Allow one-shot modifiers to be chained

Many a times one would want to use multiple modifiers with the same key,
preferably without having to hold anything, like `Ctrl+Shift+C` or
`Ctrl+Shift+V` to copy/paste in GNOME Terminal. To make this possible, we need
to be able to chain one-shot modifiers, so that we can have multiple of them
active at the same time.

The easiest way to accomplish this is that whenever we activate a one-shot
modifier, we apply it on top of the existing set, instead of re-setting the
state. When deactivating, either due to an interrupt, or due to a timeout, we
deactivate all oneshots anyway, so the clearing part is covered. When we turn
the one-shot modifier into a toggle, that will also clear all one-shot modifiers
first, so we covered that case too.

Fixes qmk#2796, qmk#1580, and qmk#856.

Xton has a dz60 (qmk#2952)

* FORK!

* WIP - just how i like it

* empty

* more movement

* mouse keys

* more vimminess

* append/insert shift

* WIP - vim macros

* blocked out layer below in cmd mode.

also, about to restart my cmd approach.

* WIP - new vim layer

ripoff of the ergodox one, but rewritten as a state machine.

* debugged some, got key repeat working

* moooar coverage

* moooar coverage

* regular vis mode

* basically done with basics.

* some refactoring

- common movement sequences into helper function
- added some rgb controls

* modkey passthru feature

* stdized on cmd-left/right instead of ctrl-a/e

sadly. as there's no reliable shift-ctrl-e

* indicator lights

* moved vim layer into userspace

* cleaned up some yanking edge cases

* docs and some tweaks to layerescapes

* updated/added license strings

* updated comments

* moved config changes to keymap

* spurious changes removed

* cleanup pass, HT drashna for suggestions

- used _keymap() pattern to better modularize event processing in userspace
- made some static things static
- removed unused function
- improved reset.

* dz60 started. keymaps done.

* bugfixes: missing state change in d-, lspace should toggle vim mode.

* Caps lock indicator -> vim indicator.

And adjusted mousekey settings.

* don't actually need the second move trigger and it makes typing less responsive.

* some oppurtunistic bugfixing from my other keyboard (sorry)

* added readme for my dz60 keymap.

* bugfixing and comments updated (niu_mini)

* cleanup as suggested from review

Added bootmagic_lite() (qmk#2942)

Move ckeys workshop to its own directory (qmk#2928)

* move obelus and nakey to ckeys directory

* delete the originals

* short readme about ckeys

* edit readmes to reflect new changes

* add build guide info..and here's me trying to retrigger the build job

General RGB matrix fixes (qmk#2931)

* Added Modular keyboards L,R and NUM

Created code modules for the 3 modules of the modular keyboard.
Original idea by MechboardsUK. Uses i2c implementation similar to lets
split

* Remove modular from master

This is to fix incorrect branching

* General fixes for RGB_matrix

- Complited speed support for all effects
- Fixed raindrop effects to initialized after toggle
- Fixed raindrop effects to use all available LEDs
- Fixed effect step reverse function
- Moved RGB_MATRIX_SOLID_REACTIVE under correct flag

* Documentation update for RGBmatrix

* More doc updates

gcc 8.10 compilation fix (qmk#2914)

* Use memmove instead of memcpy

gcc 8.1 gives the following error:
lib/lufa/LUFA/Drivers/USB/Class/Common/HIDParser.c:93:5: error: 'memcpy' accessing 42 bytes at offsets 28 and 0 overlaps 14 bytes at offset 28 [-Werror=restrict]

This patch resolve this by using memmove instead
