* Add ARRAY_SIZE and CEILING utility macros
* Apply a coccinelle patch to use ARRAY_SIZE
* fix up some straggling items
* Fix 'make test:secure'
* Enhance ARRAY_SIZE macro to reject acting on pointers
The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.
* explicitly get definition of ARRAY_SIZE
* Convert to ARRAY_SIZE when const is involved
The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
@ rule6a using "empty.iso" @
type T;
const T[] E;
@@
- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```
* New instances of ARRAY_SIZE added since initial spatch run
* Use `ARRAY_SIZE` in docs (found by grep)
* Manually use ARRAY_SIZE
hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers
* Just like char, sizeof(uint8_t) is guaranteed to be 1
This is at least true on any plausible system where qmk is actually used.
Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

* Fix typo for POINTING_DEVICE_GESTURES_SCROLL_ENABLE
Follow the name written in documentation which follows
POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE
* Reword the blurb about POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE in docs

...partially reverts 580bcff4f65a3a9ee301de0fd036de7b610c7ee2 as the
datasheet doesn't claim that the angle tuning as limited to +/- 30
degrees.

* PMW33XX drivers overhaul
This combines the PMW3389 and PM3360 drivers as they only differ in the
firmware blobs and CPI get and set functions. The following changes have
been made:
* PMW3389 now gets the same multi-sensor feature that is already available on the
PMW3360.
* Introduced a shared pmw33xx_report_t struct is now directly readable via SPI
transactions instead of individual byte-sized reads, saving multiple
copies and bitshift operations.
* pmw33(89/60)_get_report functions had unreachable branches in their motion
detection logic these have been simplied as much as possible.
* The fast firmware upload option has been removed as this becomes obsolete by
the newly introduced polled waiting functions for ChibiOS polled waiting
* PMW33(60/89)_SPI_LSBFIRST and PMW33(60/89)_SPI_MODE config options
have been removed as they don't need to be configurable.
* All PMW3389 and PMW3360 defines have been unified to a PMW33XX prefix
to reduce code duplication and make the defines interchangeable
* Adjust keyboards to PMW33XX naming scheme

* Diff reduction between ADNS9800 and PMW3360 drivers.
They are very similar devices. This (somewhat) unreadable diff is
essentially a no-op, but it makes a `vimdiff` between the 2 drivers much
more readable.
* Cleanup pwm3360 driver some more.
Remove redundant calls to spi_start() and spi_stop(), as pmw3360_write()
will already call these.
|

Timing does not match Pixart documentation for this sensor (may have been carried forward from adns9800).
Not aware of any issues coming from this currently.
It should only cause issues when writing to multiple registers in succession which currently only happens during initialization for the PMW3360.
This should prevent future issues with write operations if other features of the sensor are added.
