[Net] Fix Marshalls infinite recursion crash.
Variants like dictionaries and arrays can have cyclic references, which
caused `encode_variant` to run an infinite recursion.
Instead of keeping a stack and looking for cyclic references which would
make serialization slower, this commit adds a `MAX_RECURSION_DEPTH`
constant to Variant, and have `encode_variant` keep track of the current
recursion depth, bailing when it's too high since this likely means a
cyclic reference has been encountered.

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.

Backport of #48239.

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 🎆

GDScript: Validate object instance on is operation
Avoids crashes on debug mode. Instead it now breaks the execution and
show the error in-editor. Will still crash on release.

Also add a similar check to Marshalls to ensure the debugger doesn't
crash when trying to serialize the invalid instance.

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.

changes).

e61a074a8e Use same boolean for objects encode and decode.
In a very unintuitive move encode needed false to encode an object,
decode needed true to decode it.
They now need the same value: `true`.

7b081a7fc8 Fix warnings about unhandled enum value in switch [-Wswitch]
Fixes GCC 5 warnings of the form:

core/io/marshalls.cpp:806:9: warning: enumeration value 'AABB' not handled in switch [-Wswitch]

Those can be trivial cases where adding a default fallback is the solution,
or more complex issues/hidden bugs where missed values are actually meant
to be handled.

feaf03421d Fix marshalls size checks.
Yesterday, when playing around with my network code, I realized there is
a security issue in decode_variant, at least when decoding PoolArrays.
Basically, the size of the PoolArray is encoded in a uint32_t, when
decoding it, that value is cast to int when comparing if the packet is
actually that size causing numbers with MSB=1 to be interpreted as
negative thus always passing the check. That same value though, is used
as uint32_t again to resize the output vector.  For this reason, sending
a malformed packet with declared type PoolByteArray and size of 2^31(+x)
causes the engine to try to allocate 2+GB of pool memory, causing the
engine to crash.

cacced7e50 Convert Object::cast_to() to the static version
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.

This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.

It is explained in this article: https://www.viva64.com/en/b/0226/
