2022-04-15net: use Sock::SetSockOpt() instead of standalone SetSocketNoDelay()Vasil Dimov
Since the former is mockable, this makes it easier to test higher level code that sets the TCP_NODELAY flag.

Change `ConnectSocketDirectly()` to take a `Sock` argument instead of a bare `SOCKET`. With this, use the `Sock`'s (possibly mocked) methods `Connect()`, `Wait()` and `GetSockOpt()` instead of calling the OS functions directly.

2021-02-10style: rename hSocket to sockVasil Dimov
In the arguments of `InterruptibleRecv()`, `Socks5()` and `ConnectThroughProxy()` the variable `hSocket` was previously of type `SOCKET`, but has been changed to `Sock`. Thus rename it to `sock` to imply its type, to distinguish from other `SOCKET` variables and to abide to the coding style wrt variables' names.
2021-02-10net: use Sock in InterruptibleRecv() and Socks5()Vasil Dimov
Use the `Sock` class instead of `SOCKET` for `InterruptibleRecv()` and `Socks5()`. This way the `Socks5()` function can be tested by giving it a mocked instance of a socket. Co-authored-by: practicalswift <practicalswift@users.noreply.github.com>
2021-02-10net: add RAII socket and use it instead of bare SOCKETVasil Dimov
Introduce a class to manage the lifetime of a socket - when the object that contains the socket goes out of scope, the underlying socket will be closed. In addition, the new `Sock` class has a `Send()`, `Recv()` and `Wait()` methods that can be overridden by unit tests to mock the socket operations. The `Wait()` method also hides the `#ifdef USE_POLL poll() #else select() #endif` technique from higher level code.
2021-02-10net: move CloseSocket() from netbase to util/sockVasil Dimov
Move `CloseSocket()` (and `NetworkErrorString()` which it uses) from `netbase.{h,cpp}` to newly added `src/util/sock.{h,cpp}`. This is necessary in order to use `CloseSocket()` from a newly introduced Sock class (which will live in `src/util/sock.{h,cpp}`). `sock.{h,cpp}` cannot depend on netbase because netbase will depend on it.
2021-02-10net: move MillisToTimeval() from netbase to util/timeVasil Dimov
Move `MillisToTimeval()` from `netbase.{h,cpp}` to `src/util/system.{h,cpp}`. This is necessary in order to use `MillisToTimeval()` from a newly introduced `src/util/sock.{h,cpp}` which cannot depend on netbase because netbase will depend on it.
