f1c81557dc #2605: Add safety check for type casting for QUIC dialer 
Issue #2605 brought up real problem that QUIC dialer doesn't support sockopt at the moment. Inside `internet.DialSystem(...)` function, one of the branch that involves `redirect(...)` returns `cnc.connection` instance that is currently unhandled by the code logic, and thus caused program panic during runtime.

It seems the sockopt support for QUIC protocol requires a couple changes including making `cnc.connection` public, such that we can handle in dialer, along with some thorough tests, this commit simply adds safety check to explicity state the fact that QUIC isn't working with sockopt. And the implementation of the feature can be scheduled later on.

* Separate TcpKeepAliveIdle and TcpKeepAliveInterval check logic

* Disable tcp keepAlive when TcpKeepAliveIdle < 0 and  TcpKeepAliveInterval <= 0

Quic related improvements (#915) 
* DialSystem for Quic

DialSystem() is needed in case of Android client,
where the raw conn is protected for vpn service

* Fix client dialer log

Log such as:
tunneling request to tcp:www.google.com:80 via tcp:x.x.x.x:443
the second "tcp" is misleading when using mKcp or quic transport

Remove the second "tcp" and add the correct logging for transport dialer:
- transport/internet/tcp: dialing TCP to tcp:x.x.x.x:443
- transport/internet/quic: dialing quic to udp:x.x.x.x:443

* Quic new stream allocation mode

Currently this is how Quic works: client muxing all tcp and udp traffic through a single session, when there are more than 32 running streams in the session,
the next stream request will fail and open with a new session (port). Imagine lineup the session from left to right:
 |
 |  |
 |  |  |

As the streams finishes, we still open stream from the left, original session. So the base session will always be there and new sessions on the right come and go.
However, either due to QOS or bugs in Quic implementation, the traffic "wear out" the base session. It will become slower and in the end not receiving any data from server side.
I couldn't figure out a solution for this problem at the moment, as a workaround:
       |  |
    |  |  |
 |  |  |

I came up with this new stream allocation mode, that it will never open new streams in the old sessions, but only from current or new session from right.
The keeplive config is turned off from server and client side. This way old sessions will natually close and new sessions keep generating.
Note the frequency of new session is still controlled by the server side. Server can assign a large max stream limit. In this case the new allocation mode will be similar to the current mode.
