SOILWAT2 Threadsafety and Reentrancy

[N1ckP3rsl3y]

• Updates to match SOILWAT2's reentrancy and threadsafety changes
• See https://github.com/DrylandEcology/SOILWAT2/pull/349

Changed base of this PR to release/devel_v6.0.1

because updating rSOILWAT2 to be compatible with SOILWAT2 v7.1.0 (thread-safety and reentrancy) will not affect the user interface and is expected to produce identical simulation output -> for rSOILWAT2, this is a patch and not a minor version increase
