$time, $stime and $simtime return an integer rounded value for %f
...
The $time, $stime, $simtime (integer time) system functions should
return a rounded integer value in a real context.

Add file and line information to processes.

This patch adds file and line information to processes
(initial and always).

vvp_vector4_t words are unsigned long.
...
The double to vvp_vector4_t constructor was not using the correct
declaration for the bit words. This worked as long as unsigned and
unsigned long were the same size (usually).

Add a stub vvp_net_t::delete method
...
Some compilers reference the delete method for the vvp_net_t object
even though it is never used. So provide a stub with an assert.

Detect and elaborate AMS access functions.
...
Detect function call expressions that turn out to be calls to the
access function of a nature. Elaborate the access function and stub
the emit code. This gets the access function just short of the code
generator.

An included file should start at line 1.
...
The preprocessor was incorrectly setting the line when starting
an include file to the line it was called from instead of 1.
This would give incorrect line numbers for errors/warnings in
the included file.

Update real to int conversion: -inf is 'b0 not 'b1 like +inf.
...
The new real to int conversion was incorrectly setting the
bits for minus infinity to all ones. This is incorrect in a
two's complement encoding where the largest negative number
would be a leading 1 followed by an infinite number of zeros.

Update %cvt/vr to use new double to vector conversion (constructor).
...
This patch updates the %cvt/vr command to use the new double to vector
constructor. This allows the resulting bit pattern to be larger than
a long. The old method was producing incorrect results without a
warning for large bit values.

Make .part/pv strength aware and resolv vec8_pv aware.
...
This patch makes .part/pv strength aware, resolv vec8_pv
aware. vvp_net_fun_t adds vec8_pv as a virtual function
with an appropriate error default. vvp_fun_signal should
full support vec8_pv (not tested and may not be needed).

Use ivl_signal_dimensions to find arrays not ivl_signal_array_count
...
ivl_signal_dimensions() is the correct call to use to determine
if a signal is part of an array. If it is greater than zero the
signal is an array.

IVL_VT_LOGIC is default localparam type not IVL_VT_NO_TYPE
...
This patch fixes a bug where a local parameter with only a range
was incorrectly setting the default parameter type to IVL_VT_NO_TYPE.
This would create a compile time assert for any untyped
parameter/localparam immediately following it.

Some variable part select arguments must be drawn before the part select.

variable part select is printed e.g.(.array/port).
