When this parameters is set, then (some) prolongation/restriction operators are parallelized via LoopControl instead of in dh.cc.

Replace calls to abs() with floating arguments by calls to fabs(), to ensure the results are not accidentally truncated to integer.

Rewrite padding infrastructure.
Add padded array extents to transport operator APIs.

Extend API of grid operators and of gdata::copy_from,
gdata::transfer_from to allow hyperslabbing
Implement hyperslabbing in copy_3d.cc

Introduce a function gdata::allocated_memory_shape that determines from a given grid size how many grid points should be allocated. This allows adding padding to grid sizes, e.g. to improve cache performance.
Use this function when checking grid sizes.

single mechanism provided by CarpetLib.
Use this mechanism everywhere.

Ensure that there is exactly one OpenMP parallelisation for each
operator.
Improve the prolongation operator parallellisation method by splitting
along the direction of longest extent, not always in the z direction.
Use LoopControl for copy, restriction, and time interpolation
operators instead of explicit OpenMP directives.

Use #pragma instead of _Pragma for OpenMP directives. The PGI compilers do
not understand the _Pragma syntax.
Use int instead of ptrdiff_t for loop variables which are parallelised via
OpenMP. The PGI compilers cannot handle ptrdiff_t.

Add #pragma omp statements for loops in reduction and prolongation
operators. Change loop control variables to signed types.
Add functions to determine the number of active threads.
Add a parameter to set the number of threads if desired.
