libs/asm-xml: add the AsmXml XML parser as xml.obj

AsmXml 1.4 by Marc Kerbiquet (BSD 3-clause, tibleiz.net), unmodified,
with a KolibriOS wrapper: COFF export table, lib_init and cdecl
adapters for the heap functions passed by the loader. It exports
lib_init and the ax_* functions used by FeedFlow and by the C--
header lib/obj/xml.h, and is shipped as /sys/lib/xml.obj.
