Restructure the code a bit.
Two parameters for AM are required (offset and amplitude). Even if this
sounds needless, changing it would require a major effort.

Fix Bug #607 -

"DC Source with Pulse stops pulsing half way through simulation".
Do not require breakpoints to be hit almost exactly before scheduling
the next one. That may cause the next breakpoint to be lost.

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.

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
