Most conversion codes in the scanf routines are supposed to
skip leading space. This patch adds that functionality.
(cherry picked from commit e987162cb9)
This patch adds compiletf routines for the $sscanf/$fscanf
functions. It does not enhance the conversion routines it
only adds better error/warning messages.
It also removed the redundant IS_MCD in some of the fileio
calltf routines. This is already checked in vpi_get_file().
I also added the vpiNetArray type to allow us to distinguish
arrays of nets from other arrays (memories). Much more is
needed here, but this solved the problem of the day. The
problem was that we needed to make sure we could assign to
the word of a variable array, but not the word of a net array.
It's actually probably not needed since Icarus converts the
net array word reference to just the net, but I thought it
prudent to make sure things didn't slip by.
The old code returns a vpiIntVal for $fscanf("%d") format strings. This
limits the maximum input range arbitrarily to 32 bit.
This patch implements %d parsing similiar to %b and %x.
'?' and 'X' chars are not accepted for %d format.
