Definition of protocols in ESPiLight.cpp conflicts with ESP32 liblwip

[drschlaumeier]

It seems that in ESP32 lib is a new definition of "protocols" which conflicts with the definition in ESPiLight.cpp: "protocols_t *protocols = nullptr;"

liblwip.a(ppp.o)*: (.rodata.protocols+0x0): multiple definition of protocols
ESPiLight.cpp.o*: (.bss.protocols+0x0): first defined here

renaming "protocols" to "protocols_t *esplightprotocols = nullptr;" etc. and changing the rest of code in ESPiLight.cpp resolves the problem.

Thanks for reporting, fixed in c823d77.

Some more fixes to make ESPiLight compile against esp32 are introduced in master. If you have any success or problem with esp32 boards, please report to #23.
