Previously, we used index-ordering for layers, meaning, we looked keys up based
on the index of active layers. This turned out to be confusing, and in many
cases, limiting, since we couldn't easily shift to a lower layer from a higher
one. As such, index-ordering required careful planning of one's layers, and a
deeper understanding of the system.
This patch switches us to activation-ordering: the layer subsystem now keeps
track of the order in which layers are activated, and uses that order to look
keys up, instead of the index of layers. This makes it easier to understand how
the system works, and allows us to shift to lower layers too.
It does require a bit more resources, since we can't just store a bitmap of
active layers, but need 32 bytes to store the order. We still keep the bitmap,
to make `Layer.isActive()` fast: looking up a bit in the bitmap is more
efficient than walking the active layer array, and this function is often used
in cases where speed matters.
As a side effect of the switch, a number of methods were deprecated, and similar
ones with more appropriate names were introduced. See the updated `UPGRADING.md`
document for more details.
Plugins that used the deprecated methods were updated to use the new ones.
Fixes#857.

This change makes Qukeys require a certain minimum amount of time for a
key to be held before it is eligible to get its alternate (i.e. modifier)
value. This should help faster typists avoid unintended modifiers in the
output.

This adds a googletest-based test harness (with googletest pulled into
`testing/googletest`, so we have a fixed state of it), and a few test
cases that demonstrate its use.

Key masking was a bandaid, and we have better ways to achieve the same thing
now. All current users have been switched over to different methods now, so lets
deprecate the masking.
We only put the `DEPRECATED` label on the `maskKey` method, because the rest are
used internally too, and we do not want to emit warnings for those.
Fixes#884.

To make their purpose clearer, rearrange our state: we now have the row-based
array on the top level, instead of every member being an array on its own. The
name of the state variable was changed to `matrix_state_`, to reflect its
purpose. This also allowed us to have its members be named `current`,
`previous`, `debouncer` and `masks`.
All devices using these APIs, and the documentation were updated accordingly.

This drops the now unused `ATMEGA32U4_KEYBOARD`, `ATMEGA32U4_DEVICE_PROPS`,
`ATMEGA_KEYSCANNER_PROPS`, `ATMEGA32U4_DEVICE`, `ATMEGA_KEYSCANNER_PROPS`, and
`ATMEGA_KEYSCANNER_BOILERPLATE` macros.
These were macros that made the code less verbose, but none of them were
future-proof, and all of them were pretty opaque. Using them did not help one to
understand the code.
All use of these have been changed to use the raw structures as-is, which is
more verbose, but much more extensible, and a whole lot clearer in intent
aswell.
Since these are not particularly user facing macros, I opted not to include them
in `UPGRADING.md`, and removed them without prior deprecation.

In order to be able to access the devices as the at-seat user, without having to
fiddle with distro-specific permissions and groups, we need to tag it both
`uaccess` and `seat`, and have the rule sorted before the one that applies
permissions based on these tags. As such, the file had to be renamed as well.

Add a removal date for the removal of the `Key` property direct access, and also
document the deprecation of the HID facade, with the same removal date of the
old APIs.

This has been deprecated in March, 2019, has been a no-op since. While no
removal schedule was posted at the time, I believe it is safe to drop it now.
