Fix Fragmentaion Issue

[razimograbi]

Summary

related to issue: #13

I replaced the standard epoll logic with EPOLLONESHOT.

In order to test the fragmentation run the server on debug mode and then open PowerShell and past this command:

$client = New-Object System.Net.Sockets.TcpClient("localhost", 6625)
$stream = $client.GetStream()
$writer = New-Object System.IO.StreamWriter($stream)

while ($true) {
    Write-Host -NoNewline "> "
    $cmd = [Console]::ReadLine()
    
    # Converts literal '\n' to real newline byte (0x0A) and '\r' to carriage return (0x0D)
    $parsed = $cmd.Replace('\n', "`n").Replace('\r', "`r")
    
    $writer.Write($parsed)
    $writer.Flush()
}

Start sending inputs and then at the end add a \n so we can actually see that it works.

No sure if we can simply check the last character and that's it. hmmmm,
Can the command buffer be populated by other thread ? Because we are using EPOLLONESHOT I don't think so.
Might be able to optimize it to O(1)
