Since there was an ABI break and linking twice against libudev.so.0 and
libudev.so.1 causes the application to quickly crash, we first check if
the application is currently linked against libudev before dlopening a
local handle. However for backwards/forwards compatability, we need to
inspect the application for current linkage against all known versions
first. Not doing so causes a crash when both libraries are present and
so mesa chooses libudev.so.1 but the application was linked against
libudev.so.0.

DRI_PRIME is not very handy, because you have to launch the executable
with it set, which is not always easy to do.
By using drirc, the user specifies the target executable
and the device to use. After that the program will be launched everytime
on the target device.
For example if .drirc contains:
<driconf>
<device driver="loader">
<application name="Glmark2" executable="glmark2">
<option name="device_id" value="pci-0000_01_00_0" />
</application>
</device>
</driconf>
Then glmark2 will use if possible the render-node of
ID_PATH_TAG pci-0000_01_00_0.

v2: Fix the leak of device_name
v3: Rebased
It enables to use the DRI_PRIME env var to specify
which gpu to use.
Two syntax are supported:
If DRI_PRIME is 1 it means: take any other gpu than the default one.
If DRI_PRIME is the ID_PATH_TAG of a device: choose this device if
possible.
The ID_PATH_TAG is a tag filled by udev.
You can check it with 'udevadm info' on the device node.
For example it can be "pci-0000_01_00_0".
Render-nodes need to be enabled to choose another gpu,
and they need to have the ID_PATH_TAG advertised.
It is possible for not very recent udev that the tag
is not advertised for render-nodes, then
ones need to add a file containing:
SUBSYSTEM=="drm", IMPORT{builtin}="path_id"
