Remove the vpi object symbol table after compile.

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.

ASSIGN transfer data to scheduler efficiently/permalloc vvp_net_t objects. The vvp_net_t objects are never deleted, so overload the new operator to do a more space efficient permanent allocation. The %assign/v instruction copied the vvp_vector4_t object needlessly on its way to the scheduler. Eliminate that duplication.(cherry picked from commit d0f303463d74c82e41d8fa966b06c00448588c74)

Permallocate scheduler cells in chunks Scheduler cells are small objects that come and go in great quantities. Even though they are allocated and deallocated a lot, they tend to a steady state quantity, so put together a heap that is unique for each cell type. This heap actually saves memory overall because cells are allocated in chunks, thus eliminating allocator overhead, and they are pulled/pushed from/to a heap very quickly so that what overhead remains is slight and bounded.
