allow 'temper' keyword in .param, .model and device instance lines 

inpcom.c: fcns inp_fix_temper_in_param(), inp_new_func(), inp_rem_func()
  to convert .param with 'temper' to .func, and replace all affected
  parameter tokens xxx by their func counterpart xxx()

inpcom.c; fcns inp_temper_compat(), inp_modify_exp() added
  to prepare expression with 'temper' for numparam

inp.c: fcns inp_parse_temper(), inp_parse_temper_trees() added

inp_evaluate_temper()
  to prepare, parse and evaluate the expressions containing 'temper'

cktdefs.h: add global variable to expressions with 'temper'

dctrcurv.c: add fcn inp_evaluate_temper()
   when temp has changed

Evaluate expressions containing 'temper' keyword, found in
.model lines or device instance lines.
Activity has four steps:
1) Prepare the expressions to survive numparam expansion
(see function inp_temper_compat() in inpcom.c). A global
variable expr_w_temper is set TRUE if any expression with
'temper' has been found.
2) After numparam insertion and subcircuit expansion,
get the expressions, store them with a place holder for the
pointer to the expression parse tree and a wordlist containing
device/model name, parameter name and a placeholder for the
evaluation result ready to be used by com_alter(mod) functions,
in linked lists modtlist (model) or devtlist (device instance).
(done function inp_parse_temper()).
3) After the circuit structure has been established, generate
the parse trees. We can do it only then because pointers to
ckt->CKTtemp and others are stored in the trees.
(done in function inp_parse_temper_trees()).
4) Evaluation of the parse trees is requested by calling function
inp_evaluate_temper(). The B Source parser is invoked here.
ckt->CKTtemp is used to replace the 'temper' token by the actual
circuit temperature. The evaluation results are added to the
wordlist, com_alter(mod) is called to set the new parameters
to the model parameters or device instance parameters.
