Add support for a pointer to user data. #126

Closed basilfx closed 4 years ago

basilfx commented 4 years ago

This PR adds ucg_GetUserPtr and ucg_SetUserPtr to store user data. This feature is disabled by default, and can be enabled by adding WITH_USER_PTR.

If enabled, the ucg_t structure is extended with an additional void* user_ptr.

This feature is copy/pasted from the U8g2 library (commit). I'm using this for the RIOT-OS port of Ucglib.
