- allow ICARUS_VPI_CONST to be pre-defined by the user
- use it for sizetf as well as for compiletf and calltf
- fix remaining warnings when it is defined as 'const'
119 formal void parameters added to keep -Wstrict-prototypes happy.
Process found one real missing prototype in vpi/vcd_priv.h:
EXTERN void vcd_names_delete(struct vcd_names_list_s*tab);
8 such warnings left, all in Tony's code

and a trivial patch to vpi_user.h to, among other things, make
ICARUS_VPI_CONST blank.
Thus, this patch does absolutely nothing. Will be followed by a
(much shorter) patch that makes it do something. :-)
vpi_config.h defines _FILE_OFFSET_BITS. This must be defined before
any system includes files are processed, so vpi_config.h must be
called first. This patch puts vpi_config.h first. It also removes
direct calls for both vpi_config.h and vpi_user.h when sys_priv.h
is included since it already includes these two files.
It also updates the code to always include vpi_user.h using double
quotes.
This patch adds support for iterating over the list of vpiUserSystf
tasks/functions that have vpiUserDefn set. The vpiUserDefn property
is true by default, but you can call vpip_make_systf_system_defined()
to set this property false (will hide the vpiUserSystf object). All
the normal system tasks/functions have been modified to call this
procedure to remove them from the list of vpiUserSystf objects. Only
user defined system tasks or functions should appear in the list.
vpi_compare_objects() is just a simple are the two pointers the
same. This works correctly for the vpiUserSystf objects, but the
other handle objects have not been checked.
This patch adds compiletf routines for the mti random functions
and adds a common routine to check for extra arguments. It also
adds file and line information to the rest of the compiletf
routines that were missing them.
This patch addresses a number of issues:
Rewrote the $test$plusargs and $value$plusargs routines to have
better error/warning messages, to support runtime strings, to
correctly load bit based values (truncating, padding, negative
value), added support for the real formats using strtod() and
added "x/X" as an alias for "h/H" to match the other part of
Icarus.
Rewrite the vpip_{bin,oct,hex}_str_to_vec4 routines to ignore
embedded "_" characters. Add support for a negative value and
set the entire value to 'bx if an invalid digit is found. A
warning is printed for this case.
Rewrite vpip_dec_str_to_vec4 to ignore embedded "_" characters,
to support a single "x" or "z" constant and to return 'bx if an
invalid digit is found. A warning is printed for this case.
It simplifies the system task/functions error/warning messages.
It removes the signed flag for the bin and dec string conversions.
This was not being used (was always false) and the new negative
value support makes this obsolete.
Add support for a real variable to handle Bin, Oct, Dec and Hex
strings. They are converted into a vvp_vector4_t which is then
converted to a real value.
Add support for setting a bit based value using a real value.
Removed an unneeded rfp signal in vpip_make_reg()
Several places in Icarus Verilog try to get the bits of the integer
part of a double by casting to unsigned or unsigned long. But that
causes some compilers to generate smart code that converts all values
less then 0 to 0, even though we are after the bits, not the math
value. So be careful to do this cast only to non-negative values and
uminus the bits if necessary to get exactly what we want.

This patch modifies the conversion functions $rtoi, $itor,
$realtobits and $bitstoreal calltf routines to be more efficient.
This is done by caching the vpiHandle to the argument in the userdata
pointer. This eliminated the need to get the argument iterator, scan
and free the iterator.
It also updates the error messages to use the new file and line
number information that is available for system functions. It also
adds a check that verifies the functions are only called with one
argument and makes the errors fatal.
