ShadowNinja 77597c4ff3 Clean up numeric.h and split FacePositionCache from it 
I also optiized FacePositionCache a bit: I removed a map
lookup and vector copy from both branches of getFacePosition.

Ner'zhul 058a869b70 Permit usage of std::unordered_map & std::unorderered_set on c++11 compilers (#4430) 
This fallback to std::map & std::set for older compilers

Use UNORDERED_SET as an example in decoration and ore biome sets

Use UNORDERED_MAP as an example in nameidmapping

paramat 8591713405 Sheet Ore: Eliminate crash caused by PcgRandom range max < min 
In the calculation of y_start,
when 'column height max' was large it caused
nmin.Y + max_height > nmax.Y - max_height
Now, in this situation y_start is set to the
midpoint between nmin.Y and nmax.Y

Limit y0 and y1 to between nmin.Y and nmax.Y,
otherwise index calculation, which has no checks for limits,
places them at unwanted locations in the voxelmanip

kwolekr beba969413 Ore: Add ore sheet column height range selection 
Modders are now able to select the range of ore column height,
and the midpoint at which they 'grow' starting from.
This commit adds three new parameters for the 'sheet' ore type:
column_height_min, column_height_max, and column_midpoint_factor.
clust_size is now deprecated for this ore type.

kwolekr 479f38973e Schematics: Refactor NodeResolver and add NodeResolveMethod 
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.
