Tevin Zhang 0d34068678 Use 10.255.255.1:80 as an always-timeout address 
Since 10.0.0.0:1 causes ErrConnect(permission denied) instead of ErrTimeout in Travis CI's macOS environment.

Tevin Zhang a89fc1fe18 Refactor 
Significant changes:

1. `NewChecker()` accepts no argument, `zeroLinger` is enabled by default
2. Optional parameter `zeroLinger` in `CheckAddr()` turned into `CheckerAddrZeroLinger()`
3. `InitChecker()` -> `CheckingLoop(context)`
4. `ErrNotInitialized` -> `ErrCheckerAlreadyStarted`
5. Fewer system call calling, e.g. `connect()` is called exactly once per check
6. Epoll is now edge-triggered

 2016-10-18 21:00:00 +08:00
Tevin Zhang 882b0fcc11 A lot of adjustments 
1. 'shaker' renamed to 'check', should have named the repo to
tcp-checker
2. Add NewChecker() for creation
3. Add parameter zeroLinger
4. More error handling (Error from syscall.Close is returned)
