File headers: SPDX License migration Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

Added a new internal header for implicit solver defines. Should become its own intern wrapper library eventually.

doxygen: add newline after \file While \file doesn't need an argument, it can't have another doxy command after it.

Moved "set_positions" for cloth out of core implicit solver. API for the solver now has functions for setting of vertex motion state and the associated root transform data.

Basic solver result feedback from the mass-spring (cloth/hair) solver. This returns a general status (success/no-convergence/other) along with basic statistics (min/max/average) for the error value and the number of iterations. It allows some general estimation of the simulation quality and detection of critical settings that could become a problem. Better visualization and extended feedback can follow later.

Cleanup: reduce indirect DNA header inclusion Remove DNA headers, using forward declarations where possible. Also removed duplicate header, header including it's self and unnecessary inclusion of libc system headers from BKE header.

void SIM_cloth_solver_set_volume(struct ClothModifierData *clmd);
Disable some debugging options in Eigen to make it more usable in Debug mode. Eigen can become very slow in debug mode, which is a bit of a problem. It relies heavily on compiler optimizations to remove function calls etc. More optimizations may be desirable, possibly putting the implicit solver into its own little library and enabling optimizations in debug mode there could help.
