[PATCH] SJA1000: ixxat_pci: fix the detection of the second SJA1000 chip
According to the SJA1000 data sheet, section 6.3.2, only the bits 0,5
and 7 of the control/mode register are defined after a reset. This
patch uses a proper mask before checking the value.

This patch allows pcmcia subsystem >= 2.6.28
The function pcmcia_loop_config is used. To support kernels < 2.6.28
the pcmcia_loop_config function is emulated (it does basically the same
as what I used to do, but seperates the code much cleaner) for these kernels.
This is definitely a change, but does not break on recent builds.
Additionally, in order to test the pcmcia access, the code needed to be
tested for 8bit softing pcmcia cards too. Historically, these cards did not
support shared irq's. But my current system, AMD64, does not provide exclusive
interrupts anymore. Therefore, the old 8bit cards are moved to have shared
irq's. The code did succeed in my elementary tests.

Changed comment line recognition:
Everything without a '(' at the beginning of an input line is treated as comment.
Changed buffer size to allow long comment lines & added overflow handling.
Added automatic extended frame format recognition.
Most SocketCAN userspace tools (like cansend) recognize the EFF by the
stringlength of the given CAN-ID: 3 -> SFF , 8 -> EFF.
This was missing in the candump filter definition and therefore the
values had to be specified with the CAN_EFF_FLAG set in the value, e.g. 92345678 for the extended CAN-ID 12345678 - this was not really nice.
Now the filtersets for extended frames can be specified as expected: 12345678:1FFFFFFF to filter for only 12345678 extended CAN-ID 000000AA:1FFFFFFF to filter for only AA extended CAN-ID.
