Added geom indexing environment options

T38IDXGEOM  -- Point threshold for indexing geometry
T38IDXMULTI -- Child threshold for indexing multi/collection

Default is 64
Using zero will disable indexing

Example:

T38IDXGEOM=0 tile38-server    # disables geometry indexing
T38IDXGEOM=256 tile38-server  # indexing geometries 256+ points
