Remove dependencies on vvp_bit4_encoding outside of the vvp_net
core types. The table_functor_s class was the worst offfender and
was barely used, so it is now removed completely. There are a few
opcodes in vhtread.cc that also make vvvp_bit4_t encoding
assumptions (and used casts) and those have been fixed. There
were also various VPI interface functions that are fixed.
vpi_put_value can mimic force and release with vpiForceFlag and
vpiReleaseFlag flags to the vpi_put_value call. With this patch,
the infrastructure is added to allow the flags argument to be passed
to the dispatched put_value function, and for signals handle those
flags as force/release of a net.
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.
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()).
Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.
