a901a56859 Dungeongen: Add and improve parameters
Add:
Bool for 'only_in_ground'.
Min and max corridor length.
Min and max room size with X, Y, Z components.
Min and max large room size with X, Y, Z components.

'only_in_ground = false' allows core mapgens to create structures
in air and water using dungeongen.
Corridor length parameters replace a fixed random range.
Room size parameters replace the former system where one parameter
'roomsize' was added to fixed random ranges.

All parameters are set for no change to current dungeon behaviour.

Remove some now-redundant and long-unused code.

2a89531071 Dungeongen: Fix selection of diagonal corridors
The do .. while loop is waiting for both dir.X and dir.Z to be non-zero,
so should continue to loop if either dir.X or dir.Z are zero. The brackets
present suggest this was intended to be OR not AND.

9f108b56d3 Dungeongen: Fix out-of-voxelmanip access segfault
My recent dungeon commit allowed stairs to be placed across the full
width of corridors, but some of the new node positions accessed were
missing checks for being within the voxelmanip, causing occasional
segfaults near dungeons with corridors wider than 1 node.

Add 'vm->m_area.contains(pos)' checks just before stair position
voxelmanip access. This allows an earlier check to be removed as it
is now redundant.

d413dfe87c Dungeons: Support nodebox stairs wider than 1 node
Previously, code did not support stair nodeboxes in corridors wider
than 1 node.
Make stair nodeboxes full width even in corridors with different
widths in X and Z directions.

04fb10914c Dungeons: Generalise use, add capabilities, various modifications
- Generalise node names to c_wall and c_alt_wall
- Remove 'mossratio' and instead disable alt_wall loop if
  c_alt_wall == CONTENT_IGNORE
- Use one generalised 3D noise for alternative wall nodes and in
  mgv6 create moss distribution similar to the previous

- Rename rarity noise to density noise and enable the option of multiple
  dungeons per chunk determined by the value. Recreate previous distribution
- Add parameters for min and max rooms per dungeon
- Add dungeon y limits

- Integrate river water properly

Generalisation is needed now that we have sandstone and desert stone
dungeons by default and can choose any node for alternative structure.
The current code is based around cobble dungeons with mossycobble
alternative nodes, the 2 noises controlling the alternative nodes
are based on wetness.

Enabling multiple dungeons per chunk with definable number of rooms
allows the option of very dense and complex underground structures
that could interconnect to create megastructures.
Y limits are added to be consistent with other mapgen elements, and
enable locaton of dungeon or megastructure realms as part of our
'stacked realms' philosophy.

b1eb757e60 Fix undefined evaluation order when constructing random vectors
MSVC and GCC evaluate parameters in right-to-left order, whereas Clang
evaluates in left-to-right order, and of course, an optimization could
leave the order of evaluation completely indeterminate.

This commit fixes all instances of the error by explicitly assigning the
results of expressions that use PseudoRandom::next() or range() to their
respective vector components.

The right-to-left evaluation behavior is preserved since Clang is much less
commonly used to compile Minetest than GCC and MSVC combined, and would
therefore cause the least harm.

57b429574e Dungeongen: Fix rarely triggered segfault
A segfault exposed a missing 'vm->m_area.contains()'
check in makeCorridor that allowed the calculation
of vm index for a node outside the vm area. The huge

5a34f40d80 Huge overhaul of the entire MapgenParams system
MapgenParams is no longer a polymorphic class, eliminating the need for messy and bug-prone reallocations.
Separation between the common and mapgen-specific parameters is now strongly defined.
Mapgen parameters objects are now properly encapsulated within the proper subsystems.
