Unknown temperature management updated

Stardis-Solver no longer uses negative values to define that a
temperature is unknown (commit Stardis-solver 75ae9b8). It now provides
the SDIS_TEMPERATURE_NONE macro. In fact, negative temperatures are now
valid for Stardis-Solver to calculate a relative temperature at a given
T in a linear situation.

This is a major break in the API, since the same entries before and
after the above-mentioned commit can correspond to two different
systems. This commit therefore replaces all negative values used as
unknown temperature with the new constant SDIS_TEMPERATURE_NONE.

We also correct the use of a negative value to define an unknown flux
when it should be set to SDIS_FLUX_NONE.
