Added hasErrorStateIndicator and setErrorStateIndicator to QCanBusFrame.

* Setting QCanBusFrame::setErrorStateIndicator(true)
  also sets QCanBusFrame::setFlexibleDataRateFormat(true)

* Setting QCanBusFrame::setFlexibleDataRateFormat(false)
  also sets QCanBusFrame::setErrorStateIndicator(false)

[ChangeLog][QCanBusFrame] Added error state indicator flag
to QCanBusFrame and set it appropriate receiving CAN FD
frames with the SocketCAN plugin. Setting this flag for
testing purposes is also possible.

QCanBusFrame:

Added hasBitrateSwitch and setBitrateSwitch to QCanBusFrame
and therefore, increased the QCanBusFrame version number.

* Setting QCanBusFrame::setBitrateSwitch(true)
  also sets QCanBusFrame::setFlexibleDataRateFormat(true)

* Setting QCanBusFrame::setFlexibleDataRateFormat(false)
  also sets QCanBusFrame::setBitrateSwitch(false)

QCanBusDevice:

Reference implementation and documentation are done for
the SocketCAN plugin. The CAN Example allows to send
frames with Bitrate Switch enabled and visualize received
frames with Bitrate Switch set.

Unfortunately, the SocketCAN plugin does not allow to change
any bitrate yet, so the newly added data bitrate selection
box in ConnectDialog seems a bit useless. This box is
however needed once other plugins become CAN FD capable and
implement bitrate switching.

[ChangeLog][QCanBusFrame] Introduced flag to allow data
bitrate switching for CAN FD frames. Reference
implementation is done for the SocketCAN plugin.

Returns:
* a list of available devices for the chosen plugin
* if the device is virtual
* if the device is CAN FD capable

Use this list in the CAN Example for interface selection.

If information about virtual channels or CAN FD capabability is not
available, false is returned.

For SocketCAN, PeakCAN, VectorCAN and SystecCAN, the implementation is
completed. TinyCAN only return the list of possible interfaces for now.
This is can be changed later, but needs quite some refactoring of the
TinyCAN plugin.

[ChangeLog][QtCanBus] Added the new class QCanBusDeviceInfo
for enumeration of available CAN interfaces and more information
about them.

section 6.5.3:

  A device may enter the "bus-off" state if too many errors occurred on
  the CAN bus. Then no more messages are received or sent. An automatic
  bus-off recovery can be enabled by setting the "restart-ms" to a
  non-zero value, e.g.:

    $ ip link set canX type can restart-ms 100

The first stable API release is Qt 5.8. It makes no sense to document
the changes before 5.8. Furthermore the meaning of \since 5.8 before this
tag was rather unknown. It could have meant the function was changed or added.
This double meaning disappears once a compatibility statement is in place.
