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.

/*
Fix for GitHub issue #98 and #167 Two fixes needed: - when searching for a base class, we need to look in the root scope if the base class isn't found in the scope hierarchy - the classes in the root scope need to be stored in an ordered list, not a map, to ensure they are elaborated in the order they were declared. Without this, the compiler may try elaborating an extended class before its base class is known about.

Remove malloc.h support and for C++ files use <c...> include files. The functions (malloc, free, etc.) that used to be provided in malloc.h are now provided in cstdlib for C++ files and stdlib.h for C files. Since we require a C99 compliant compiler it makes sense that malloc.h is no longer needed. This patch also modifies all the C++ files to use the <c...> version of the standard C header files (e.g. <cstdlib> vs <stdlib.h>). Some of the files used the C++ version and others did not. There are still a few other header changes that could be done, but this takes care of much of it.

Support separate compilation units in SystemVerilog. The compilation unit scope is now treated as a specialised form of package (with an automatically generated name). All items declared outside a design element are added to the current compilation unit package. Apart from when searching for a symbol, once we get into elaboration we can treat these just like any other package.

/*
First step towards supporting separate compilation units in SV. This adds a -u option to the driver to allow the user to specify that they want each source file to be treated as a separate compilation unit, and modifies the compiler to accept a list of files (either on the command line or via a file specified by a new -F option). This list of files is then preprocessed and parsed separately, causing all compiler directives (including macro definitions) to only apply to the file containing them, as required by the SystemVerilog standard.

* This code actually invokes the parser to make modules. If the path

* through the command specified by ivlpp_string before being parsed.

Add support for `resetall and other directive changes. This patch adds support for the `resetall directive. It also changes `celldefine, `endcelldefine and `resetall to no longer grab text following them. These directives do not take an argument so they should not be grabbing any text and silently discarding it. The `timescale processing was reworked to handle being reset and hooks were added to easily change the default time units and precision when we add that feature request.
