Security: Fix resolving of some relative paths
Trying to resolve a path with RemoveRelativePathComponents that can't
be resolved without leaving leading parent components (e.g. "../worlds/foo"
or "bar/../../worlds/foo") will fail. To work around this, we leave
the relative components and simply remove the trailing components one
at a time, and bail out when we find a parent component. This will
still fail for paths like "worlds/foo/noexist/../auth.txt" (the path
before the last parent component must not exist), but this is fine
since you won't be able to open a file with a path like that anyways
(the O.S. will determine that the path doesn't exist.
Try `cat /a/../etc/passwd`).

Cavegen: Wider tunnels in mgflat, mgfractal, mgvalleys
As mgv7 is now the default mapgen i re-checked its tunnel width on request,
discovered they needed to be wider, and have made this change.
This commit widens the identical 3D noise tunnels in the other mapgens in
exactly the same way.
Mod dependency lists: Should have platform-independent line breaking
This fixes a bug existing in modmgr.lua as reported by @Wuzzy2 which
caused the mod dependency list to glitch if input was using a line
terminator different than the OS default.
The C++ code does not need any changes as it already trims CR
occurrences on platforms on which the line termination sequence is LF.
Taken into account the size of the depends.txt files used, this should
not introduce a noticeable performance regression.

Fix computation of viewing range (in blocks) sent to server (#4882)
Fixes #4878
Also remove an artificial viewing range reduction that
(presumably) was added to compensate for miscomputed
viewing ranges, and that doesn't seem to be needed any
more (thanks to lhofhansl).

Simple deco: Allow setting param2 value on placement
Schematics can already be placed with a param2 value, but not
simple 1-node plant decorations of the simple type.
This adds a `param2` field to the simple deco type that is
checked to be between 0 and 255, and put to the placed node
at mapgen.
This can be used to put a degrotate value in, or e.g. a fill
value for leveltype nodes, or a place_param2 value at mapgen
placement, or vary the shape of meshoptions plantlike drawtype.

Liquids: Preserve flow state if 'ignore' is a neighbour
Prevent waterfalls from falling down or streams from flowing away when the
source node is in an unloaded block - Nodes near a CONTENT_IGNORE node will
be interpreted as if the ignored node is a liquid node that just supports
the current state of the nodes in question.

Biomes: Increase heat and humidity noise spread to 1000
To avoid smaller biomes when extra biomes are added to MTGame.
The addition of bushes in MTGame grasslands makes wood resources easier
to find and less distant, so slightly larger biomes are now acceptable,
but also desirable to encourage travel and create more sense of adventure.

Mgv7 floatlands: Various improvements
Floatland base terrain underside was too thin, causing excessive water
leakage through tunnels under lakes, now make it thicker.
Floatland mountain terrain had a rim 1 node thick which made it bare
stone, now make it 2 nodes thick to merge with the floatland base
terrain rim and to have a layer of biome material.
Make mountain terrain more exponentially shaped by altering the
exponent.
Remove unnecessary and potentially ugly MYMAX() applied to
n_base_height.

Allow restricting detached inventories to one player
This combats the problem of sending the hundreds of

Fix fs::RemoveRelativePathComponents for paths with a leading dot component
Previously, paths like ./worlds would be resolved to /worlds since the
leading dot was considered just as irrelevant as a dot in the middle of

Particles: Make attached particle spawners respect the parent's yaw
Position, velocity and acceleration vectors of particles are rotated
by the yaw of the parent object so that they are truly relative to it.
