elf: Support __constructor and __destructor
The old way of specifying functions that need to be run before/after a main function has never worked for ELF modules. Instead, the only way to get similiar behaviour was by using the MODULE_INIT() and MODULE_EXIT() macros, but no one seems to have bothered converting the old __constructor users over. Anyway, the old way is superior because it allows multiple functions be specified. Delete the MODULE_* macros as there's only one user of them in the entire tree. We can also get rid of the UNKNOWN_MODULE constant because now a module doesn't need a __module_init_ptr symbol to be classed as a library - if a module isn't an executable, it's a library, there's no such thing as an unknown type. It's no longer necessary to explicitly call __syslinux_get_ipappend_strings() from ldlinux.c because the __constructor tag on the version in com32/lib/syslinux will take care of invoking it before ldlinux.c32's main() is executed. Also, since we've refactored unload_module() to now run a module's destructors let's minimise the number of callers by deleting load_library() and unload_library(), which were only called by the test module in com32/elflink.
