3.13.1

• Added asserts that check whether sparsity pattern of Jacobian and Hessian as returned by TNLP are within range w.r.t. number of variables and constraints. (#350)
• TNLPAdapter::ResortBnds now initializes complete output arrays with 0.0 before filling in values for non-fixed variables. Use new argument clearorig to turn this off. (#352)
• bring back configure variables ADD_{C,CXX,F}FLAGS
• added configure option --enable-relocatable to make prefix in pkg-config files relative to pcfiledir (assuming that --libdir hasn't been set)
• bring back configall_system.h for build without config header
• minor fixes to buildsystem
