Improvements for debugging GPIO conflicts. HTML UI integration still pending.
* pinManager can be asked for pin owner (String) and pin special purpose (string).
* wled.cpp: show GPIO allocation when compiling with WLED_DEBUG
* pinmanager: show Pin Owner as name when possible.
The results looks like this
GPIO | Assigned to | Info
--------|-----------------------|------------
i/o 0 Button
i/o 1 debug Serial TX
i/o 2 DMX out
i/o 3 ./. Serial RX
i/o 5 ./. SPI SS
i/o 15 AudioReactive (UM)
i/o 16 LEDs (digital)
i/o 17 Relay
i/o 18 ./. SPI CLK
i/o 19 IR Receiver SPI MISO
i/o 21 I2C I2C SDA
i/o 22 I2C I2C SCL
i/o 23 ./. SPI MOSI
i/o 32 AudioReactive (UM)
* Improved pin manager, ethernet config
* Ethernet is configured prior even to LED pins
* Pin Manager allocation / deallocation functions
now take an "ownership" tag parameter, helping
avoid accidentally free'ing pins that were allocated
by other code
* Pin Manager now has ability to allocate multiple
pins at once; Simplifies error handling
* Fix operator precedence error
Bitwise AND has lower precedence than the
relational "greater than" operator.
* PinManager update for some user modules
* don't build everything...
* Final step to reduce RAM overhead
* update comment
* remove macros
* Remove leftover allocated
* Init ethernet after settings saved
