FIxed the way rights are recycled: the refcount makes only sense for send, send once, and dead names, not for port sets and receive rights. This make vi and telnet able to work again. Also removed the all process right list and its lock, which got useless. The all process lock is replaced by a per process lock, located in struct mach_emuldata. Also one bug fix: we did not correctly called Mach hooks for struct emuldata initialization and release for Darwin processes.

#ifndef _MACH_EXEC_H_
#define _MACH_EXEC_H_
Added implementation for cthread_self() and cthread_set_self(). Theses are used to get and set the thread user value, which is an opaque pointer to a per thread structure stored in userland. cthread_self() is used by Darwin as an implementation for pthread_self(), which return the thread id. We use the p_emuldata field of struct proc in order to keep track of the thread user value. For now the value is per-process, but we will make it per-thread when we will take care of threading. While we are there, do some KNF

struct mach_emuldata {
FIrst attempt at mach ports and rights, which are needed if we ever want to implement messages between kernel and userland. While we are there, cleanup some debug messages.

Several things: 1) rights should be shared by the threads within a process. While it would be easier to handle this with the struct proc/struct lwp split, we attempt to do this now by sharing the right lists. Because each right holds a reference to struct proc, this might cause some problems later. 2) in pthread_exit, really exit the thread. Also reintialize the righ tlist to make sure we will not destroy the parent's right list 3) rights can hold multiple permissions on a port (ie: send and receive). Fix th is. 4) first attempt on right carried by messages. We still have to do rights carrie d in the message body (complex messages).

First attempt on mach ports sets. Also maitian only one list of rights per process, as segregating recv, send and send_once did not buy anything.
