98bc8767ae Bug fixes: 
- In case of ailure in the child, kill the child and wakeup the parent
- Do call child_return
- The src and dst args were mixed up when copying regs 0-31 to the trapframe

This makes pthread_create(3) fully working (test program works).

66a29c52af Added a few Mach traps: mach_boostrap_register, mach_port_set_attributes, 
mach_port_move_member, mach_port_set_attributes, mach_task_set_special_port,
(none do anything)
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.

78ea2dd367 Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out 
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

9f6565f2bd A working fork/vfork implementation. Darwin fork differs from our fork by 
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.

3b0f6d78ed Introduce BSD system calls with alternate patch checking (in /emul) in 
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

a9a3da8aca The recent mach trap support caused indirect system calls (a la syscall(2)) 
to be incorectly recorded as 'syscall'. Fix this.

The stack layout is observed from stack dumps on Darwin, so it should be

d584ed9598 Add a realcode argument to trace_enter and ktrsyscall. realcode is the 
original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

3a5d673363 Change syscall to bound code so that systrace and ktrace won't fall off 
the end of a table.   XXX this is wrong since code does not indicate the
sysent table for which code was used as an index.

85529376d3 Get rid of nsysent. Use EMULNAMEU to use the appropriate constant. 
Revamp the mach_syscall_dispatch function to be much simplier (pass in
a syscall code and return a const struct sysent * pointer).

873ed6f9ee Added support for Darwin's PowerPC-only system calls: 
ppccalls, with system call numbers starting at 0x6000
fasttraps, with system call numbers starting at 0x7FF0

Because the Mach system call dispatching code has grown a bit
too much, introduce an inline function to handle it (mach_syscall_dispatch).

While we are there, remove the Mach and Linux includes from
arch/powerpc/powerpc/syscall.c and push them into
arch/powerpc/powerpc/{mach|linux}_syscall.c
