* loader/libcrt/string.h: Add required prototypes (strcat and

* loader/libcrt/strcpy.c (strcat): New function.

* loader/libcrt/strrchr.c (strrchr): Added new standard strrchr
function needed by the EXPORT_FUNCTION_RESTRICTED system.

* loader/libcrt/Makefile (OBJS): Added the new strrchr.o object

* loader/elf32/link.c (relocate_section): Added the necessary code
to lookup for symbol that are either exported using
building the string of the form "module:symbolname", and looking
in the exported symbol database for symbol "symbolname" and symbol

* loader/mod.h (EXPORT_FUNCTION_RESTRICTED) : This new macro
allows to export a symbol to a single module instead to all
modules. For example EXPORT_FUNCTION_RESTRICTED(foo, vmm) will
only allow the vmm module to access the foo symbol. Basically,
this macro creates an exported symbol named "module:symbolname".
