Fabio Alessandrelli 8ffb7699af [mbedTLS] Enable TLS 1.3 support
Move library initialization to module registration functions.

Only set library debug threshold when verbose output is enabled.

TLSv1.3 functions seems to be a bit more verbose then expected, and
generate a lot of noise. Yet, some level of debugging without
recompiling the engine would be nice. We should discuss this upstream.

Lyuma 40fa684c18 mbedTLS: Update to new LTS v3.6.0
Keep module compatibility with mbedtls 2.x (old LTS branch).

A patch has been added to allow compiling after removing all the `psa_*`
files from the library folder (will look into upstreaming it).

Note: mbedTLS 3.6 finally enabled TLSv1.3 by default, but it requires
some module changes, and to enable PSA crypto (new "standard" API
specification), so it might be best done in a separate commit/PR.

mbedtls: Improve X509 certificate load error handling
Positive numbers shouldn't be treated as a hard failure:

> For CRTs in PEM encoding, the function parses permissively:
> if at least one certificate can be parsed, the function
> returns the number of certificates for which parsing failed
> (hence \c 0 if all certificates were parsed successfully).
> If no certificate could be parsed, the function returns
> the first (negative) error encountered during parsing.

Fixes #77994.

Style: Harmonize header includes in modules
This applies our existing style guide, and adds a new rule to that style
guide for modular components such as platform ports and modules:

Includes from the platform port or module ("local" includes) should be listed
first in their own block using relative paths, before Godot's "core" includes
which use "absolute" (project folder relative) paths, and finally thirdparty
includes.

Includes in `#ifdef`s come after their relevant section, i.e. the overall
structure is:

- Local includes
  * Conditional local includes
- Core includes
  * Conditional core includes
- Thirdparty includes
  * Conditional thirdparty includes

Fabio Alessandrelli 6fd9982358 [TLS] Add support for platform-specific CA bundles.
Adds a new OS::get_system_ca_certs method which can be implemented by
platforms to retrieve the list of trusted CA certificates using OS
specific APIs.

The function should return the certificates in PEM format, and is
currently implemented for Windows/macOS/LinuxBSD(*)/Android.

mbedTLS will fall back to bundled certificates when the OS returns no
certificates.

(*) LinuxBSD does not have a standardized certificates store location.
    The current implementation will test for common locations and may
    return an empty string on some distributions (falling back to the
    bundled certificates).

Fabio Alessandrelli 024a4b1f2a mbedTLS: disable weak crypto and TLS versions.
This commit adds a new mbedTLS configuration header to customize the
built-in library (and can be optionally replaced by a platform-specific
one).

Currently, it disables most weak cryptographic functions (with the
notable exceptions of MD5 and SHA-1), along with removing support for
TLS versions 1.0 and 1.1 (making TLSv1.2 the only supported one).

Fabio Alessandrelli 7cd80e6a6d [Net] Remove StreamPeerTLS.blocking_handshake option.
Which was unused internally, and can be replaced by:

  tls.poll()
```

Fabio Alessandrelli adba870534 [NET] Refactor TLS configuration.
Use a TLSOptions configuration object which is created via static
functions.

- "TLSOptions.client": uses the standard CA and common name verification.
- "TLSOptions.client_unsafe": uses optional CA verification (i.e. if specified)
- "TLSOptions.server": is the standard server configuration (chain + key)

This will allow us to expand the TLS configuration options to include
e.g. mutual authentication without bloating the classes that uses
StreamPeerTLS and PacketPeerDTLS as underlying peers.

One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

Fabio Alessandrelli 331f1662df [Net] Drop is_connected_to_host for TCP and UDP.
The UDP method is now called `is_socket_connected` to limit confusion
with the actual host connection status which doesn't make sense in UDP.

The TCP method is completly dropped, use get_status instead.

The only one left is the WebSocketPeer one, which should be fine as is
for now.

Make all file access 64-bit (uint64_t)
This changes the types of a big number of variables.

General rules:
- Using `uint64_t` in general. We also considered `int64_t` but eventually
  settled on keeping it unsigned, which is also closer to what one would expect
  with `size_t`/`off_t`.
- We only keep `int64_t` for `seek_end` (takes a negative offset from the end)
  and for the `Variant` bindings, since `Variant::INT` is `int64_t`. This means
  we only need to guard against passing negative values in `core_bind.cpp`.
- Using `uint32_t` integers for concepts not needing such a huge range, like
  pages, blocks, etc.

In addition:
- Improve usage of integer types in some related places; namely, `DirAccess`,
  core binds.

Note:
- On Windows, `_ftelli64` reports invalid values when using 32-bit MinGW with
  version < 8.0. This was an upstream bug fixed in 8.0. It breaks support for
  big files on 32-bit Windows builds made with that toolchain. We might add a
  workaround.

Fixes #44363.
Fixes godotengine/godot-proposals#400.

Core: Drop custom copymem/zeromem defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆
