b5dffbbac1 xfree86: Add ModulePath support for OutputClass config Sections
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.

8b335d9068 Fix a segfault that occurs if xorg.conf.d is absent:
In InitOutput, if xf86HandleConfigFile returns CONFIG_NOFILE
(which it does if no config file or directory is present), the
autoconfig flag is set, causing xf86AutoConfig to be called
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
xf86allocateConfig function.

In xf86AutoConfig.c, add a call to the new xf86allocateConfig function
to the beginning of xf86AutoConfig to make sure the XF86ConfigRec struct
is allocated.

fc4fbe8224 xfree86: add NoMatchFoo directives for InputClass sections
InputClass sections use various MatchFoo directives to decide which device to
apply to. This usually works fine for specific snippets but has drawbacks for
snippets that apply more generally to a multitude of devices.

This patch adds a NoMatchFoo directive to negate a match, thus allowing
snippets that only apply if a given condition is not set. Specifically, this
allows for more flexible fallback driver matching, it is now possible to use a
snippet that says "assign driver foo, but only if driver bar wasn't already
assigned to it". For example:

Section "InputClass"
   Identifier "libinput for tablets"
   MatchIsTablet "true"
   NoMatchDriver "wacom"
   Driver "libinput"
EndSection

The above only assigns libinput to tablet devices if wacom isn't already
assigned to this device, making it possible to select a specific driver by
installing/uninstalling it.

dabf7c3590 libxf86config: Remove
The library used by the Xserver to read and parse the configuration file
could be built so that it culd be installed as a separate lib and used
by external programs.

Apparently there has not been any interest in this for quite a while as
this library has been broken for a long time now in the sense that it
was calling functions provided by the Xserver which were not implemented
for the external library.

Since this library is useless as it is anyway when built let's drop
support for it.

Section "Device"

EndSection

Section "Screen"

a270bb18ba xfree86: Introduce OutputClass configuration
The OutputClass section provides a way to match output devices to a set
of given attributes and configure them. For now, only matching by kernel
driver name is supported. This can be used to determine what DDX module
to load for non-PCI output devices. DDX modules can ship an xorg.conf.d
snippet (e.g. in /usr/share/X11/xorg.conf.d) that looks like this:

	Section "OutputClass"
	    Identifer "NVIDIA Tegra open-source driver"
	    MatchDriver "tegra"
	    Driver "opentegra"
	EndSection

This will cause any device that's driven by the kernel driver named
"tegra" to use the "opentegra" DDX module.

See the OUTPUTCLASS section in xorg.conf(5) for more details.

7070ebeeba xfree86: add new key MatchSeat to xorg.conf sections "Device", "Screen", and "ServerLayout"
This patch introduces a new key MatchSeat in xorg.conf (also applies to
any .conf file in xorg.conf.d). It will allow targeting a given
"Device", "Screen", and/or "ServerLayout" section to a particular
seat only (specified by option "-seat" in X server command line),
so that other seats won't be affected.

Without this patch, one needs to write a separate xorg.conf.custom
file and pass it to X server via "-config" option, if one wants that
these settings only apply for the right seat. However, in some cases,
this solution is undesirable or even impossible (e.g. when using GDM,
which doesn't allow X server command line customization).

Example file (/etc/X11/xorg.conf.d/seat1.conf), which would be ignored
by X server unless it was started with "-seat seat1" option:

Section "Device"
    Identifier "card0"
    Driver "nvidia"
    Option "NoLogo" "True"
    MatchSeat "seat1"
EndSection

	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

820d9040f5 xfree86: fix potential buffer overflow
The patch below fixes a potential buffer overflow in xf86addComment().
This occurs if  curlen > 0 && eol_seen == 0 && iscomment == 0 , as
follows from the code:

char *xf86addComment(char *cur, char *add)

<...>

        len = strlen(add);
        endnewline = add[len - 1] == '\n';
        len +=  1 + iscomment + (!hasnewline) + (!endnewline) + eol_seen;

        if ((str = realloc(cur, len + curlen)) == NULL)
                return cur;

        cur = str;

        if (eol_seen || (curlen && !hasnewline))
                cur[curlen++] = '\n';
        if (!iscomment)
                cur[curlen++] = '#';
        strcpy(cur + curlen, add);
        if (!endnewline)
                strcat(cur, "\n");

xfree86: Move definition of xf86OptionPtr into separate header file

The pile of spaghettis that is the xfree86 include dependencies make it
rather hard to have a single typedef somewhere that's not interfering with
everything else or drags in a whole bunch of other includes.

Move the xf86OptionRec and GenericListRec declarations into a separate
header.

c05c8640f1 xfree86: Allow "MatchLayout" statements in config files
Usage example (tested on a dual-seat PC):
Section "InputClass"
 	Identifier "keyboard-all"
 	MatchIsKeyboard "on"
 	MatchDevicePath "/dev/input/event*"
 	MatchLayout "!GeForce|!Matrox"
 	Driver "evdev"
 	Option "XkbLayout" "us"
 	Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

It disables auto keyboard configuration for layouts "GeForce" and "Matrox".
Note that "" in patterns means "no Layout sections found", e.g.
 	MatchLayout "GeForce|"
is "in layout GeForce or without explicit layout at all".

60801ff870 xfree86: Convert libxf86config to static libtool library
In order to use libxf86config in a shared library, all the code must be
compiled with -fPIC. Add proper PIC support for libxf86config by turning
it into a libtool library. However, since we don't want to guarantee API
or ABI stability, make sure it's only built static.
