Clean usage of void pointers to access symbols
Void pointers have been used to access linker symbols, by declaring an extern pointer, then taking the address of it. This limits symbols values to aligned pointer values. To remove this restriction an IMPORT_SYM macro has been introduced, which declares it as a char pointer and casts it to the required type.
