e897f28b00 xserver's priv proc is responsible for opening devices in O_RDWR mode and send 
their fds over to the parent proc. Knowing this then we already have a list of
all possible devices that might be opened in the future, in struct okdev
allowed_devices[], and we just need to traverse them and unveil(2) each one
with read/write permissions.

positive feedback from semarie@, OK matthieu@

d9aef29941 set MSG_CMSG_CLOEXEC when receiving file descriptors. 
All file descriptors opened via priv_open_device() can benefit of
the close-on-exec flag.

fe08a081d8 MFC: os: Make sure big requests have sufficient length. 
A client can send a big request where the 32B "length" field has value
0. When the big request header is removed and the length corrected,
the value will underflow to 0xFFFFFFFF.  Functions processing the
request later will think that the client sent much more data and may
touch memory beyond the receive buffer.

3e477e765c Merge from upstream: Don't listen to 'tcp' by default. Add '-listen' option. 
commit cc59be38b7eff52a1d003b390f2994c73ee0b3e9
Author: Keith Packard <keithp@keithp.com>
Date:   Fri Sep 12 11:33:48 2014 -0700

    os: Don't listen to 'tcp' by default. Add '-listen' option. [v2]

    This disables the tcp listen socket by default. Then, it
    uses a new xtrans interface, TRANS(Listen), to provide a command line
    option to re-enable those if desired.

    v2: Leave unix socket enabled by default. Add configure options.

c7c0180b4c In non-privilege sepration mode, avoid accidentally sending 
a SIGUSR1 signal to init(8).

It can happen that xdm dies before the X server that it started.
In that case X's is reparented by init...

This is handled correctly when privilege separation is not compiled
but got overlooked in the privilege separation case.

b9f30b39b5 Remove warnings emitted when a device can't be opened. This
