[Bug]: 1.8.0 has breaking undocumented API change

[dvershinin]

What happened?

I tried to compile Tengine with xquic 1.8.0 and surely it failed

Steps To Reproduce

Compile Tengine with xquic 1.8.0. It choked on few arguments passed to xqc_scid_str.
Even without checking with Tengine code, we can see that documentation here has:

unsigned char *xqc_scid_str(const xqc_cid_t *scid);

While the code for xquic 1.8.0 here:

unsigned char *
xqc_scid_str(xqc_engine_t *engine, const xqc_cid_t *scid)
{
    xqc_hex_dump(engine->scid_buf, scid->cid_buf, scid->cid_len);
    engine->scid_buf[scid->cid_len * 2] = '\0';
    return engine->scid_buf;
}

Thus there are 2 issues:

• xquic 1.8.0 is not compatible with Tengine
• documentation doesn't reflect actual API, not updated
