Alternative code for slipping (#6256)
* Alternative code for slipping
- does not depend on frame rate
- controllable via environment variables for now
* Adjust slipping speed for item entities too.
* Final version of framerate-independent slippery code
* Remove dead code and fix formatting
* getStandingNodePos should only look 0.05 nodes downwards
This ensures that, even if the player is standing on a partially
filled node, this node is used as the standing node and not the
node below it.
Specific use: enables slippery slabs
* Exchange global getStandingPosNode change for local inline change
Reverts previous commit
* Revert the item movement changes
* Slippery nodes now slip over cliffs and edges
Players no longer suddenly stop before falling off.
Also refactored slippery code into getSlipFactor method.
* Slipping over an edge gated by player's is_slipping state
A new flag for just this case, to reduce costly node lookups in
the normal case of leaning over a non-slippery edge.
Public access for consistency and potential future uses.
* Minor code tweaks / cosmetics
* Add temp variable to improve readability and fix indentation issues

Start off newly generated worlds early at sunrise, 5:15am (#6211)
Gives starting singleplayer games this subtle "dawn of a new world" feel.
I would have set it even earlier (up to 4:45am), but I was worried that in
some pre-existing games the player could be overwhelmed by hostile
mobs right at the start, seriously changing gameplay.
It's just the default, individual games should be able to override it, and
for public servers it's irrelevant anyway, because only the first player to
set foot in the world will notice, and that's usually the server admin.

Add tiny Y offset in collisionMoveSimple() to tweak performance
Another small general problem: the player is always standing exactly on the
bondary between 2 nodes e.g. Y=1.5 is exactly between nodes Y=1 and Y=2.
floatToInt() and myround() will round +/-n.5 always 'outwards' to +/-(n+1),
which means they behave differently depending on where you are: they round
upwards above sea level and downwards when underground. This inconsistency
comes from the way the coordinates are calculated, independent of the
specific C++ code.
The result is a tiny bit of lost performance when moving underground,
because 1 node level more than necessary is checked for collisions. This can
be amended by adding a tiny offset to minpos_f.Y, like @paramat suggested.
This is not an elegant solution, but still better than wasting CPU.

Fix player coordinate rounding in collisionMoveSimple() (#6197)
To determine the area (nodes) where a player movement took place
collisionMoveSimple() first took the old/new player coordinates and rounded
them to integers, then added the player character's collision box and
implicitely rounded the result. This has 2 problems:
Rounding the position and the box seperately, then adding the resulting
integers means you get twice the rounding error. And implicit rounding
always rounds towards 0.0, unlike floatToInt(), which rounds towards the
closest integer.
Previous (simplified) behavior: round(pos)+(int)box, for example player at
Y=0.9, body is 1.75m high: round(0.9)+(int)1.75 = 1+1 = 2.
==> A character's height of 1.75m always got rounded down to 1m, its width
of +/-0.3 even became 0.
Fixed by adding the floats first, then rounding properly: round(pos+box) =
round(0.9+1.75) = round(2.65) = 3.
