Seth Hillbrand 6bb89dac01 Implement MIFnoise(), the generic noise callback for all XSPICE code 
models. Two discovery modes are supported: declarative, where models
define reserved parameter names (noise_voltage, noise_current,
noise_corner, noise_exponent) and get automatic noise sources and
programmatic, where models register sources via cm_noise_add_source()
during MIF_NOI analysis calls.

Keith OHara 0638aaa160 Continue Newton iteration until currents settle. 
For each type of device, a *convTest function determines if the
current through that device is converged within tolerance,
and sets CKTnoncon if the current is not yet converged.

ASCRconvTest() erroneously subtracted old current from old,
rather than old from new, when evaluating convergence.

Also, since at least 3f5, the calling function NIconvTest assumed
that the worker functions indicated non-convergence through their
return value, so was ignoring the reports of current nonconvergence.

Holger Vogt 864ee815bc Update VSRC and ISRC pulse sources 
Enable PW=0, improve 'incomplete' pulse specifications

TR negative or 0 --> TR = ckt->CKTstep

if PW not given, but TR and TF --> PW = 0
PW < 0 --> PW = ckt->CKTfinalTime
PER <= 0 --> PER = ckt->CKTfinalTime
