Introduce a new contentfeatures version (8). When clients
connect using v27 protocol version, they can assume that
the tiledef.backface_culling is trustable, but if clients
connect to servers providing contentfeatures version 7,
then the v27 clients know that backface culling settings
provided by the server in tiledefs are bogus for mesh,
plantlike, firelike or liquid drawtype nodes.
thanks to hmmmm, est31, nerzhul.
Tested on new client - new server, new client - old server
old client - new server.

Outdated servers are always sending tiledefs with culling
enabled no matter what, as the value was previously entirely
ignored.
To compensate, we must (1) detect that we're running against
an old server with a new client, and (2) disable culling for
mesh, plantlike, firelike and liquid draw types no matter what
the server is telling us.
In order to achieve this, we need to bump the protocol version
since we cannot rely on the tiledef version, and test for it
being older. I've bumped the protocol version, although that
should have likely happened in the actual change that introduced
the new backface_culling PR #3578. Fortunately that's only 2
commits back at this point.
We also explicitly test for the drawtype to assure we are not
changing the culling value for other nodes, where it should
remain enabled.
This was tested against various pub servers, including 0.4.13 and
0.4.12.
Fixes #3598

Add new node property 'floodable', default false
Define "air" as floodable = true in C++ and lua
|
|
This might break some mods, but it is important for all uses of the param2 to
be documented.
This doesn't need a serialisation version or network protocol version change,
as old clients will still work on new servers, and it is bearable to have
new clients getting non rotated plants on old servers.

This simplifies NodeResolver logic and makes some interfaces cleaner.
|
|
- Add ability to explicitly reset NodeResolve state (useful for unittesting)
- Remove non-essential NodeResolve methods modifying state from INodeDefManager
- Add const qualifier to NodeDefManager and ContentFeatures serialize
|
|
NodeResolver name lists now belong to the NodeResolver object instead of
the associated NodeDefManager. In addition to minimizing unnecessary
abstraction and overhead, this move permits NodeResolvers to look up nodes
that they had previously set pending for resolution. So far, this
functionality has been used in the case of schematics for
serialization/deserialization.

std::vector on Environment.cpp"
This reverts parts of commit 9749d9fee6db99da1ab861dc04ec63ef973db3e0, which breaks node resolver
list clearing

This way flowing liquids actually show the backface when specified to
do so. Without this, TileDefs where by default initialized with
backface_culling = true and never set otherwise.
For backwards compatibility, an old client connected to a new server,
or a new client connected to an old server will behave like before
i.e., backface_culling is always true.
