Rémi Verschelde 1f6f364a56 Port member initialization from constructor to declaration (C++11)
Using `clang-tidy`'s `modernize-use-default-member-init` check and
manual review of the changes, and some extra manual changes that
`clang-tidy` failed to do.

Also went manually through all of `core` to find occurrences that
`clang-tidy` couldn't handle, especially all initializations done
in a constructor without using initializer lists.

Happy new year to the wonderful Godot community!

We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.

Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.

Fabio Alessandrelli feb54d0ed7 Make NetSockets quiter.

GDScript.

Fabio Alessandrelli d780570faf Use WSAConnect instead of connect on Windows.
The misterious windows networking stack...
Using connect instead of WSAConnect causes socket error 10022 under
certain conditions.
See: https://github.com/godotengine/webrtc-native/ (issue 6)
Having to guess, code path for connect is different then WSAConnect with
NULL extra parameters.
The only reference about weird error with this code mentions something
called "Windows Filtering Platform" but windows internals are, as
always, obscure.

This might be something to try and report to Microsoft if anyone has the
time to spare with the likely outcome of being ignored.

Merge pull request #32616 from Faless/net/fix_close_exec
Disable socket descriptor sharing with subprocs.

Fabio Alessandrelli 9c91b2051a Disable socket descriptor sharing with subprocs.
On Unix systems, sockets are like file descriptors, and file descriptors
are usually shared among child processes.
This means, that if we spawn a subprocess (or we fork) like we do in the
editor, open file descriptors will leak to the new process.
This causes issue with sockets as they might remain open and bound
(listening) when the original process closes.

Rémi Verschelde 68735d2a88 Fix compilation warnings in JS and Windows builds
Warnings raised by Emscripten 1.38.0 and MinGW64 5.0.4 / GCC 8.3.0.

JS can now build with `werror=yes warnings=extra`.
MinGW64 still has a few warnings to resolve with `warnings=extra`,
and only one with `warnings=all`.

Part of #29033 and #29801.

Fabio Alessandrelli 1ef9e9ef6a Properly accept wildcard when binding IPv4 socket.
Also never return null for is_ipv4 to avoid crashes due to engine bug.
(better to get an error and a broken socket then seeing your game crash)

Fabio Alessandrelli c37442ef00 Fix Winsock UDP ECONNRESET/ENETRESET bug
Since Windows 2000:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may result in a WSAECONNRESET error.

Since Windows Vista(?)/Windows Server 2008:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may also result in a WSAENETRESET error.

Both those features are disabled by this commit using disabling
SIO_UDP_CONNRESET and SIO_UDP_NETRESET on newly created UDP sockets.

Fabio Alessandrelli a15db2d2b6 Use select instead of WSAPoll on Windows.
WSAPoll is broken by design.
It was announced as the new way to introduce compatibility to posix
sockets, their implementation was broken, and they decided not to fix it.

Fabio Alessandrelli b4e3be7519 New NetSocket interface, BSD/Win implementation
Unified BSD and Winsock sockets into a single implementation of a
generic NetSocket interface.

This is some ground work for few network improvements:
- Reuse as much code as possible between Posix and Windows.
- Provide a single point of implementation for exotic sdks (consoles).
- Provide platform agnostic StreamPeerTCP and PacketPeerUDP in core.
- Implement connect for UDP allowing for DTLS implementation.
