Split the 16dae.c source file into multiple files

[casella]

When compiling large models with -daeMode=new, the lion's share of the compilation time on machines with multiple cores is taken by the 16dae.c file. This contains

• a large number of simple functions, each computing a residual
• the evaluateDAEResiduals function
• the getAlgebraicDAEVarNominals function
• the setAlgebraicDAEVars function
• the getAlgebraicDAEVars function
• the initializeDAEmodeData function

I would recommend at the very least to put each of the last five functions in separate C source files. It would also be good to split the first part of the file, containing the residual functions, in multiple chunks, as already done for the 06inz.c file, see ticket:3963#comment:6. This would dramatically speed up the code generation for large models, where C compilation is currently the bottleneck.

In fact, also the 12jac.c and 02nls.c files can take a very long time and should be split as well.

Probably it would be also worth to push all static information into an xml file and just read it once at runtime, here e.g. the sparsity pattern and the algebraic variables.
While splitting the equations in separated files should be done anyway.

Rescheduled to 1.14.0 after 1.13.0 releasee

[casella]

Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0
