as variables owned by somebody else, e.g. from ft_curckt->ci_vars.
The new function parameter tbfreed notifies the caller if the
variable is malloced here and may be freed safely.

Functions to add, remove, retrive dicoS from the list
and to update dicoS, if the circuit has been changed.
Keeping dicoS is necessary because it may be used by measure.
This patch prevents (huge) memory leaks by overwriting
dicoS if multiple calls to the 'source' command are executed.
currently each and every device specific instance and model structure
duplicates the memory layout of a struct GENmodel / GENinstance
further the first structure elements behind a GENinstance header
are reinterpreted as a sort of a generic "node" array.
This business is very error prone, and makes it difficult to
extend struct GENmodel / struct GENinstance.
This patch makes this business much more bearable.
loop over DEVmodDelete() and DEVdelete() in CKTdestroy()
instead of doing this business in the DEVdestroy() functions.
As a consequence, most DEVdestroy() functions
collapse completely.
Instead of searching and then deleting a given device-model,
just delete the given model.
The search shall be done somewhere else.
Don't free the model struct itself,
this shall be done by the invoker himself.
Don't free the device instrance list,
this shall be done by the invoker himself.
As a consequence, most DEVmodDelete() functions
collapse almost completely.
This change is of no consequence,
because DEVmodDelete() is currently nowhere used.

Prevent a crash of example/FFT_test.cir.
Buffer 'buf' in function drawlingrid() has been too small.
Increase 'buf' size, and add some protection.
The example file examples/plot/test-small-plot.cir
shows the limits of plotting:
difference in two numbers at digit 14 is plotted well.
at digit 15 is plotted with bugs.
at digit 16 is reduced to integer.
