Martin Schmölzer 5a005cefe2 "fsm_export" pass: fix KISS file generation. 
The KISS file format now follows the conventions specified in
"Logic Synthesis and Optimization Benchmarks User Guide", Version 3.0
by Saeyang Yang.

This change ensures interoperability with the "trfsmgen" program by Johann
Glaser.

Martin Schmölzer 4f6cda502d Add support for "fsm_export" synthesis attributes to fsm_export pass. 
This allows to specify the file name for exported files directly in the HDL
source via the fsm_export=... attribute on the FSM state register.

Verilog example:
    (* fsm_export="my_fsm.kiss2" *)
    reg [3:0] state;

The fsm_export pass now also accepts the option "-noauto". This causes only
FSMs with the fsm_export attribute to be exported, any other FSMs are ignored.
