This initial prototype is capable of performing DC, transient and AC
analysis. Not all features of OSDI are supported yet and there are still
some open questions regarding ngspice integration. However many usecase
already work very well and a large amount of CMC models are supported.
The biggest missing feature right now is noise analysis.

feat: use osdi command to load files
Previously OSDI shared object files were loaded from fixed directories.
This was unreliable, inconvenient and caused conflicts with XSPICE.
This commit remove the old loading mechanism and instead introduces the
`osdi` command that can load (a list of) osdi object files (like the
codemodel command for XSPICE). A typical usecase will use this as a
precommand in the netlist:
.control
pre_osdi foo.osdi
.endc
If the specified file is a relative path it is first resolved relative
to the parent directory of the netlist. If the osdi command is invoked
from the interactive prompt the file is resolved relative to the current
working directory instead.
This commit also moves osdi from the devices folder to the root src
folder like xspice. This better reflects the role of the code as users
may otherthwise (mistakenly) assume that osdi is just another
handwritten model.

fixes for compilation on windows
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
Write current node voltages to file in format .ic=value
The file may be used to set initial conditions for another simulation,
e.g. ac at a specific time step of a transient simulation.
Write out the right hand side status of the matrix in format
.ic = V(node_xx)
This may be possible at the end of a simulation or after a 'stop'
of the simulation, which may be resumed again afterwars. This
status may be used to start another simulation with these
parameters by inluding into the netlist.
from times cut-tstart to cut-tstop and copy these
into a new tran plot. A new scale vector 'time' will be
generated as well. Vectors that are shorter than the
new scale vector will not be copied.
add command 'alterparam paramname=pvalue'
to change a global .param
add command 'alterparam subcktname pname=vpval'
to change a parameter inside of a subcircuit
For developing purpose only, and bound to HAVE_TSEARCH, HAVE_TDESTROY
IFparm descriptors must obey certain contracts,
1) aliases must be grouped together with their associated main descriptor,
and all must have flag IF_REDUNDANT set
2) there shall be no duplicated .id fields except for aliases.
3) aliased entries shall have consistent .dataType fields
check_ifparm will traverse all IFparm sets and report violations
