allocate_tls_tpfactory allowing creation transport using the same port

[MayamaTakeshi]

This code:

    const t1 = sip.transport.create({address: "127.0.0.1", type: 'tls'})
    const t2 = sip.transport.create({address: "127.0.0.1", type: 'tls'})

    console.log("t1", t1)
    console.log("t2", t2)

resulted in:

t1 { id: 0, address: '127.0.0.1', port: 6060 }
t2 { id: 1, address: '127.0.0.1', port: 6060 }

Need to check if this also happens with tcp.

[MayamaTakeshi]

I checked tcp and there is no problem. This code:

    t1 = sip.transport.create({address: "127.0.0.1", port: 6060, type: 'tcp'})
    t2 = sip.transport.create({address: "127.0.0.1", port: 6060, type: 'tcp'})

fails as expected:

allocate_tcp_tpfactory ipaddr=127.0.0.1 port=6060
allocate_tcp_tpfactory ipaddr=127.0.0.1 port=6060
status=120098
