Maybe you shoud use hio_alloc_readbuf，and hio_free_readbuf is called when hio_done.

HV_FREE already used in kcp_release(which will be called in hio_close -> hio_done ->rudp_cleanup->rudp_entry_free), so I called HV_ALLOC here

OK, I've reviewed it again, and the readbuf here is kcp_s own readbuf, unrelated to hio_s, and can be allocated here.

I add a member to kcp_setting_t so that it can allow recv larger package in kcp session.
I wonder whether it's reasonable or not, or larger package will rersult in some performace matter(maybe that's why it's not supported before)?
