Fix various warnings which become fatal with later gcc versons in esp-idf 5.x (#1268)

- we cannot use partial initialisation of structs in C++ files (copied from example C files initially it seems)
- IRAM_ATTR uses a COUNTER, do not use the attribute on the implementation
- provide missing copy implementations for Rgb and Hsv
- one no longer can |= on volatile variables; use = | instead
- fix project and header includes
- avoid redefining BLINK_GPIO
- Remove defined but unused variables
- Fix printf formats
- Add missing case statement (HTTP_EVENT_REDIRECT)
- RMT needs to be updated to new interface (CONFIG_RMT_SUPPRESS_DEPRECATE_WARN is on currently; see https://docs.espressif.com/projects/esp-idf/en/release-v5.0/esp32/api-reference/peripherals/rmt.html)
- Adjust tcpip_adpater_* to esp_netif_*
- Use buffered versions of *ntoa* functions for IPv4 addresses and not a static on the stack (also fixes warnings)
- Whatever I missed
