Holger Vogt 631ff35c34 The 8th parameter on a voltage or current source now is 'number of pulses'. 
Previous usage had been PHASE, introduced by XSPICE, which has
been redundant to DELAY. PHASE is again available when compatibility flag
xs has been set.

Alessio Cacciatori 4ebf4901b9 S-parameters in ngspice 
With this commit the patch provided by Alessio Cacchiatori the S-parameter is completed:
Noise simulation added with C matrix output
Y and Z matrix output enabled

To allow compiling with gcc, the dense.h inline functions have been put into denseinlines.h

Holger Vogt cbf4305ff8 Remove the XSPICE dependency of the phase parameter for the 
independent voltage source.

Holger Vogt c88578e2c5 noise value is 0 for time == zero. 
Only when time changes from time == 0 to time > 0,
the 1/f noise data are generated once per voltage instance
with 1/f noise requested.
