Corrected a major error with the verilog parser. The verilog 

parser was not assigning the correct file number for the first
input file, which resulted in the effect that if the first
file read sets definitions for the netlist, then those definitions
are wiped out on the following file read.  There has been a workaround
to read from /dev/null on the first file read so that the file number
is set on all subsequent reads.  This fix avoids the need for the
workaround.
