Add TCPKeepAliveIdle in Sockopt option (#1166)
* Add TCP keep alive idle setting

* Add TCP keep alive idle setting: auto generated

* Add TCP keep alive support in Linux

* Add TCP keep alive support in MacOS, FreeBSD

* Add TCP keep alive support in Windows

* fix bug introduced in adding tcp keep alive adjustment

* embed macOS const to avoid platform inconsistency

* embed macOS const to avoid platform inconsistency(again)

* add TCP Keep Alive support in config

* use sys/unix instead of syscall

Suggestion from:
https://github.com/v2fly/v2ray-core/pull/1395#issuecomment-974761647

* use sys/unix instead of syscall

Suggestion from:
https://github.com/v2fly/v2ray-core/pull/1395#issuecomment-974761647

* Separate TcpKeepAliveIdle and TcpKeepAliveInterval check logic

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