* Merge point for 2020 Nov 28 Breaking Change

* Add brightness level API to OLED driver

* Set default brightness to 255

* 3731 bug fix

* bug fixes

* Fix dirtying in oled_write_pixel()

Set the dirty bit for the block only if oled_write_pixel() actually
changed the buffer state.  Without this check oled_write_pixel() could
not be used inside the oled_task_user() code using the “redraw always”
style, because the blocks touched by oled_write_pixel() would always
appear dirty, and oled_render() would not proceed beyond the first such
dirty block.

* Fix oled_write_pixel() with 90/270 degree rotation

Use oled_rotation_width instead of OLED_DISPLAY_WIDTH, so that a rotated
display would be handled correctly.

* Fix compilation with custom OLED_BLOCK_COUNT and OLED_BLOCK_SIZE

Some OLED sizes (e.g., 64×48) may require a nonstandard value of
OLED_BLOCK_COUNT.  The documentation says that this value may be
redefined in config.h, but actually trying to redefine it caused a
compile error, because the macro was redefined in oled_driver.c.
Make the OLED_BLOCK_COUNT definition in oled_driver.c respect any
user override, and do the same for OLED_BLOCK_SIZE just in case.

* Fix handling of out-of-range bits in oled_dirty

If a custom OLED_BLOCK_COUNT value is specified, some bits in oled_dirty
may not correspond to existing blocks; however, if those bits are set
somewhere (e.g., by code with sets oled_dirty to ~0 or even -1),
oled_render() would try to handle them and could access memory beyond
oled_buffer and perform hardware operations with out of range values.
Prevent this by masking off unused bits in oled_render(), and also avoid
setting those bits in other functions.

* Fix potentially wrong dirtying in oled_write_char()

oled_write_char() tried to mark the position just beyond the written
character as dirty; use (OLED_FONT_WIDTH - 1) to dirty the last position
still belonging to the character instead.

* Fix `#define OLED_BLOCK_TYPE uint32_t` on AVR

Using uint32_t as OLED_BLOCK_TYPE did not work properly on AVR, because
some bit shifts were performed using 16-bit int.  Add explicit casts to
OLED_BLOCK_TYPE to those shifts.

* Fix issue with data transfer of CS1_SW7 to CS18_SW7.

* Fix issue with handling of scaling register buffer's dirty flag.

* Remove unused extern declaration.

* Compaction of struct is31_led utilizing bit fields.

Some STM32 chips have STM32_DMA1_STREAM1 as the first DMA stream, others
(F4xx, F7xx, H7xx) have STM32_DMA1_STREAM0.  Instead of those names, use
STM32_DMA_STREAM(0), which should always give the first stm32_dma_stream_t
structure in the DMA streams array, so that the stream ID would be
calculated correctly.

* Incorporates patches and changes to HID reporting

There are some patches provided by @a-chol incorporated on this commit,
and also some changes I made to the HID Report structure.

The most interesting is the one dealing with number of buttons: Linux
doesn't seem to care, but Windows requires the HID structure to be byte
aligned (that's in the spec). So if one declares 8/16/32... buttons they
should not have any issues, but this is what happens when you have 9
buttons:

```
 bits |0|1|2|3|4|5|6|7|
      |*|*|*|*|*|*|*|*| axis 0 (report size 8)
      |*|*|*|*|*|*|*|*| ...
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*| axis 6
      |*|*|*|*|*|*|*|*| first 8 buttons (report size 1)
      |*| | | | | | | | last of 9 buttons, not aligned
```

So for that I added a conditonal that will add a number of reports with
size 1 to make sure it aligns to the next multiple of 8. Those reports
send dummy inputs that don't do anything aside from aligning the data.

Tested on Linux, Windows 10 and Street Fighter (where the joystick is
recognized as direct-input)

* Add save and restore of each pin used in reading joystick (AVR).
Allow output pin to be JS_VIRTUAL_AXIS if the axis is connected to Vcc
instead of an output pin from the MCU.

Fix joystick report id

Fix broken v-usb hid joystick interface. Make it more resilient to unusual settings (none multiple of eight button count, 0 buttons or 0 axes)

Correct adc reading for multiple axes. Piecewise range conversion for uncentered raw value range. Input, output and ground pin configuration per axis.

Documentation fixes
