This does not buy us new functionnality for now, because we still have to discover how mach_init (which acts as a name server, enabling processes to discover each other's ports) is able to receive messages from other processes (this is a bootstrap problem, and the bootstrap port might be the place to search). While we are there: - removed a lot of debug which is now available using ktrace. - reworked message handling to avoid mutliple copyin/copyout of the same data. ktrace of Mach message now uses the in-kernel copy of the message instead of copying it from userland. - packed mach trap handlers arguments into a structure to avoid modifying everything next time we have to add an argument.
