Subject: [PATCH] api: fixed mis-aligned the ref count size, u8 -> u16

C++ API Modifications:
* uint8_t Paint::unref() -> uint16_t Paint::ref()
* uint8_t Paint::ref() -> uint16_t Paint::unref()
* uint8_t Paint::refCnt() -> uint16_t Paint::refCnt()

C API Modifications:
* uint8_t tvg_paint_ref(...) -> uint16_t tvg_paint_ref(...)
* uint8_t tvg_paint_unref(...) -> uint16_t tvg_paint_unref(...)
* uint8_t tvg_paint_get_ref(...) -> uint16_t tvg_paint_get_ref(...)
