2cd19ab0b2 - WindowServer wants io_master_port? Give it a port!
- introduce mach_port_destroy (badly emulated for now)
- on fork/exec, don't set l_private, as the process might be not mature
enough to survive a proc_representative_lwp call (-> kernel panic)

Once we give WindowServer the io_master_port, it sends a message to it:

   305 WindowServer MMSG  id 2804 [0x1310009 -> 0x131000e] -12016 bytes, flags 0

Did you ever dreamt about system call arguments in XML?

f656d621e7 Here we enter the land of IOKit where the shadows lie.
There are two new mach traps:
mach_vm_make_memory_entry, mach_host_get_io_master. Now we need to find
the documentation to understand what they are supposed to do.

5ba396cfb3 Added support for exchange of Mach messages between processes.
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.

0f239dc026 Check for alternate receive buffer for mach_msg_overwrite_trap
Check for target buffer length, and fail if it is too short
Move mach_msg_trap and mach_msg_overwrite_trap to their own file
Remove some useless debug messages now we have ktrace
Remove __P()

f9ddf42b17 the host basic info belongs with the cpu.
attempt to make the semaphore traps work, by doing nothing.
