In nets, if system functions return a real value the function lookup
was getting the correct width, but was also setting the width to 0,
which confused down-stream net handling. Real-value system fuctions
have a width of 1. (1 real-valued scalar.)
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.
This patch schedules the input value change to .sfuns calls to avoid
potential recursion problems. It also cleans up two put_value calls
that did unneeded loops when putting VectorVals and the width was
greaten than 32 bits.
This patch adds a new flag to vvp "-n" that can be used to make
$stop and hence <Control-C> act like $finish. This may be desired
when using vvp in a non-interactive environment.
tgt-vvp/eval_expr.c uninitialized variables
vpi/sys_display.c uninitialized variables
vvp/vpi_priv.cc deprecated string constant usage
vvp/vpi_vthr_vector.cc deprecated string constant usage
the last entry invokes vpip_name_string() and uses const char *
in the same way as the other 9 callers in vvp/*.cc, the only
difference is that the argument is static instead of computed.

differences remain relative to upstream .h files:
whitespace

Regarding the latter, Tony writes "Don't worry about the .h file.
The only difference is a considerably larger initial hash size.
If this isn't a problem with Icarus now, it certainly doesn't
need to be bumped up."
Fix data type handling of module ports. When ports are declared
as ports and given data types in different statements, the parser
incorrectly (and silently) dropped the intended data type for the
default LOGIC type.
Rework the ivl_file_table_* interface to be more generic and easier
to use. Also all the vvp examples except for memory.vvp have been
fixed to run correctly with the current vvp. Someone with a bit more
experience will need to fix memory.vvp.
Add the vpiFile and vpiLineNo properties to system functions.
Most other objects have stubs that return "N/A"/0. Interactive
functions (called from the debugger) use <interactive> for the
file name.
Use the precompiled defines file support of the ivlpp preprocessor
to pass defines made in the main program to processed library modules.
In other words, a `define in the Verilog source will be visible to
library modules.
Core preprocessor support for writing out and reading precompiled
defines. The preprocessor can read initial precompiled defines from
any number of specified source files, and can write all the defines
into a specified output file.
With this change, local symbols are not emitted in the vvp target,
but are marked as local. When thus marked, the vvp run time does not
offfer any VPI access and the signals (net or var) are effectively
invisible.
Zero-based part selects are a special case that is handled with
optimized code. Properly handle the part select width to get the
desired padding.

The code to handle real functions using the PLI 1 interface was
missing some functionality. This patch fixes that and fixes a
bug in the veriuser.h include file.
The recent changes to vpi_get_str had a minor problem that was
causing a core dump when trying to get the vpiFullName of an
arrayed signal. Basically vpi_get_str is not reentrant so the
name must be duplicated. It must also be duplicated to work with
the free in the code (do not free a result_buf).
Add support for a default, standard, implicit include directory
in the base directory for the ivl installation, where standardized
Verilog header files may be placed.
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.
Gets rid of a few warning: deprecated conversion from string
constant to 'char*', follows IEEE 1364-2001C 27.10 in more cases,
and fixes at least one real bug (look at the previous use of
strdup/strcat in real_var_get_str() and signal_get_str()).
