Allow OutputClass config snippets to modify the module-path.
Note that any specified ModulePaths will be pre-pended to the normal
ModulePath. The idea behind this is that any output hardware specific
modules should have preference over the normal modules.
One use-case for this is the nvidia binary driver, this allows a
config snippet like this:
Section "OutputClass"
MatchDriver "nvidia"
Modulepath "/usr/lib64/nvidia/modules"
EndSection
To get the nvidia glx specific glx module loaded, but only when the
nvidia kernel driver is loaded.
Together with the glvnd work done recently, this allows the nouveau
+ mesa and nvidia-binary userspace stacks to co-exist on the same
system without any ldconfig / xorg.conf tweaking and the xserver will
automatically do the right thing depending on which kernel driver
(nouveau or nvidia) is loaded.

In InitOutput, if xf86HandleConfigFile returns CONFIG_NOFILE

later on.
xf86AutoConfig calls xf86OutputClassDriverList via the
call tree:
xf86AutoConfig =>
listPossibleVideoDrivers =>
xf86PlatformMatchDriver =>
xf86OutputClassDriverList
and xf86OutputClassDriverList attempts to traverse a linked list
that is a member of the XF86ConfigRec struct pointed to by the
global xf86configptr, which is NULL at this point because the
XF86ConfigRec struct is only allocated (by xf86readConfigFile)
AFTER the config file and directory have been successfully
opened; the CONFIG_NOFILE return from xf86HandleConfigFile
occurs BEFORE the call to xf86readConfigFile which allocates
the XF86ConfigRec struct.
Rx: In read.c (for symmetry with xf86freeConfig, which already
appears in this file), add a new function xf86allocateConfig
which tests the value of xf86configptr and, if it's NULL,
allocates the XF86ConfigRec struct and deposits the pointer
in xf86configptr. In xf86Parser.h, add a prototype for the
new xf86allocateConfig function.
Back in read.c, #include "xf86Config.h". In xf86readConfigFile,
change the open-code call to calloc to a call to the new

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

The new platform bus code and the old PCI bus code overlap. Platform bus
can handle any type of device, including PCI devices, whereas the PCI code
can only handle PCI devices. Some drivers only support the old style
PCI-probe methods, but the primary device detection code is server based,
not driver based; so we might end up with a primary device which only has
a PCI bus-capable driver, but was detected as primary by the platform
code, or the other way around.
(The above paragraph was shamelessly stolen from Hans de Goede, and
customized.)
The latter case applies to QEMU's virtio-gpu-pci device: it is detected as
a BUS_PCI primary device, but we actually probe it first (with the
modesetting driver) through xf86platformProbeDev(). The
xf86IsPrimaryPlatform() function doesn't recognize the device as primary
(it bails out as soon as it sees BUS_PCI); instead, we add the device as a
secondary graphics card under "autoAddGPU". In turn, the success of this
automatic probing-as-GPU prevents xf86CallDriverProbe() from proceeding to
the PCI probing.
The result is that the server exits with no primary devices detected.
Commit cf66471353 ("xfree86: use udev to provide device enumeration for
kms devices (v10)") added "cross-bus" matching to xf86IsPrimaryPci(). Port
that now to xf86IsPrimaryPlatform(), so that we can probe virtio-gpu-pci
as a primary card in platform bus code.

Xorg -configure relies on the bus implementation, e.g.
xf86pciBus.c to call xf86AddBusDeviceToConfigure(). The new
xf86platformBus code does not have support for this.
Almost all drivers support both the xf86platformBus and xf86pciBus
nowadays, and the generic xf86Bus xf86CallDriverProbe() function
prefers the new xf86platformBus probe method when available.
Since the platformBus paths do not call xf86AddBusDeviceToConfigure()
this results in Xorg -configure failing with the following error:
"No devices to configure. Configuration failed.".
Adding support for the xf86Configure code to xf86platformBus.c
is non trivial and since we advise users to normally run without
any Xorg.conf at all not worth the trouble.
However some users still want to use Xorg -configure to generate a
template config file, this commit implements a minimal fix to make
things work again for PCI devices by skipping the platform
probe method when xf86DoConfigure is set.
This has been tested on a system with integrated intel graphics,
with both the intel and modesetting drivers and restores Xorg -configure
functionality on both cases.

by one wrt the driver names and the last one contains NULL.

This is a problem for the libinput driver that uses the same context across
multiple devices. The driver may be halfway through setting up an input device
(and the only way to do so is to add it to libinput) when the input thread
comes in an reads events. This then causes mayhem when data is dereferenced
that hasn't been set up yet.
In my case the cause was the call to libinput_path_remove_device() inside
preinit racing with evdev_dispatch_device() handling of ENODEV. The sequence
was:
- thread 2 gets an event and calls evdev_dispatch_device()
- thread 1 calls libinput_path_remove_device() which sets the device->source
to NULL
- thread 2 reads from the fd, gets ENODEV and now removes the device->source,
dereferencing the null-pointer
This is the one I could reproduce the most, but there are other potential
pitfalls that affect any driver that uses the same fd for multiple devices.
