Update header files to use a more standard name to prevent rereading This is from github report #16. There are likely a few more issues that need to be addressed though this takes care of the major ones.

#ifndef IVL_priv_H
#define IVL_priv_H
Add at least minimal implementations for several acc_ functions. Add support for standard ACC string handling. Add the _pli_types.h header file to carry the IEEE1364-2001 standard PLI type declarations.

/*
Rework libveriuser to make vpiSysTfCall handles available in callbacks. PLI 1.0 callbacks are directly associated with the instance of the system task/function that initiated them, allowing them to access the task/function arguments. However, we implement them using VPI callbacks, which are not so associated. So we need to pass the VPI handle for the associated task/function instance to the callback routine via the VPI callback user_data pointer, because vpi_handle(vpiSysTfCall, 0) will return null when called from the callback function. This is the first step to a proper fix for issue #141, to replace the problematic fix that was reverted in commit 8da8261f.

Fix fails to build with -fno-common or gcc-10 See also: https://bugs.gentoo.org/706366 gcc-10 and above flipped a default from -fcommon to -fno-common: https://gcc.gnu.org/PR85678 Usually all it takes is to add a few 'extern' declarations and move definitions from header files to modules. I've port iverilog to gcc-10 accroding to this guide: https://wiki.gentoo.org/wiki/Gcc_10_porting_notes/fno_common To fix this, I analyzed the code, and found ``pli_trace`` has been defined at here: https://github.com/steveicarus/iverilog/blob/v10_3/libveriuser/priv.c#L24 So I changed ``FILE* pli_trace;`` to ``extern FILE* pli_trace;``. The var ``current_file`` only in ``cfparse_misc.h``, I changed it from ``char *current_file;`` to ``extern char *current_file;`` and declaring it in cflexor.lex And then it works.
