mach_port_move_member, mach_port_set_attributes, mach_task_set_special_port,

Added mach_thread_create_running, which creates a new Mach thread. It
provides the register context of the new thread. We use it in a child
function provided to fork1(). The child function is machine dependent and
is not yet implemented for i386.
The new thread crashes quickly, but at least it starts.
the passed device number to only contain lower 16 bits; older glibc
appears to pass some junk in upper bits sometimes, resulting in incorrect
device entries being created
Problem initially analyzed by Thor Lancelot Simon.
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.
compat/common, so that they can be shared by several emulations, and use
them for Darwin.
This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN
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
merge the two emul_irix structures; the only difference was
setregs function, which can be handled by exec-specific setregs hook
rename setregs_n32() to irix_n32_setregs(), and make it suitable
as the exec-specific setregs hook
make irix_check_exec() a macro now that just single compare
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.
XXX sligh code rearrangement was necessary, change not tested
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.
Only tested for COMPAT_LINUX, changes to other compat modules were
mechanical.

in alternative emul tree first, and updates interpreter pathname
if found there; if not found in alternative emul tree, pathname
without the emul prefix is checked, and error returned if the file
doesn't exist
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()
