Use a macro to compute the size of arrays at compile time (#18044) 
* 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

PuckBuddy

PuckBuddy

A macropad with a Cirque Glidepoint Trackpad in the middle, powered by the STM32 Blackpill.

Make example for this keyboard (after setting up your build environment):

make mechwild/puckbuddy:default

Flashing example for this keyboard:

make mechwild/puckbuddy:default:flash

Bootloader

Enter the bootloader in 3 ways:

  • Bootmagic reset: Hold down the key at (0,0) in the matrix (assigned to the top left key) and plug in the keyboard while holding it.
  • Physical reset button: Press and hold the boot0 button on the blackpill, tap and release the nrst button on the blackpill, then release the boot0 button.
  • Keycode in layout: Press the key mapped to QK_BOOT if it is available. By default this is the top right key on layer 1.
