MAINT liblinear class label logic (disabled)

Pulled to make pulling in patches from upstream easier, but disabled with
an #if 0 block because I didn't know how this would interact with our own
modifications.  --LB

MAINT changes to (disabled) Liblinear code, from upstream

Was: f9c13dff5ad1b32e4a67eaed77c13365a86c68d7

In get_decfun_coef and get_decfun_bias, a zero value is returned in all invalid
cases. We decide not to return NaN because we are not sure if it can be
properly assigned in all platforms. (For example, ``double nan = 0.0/0.0;''
won't compile in Visual Studio.)
