Fix how USB queue overflow is handled in chibios. (#12576)
* Fix how USB queue overflow is handled in chibios.

This commit reverts PR 12472 (commit c823fe2d3f23ed090e36ce39beed4c448298bd2f),
and it implements the original intent of the commit in a better way.
The original intent of the above mentioned commit was to not deadlock the
keyboard when console is enabled, and hid_listen is not started.

The above mentioned commit had a few drawbacks:
1) When a lot of data was printed to the console, the queue would get full,
and drop data, even if hid_listen was running. (For example having matrix debug
enabled just didn't work right at all)
2) I believe the function in which this was implemented is used by all other
USB endpoints, so with the above change, overflow, and data loss could
happen in other important functions of QMK as well.

This commit implements deadlock prevention in a slightly similar way to how
it's done on AVR. There is an additional static local variable, that memorizes
whether the console has timeouted before. If we are in the timeouted=false
state, then we send the character normally with a 5ms timeout. If it does
time out, then hid_listen is likely not running, and future characters should
not be sent with a timeout, but those characters should still be sent if there
is space in the queue. The difference between the AVR implementation and this
one is that the AVR implementation checks the queue state directly, but this
implementation instead attempts to write the character with a zero timeout.
If it fails, then we remain in the timeouted=true state, if it succeeds, then
hid_listen started removing data from the queue, so we can go out of the
timeouted=true state.

* Added comment explaining the timeouted logic to console flow control.

* Console flow control: refactor chibios flowcontrol code to make it more readable, and rename the timeouted variable to timed_out on both chibios and lufa. Changed comments to says timed_out is an approximation of listener_disconnected, to make it clear that it's not the same thing

* fix typo

* resolve race condition between suspend and wake in LUFA

* avoid multiple calls to suspend_power_down() / suspend_wakeup_init()

* Remove duplicate suspend_power_down_kb() call

d4be07dad3 Hid joystick interface (#4226)
* add support for hid gamepad interface
add documentation for HID joystick
Add joystick_task to read analog axes values even when no key is pressed or release. update doc
Update docs/feature_joystick.md
Manage pin setup and read to maintain matrix scan after analog read

* 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

* Fix port addressing for joystick analog read

* The other required set of changes
As per the PR, the changes still holding it up.
Add onekey for testing.
Fix ARM builds.
Fix device descriptor when either axes or buttons is zero.
Add compile-time check for at least one axis or button.
Move definition to try to fix conflict.

* Set verbose back to false

* Add clock divisor, bit order and SPI mode configuration for init

* Add start and stop functions

* Move configuration of mode, endianness and speed to `spi_start()`

* Some breaks here would be good

* Default Adafruit BLE clock divisor to 4 (2MHz on the Feather 32U4)

* Remove mode and divisor enums

Refactor rgblight_reconfig.h (#7773)
* Moved contents of rgblight_reconfig.h to rgblight_post_config.h.

In #3582, rgblight_reconfig.h had to be newly created. Now, the build system of qmk_firmware has a post_cofig feature, so that what was done in rgblight_reconfig.h can now be realized in rgblight_post_config.h.

**This commit does not change the build result.**

Testing script
```shell
  # build on master
  git checkout master
  echo master > /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = no
  make HELIX=verbose helix/rev2:default:clean
  make HELIX=verbose helix/rev2:default
  md5 helix_rev2_default.hex >> /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = yes, with animations
  make HELIX=verbose helix/rev2/back:default:clean
  make HELIX=verbose helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = yes, without animations
  make HELIX=verbose,no_ani helix/rev2/back:default:clean
  make HELIX=verbose,no_ani helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/master_md5.txt

  # build on refactor_rgblight_reconfig.h
  git checkout refactor_rgblight_reconfig.h
  echo refactor_rgblight_reconfig.h > /tmp/branch_md5.txt

  # RGBLIGHT_ENABLE = no
  make HELIX=verbose helix/rev2:default:clean
  make HELIX=verbose helix/rev2:default
  md5 helix_rev2_default.hex >> /tmp/branch_md5.txt

  make HELIX=verbose,no_ani helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/branch_md5.txt

  diff -u /tmp/master_md5.txt /tmp/branch_md5.txt

* Expressions that are too long are difficult to read, so wrap them.

* Edit the expression again

* remove `defined(RGBLIGHT_ANIMATIONS)` in `tmk_core/common/*/suspend.c`, `tmk_core/protocol/*/main.c`

move contents of rgblight_reconfig.h to rgblight.h.

The following changes were made to rgblight.h.

```diff
+#ifdef RGBLIGHT_USE_TIMER
 void rgblight_task(void);

 void rgblight_timer_init(void);
 void rgblight_timer_enable(void);
 void rgblight_timer_disable(void);

+#define rgblight_timer_init()
+#define rgblight_timer_enable()
+#define rgblight_timer_disable()
+#define rgblight_timer_toggle()
+#endif
```

The following changes were made to tmk_core/common/avr/suspend.c, tmk_core/common/chibios/suspend.c, tmk_core/protocol/chibios/main.c, tmk_core/protocol/lufa/lufa.c, tmk_core/protocol/vusb/main.c.

```
```diff
-#if defined(RGBLIGHT_ANIMATIONS) && defined(RGBLIGHT_ENABLE)
+#if defined(RGBLIGHT_ENABLE)
         rgblight_task();
 #endif
```

* remove 'defined(RGBLIGHT_ANIMATIONS)' in tmk_core/common/keyboard.c

fa71c4c91e Fix battery level code in adafruit_ble.cpp (#6648)
* Fix battery level code in adafruit_ble.cpp

The code in tsk_core/protocol/lufa/adafluit_ble.cpp that polls the
battery level for the Adafruit feather BLE controller reads the
regulated voltage, not the raw voltage coming from the battery. To do
that, the Adafruit Feather docs say you should read from pin A9:
https://learn.adafruit.com/adafruit-feather-32u4-basic-proto/power-management#measuring-battery-4-9.
(See also
https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/pinouts#logic-pins-2-9.)

I'm not sure why, but analogRead(9); doesn't read the correct pin.
Checking all available analog pins experimentally, it turns out that
analogRead(7); returns the correct value. So the code above should read:

    state.vbat = analogRead(7);

* Update tmk_core/protocol/lufa/adafruit_ble.cpp
