErgoDox Infinity), move the declaration to the .c file, and keep
only an extern reference in the header.

Many thanks to @fredizzimo for spotting the error in Travis, and
suggesting the fix.
