- update maximum PDU (buffer) size to 64kByte buffer
- support setting of N_As (frame_txtime) to zero

if_nametoindex() returns zero and a specific errno in the case the network
interface does not exist. The missing check leads to the use of the 'any'
CAN device but leaves the user alone as the user gets no error message.

replaced strcpy(if_name, argv[x]) + ioctl by if_idx = if_nametoindex(argv[x])
to avoid overflows caused by long user input.

Allow to specify the TX and RX padding content separately.
Due to the optional values it is possible to provide either TX or RX values
which enables and set the given values.
-p 55:AA => TX padding 0x55, RX padding 0xAA
-p 55 => TX padding 0x55
-p 55: => TX padding 0x55
-p :AA => RX padding 0xAA
Additionally the comment for the -P <mode> option was updated to point out the
checking mode of the padding in the received PDUs (rx padding).

Enable to pass the optional second extended address with the '-x' option and
do not pollute the command line options with just another '-X' option.

As requested by Laurent Vaudoit the extended address can be different in the
tx and he rx path:
(..) how can i have a segmented transfer like this:
0x6a7 0x55 0x10 0x08 ........
0x687 0xAA 0x30 0x00 0x00
0x6a7 0x55 0x21 .....
The connection i need is between two ECU, using IDs 0x6a7/687 and one has
adress extension 0x55, the other 0xAA (this adressing method is used on some
FIAT ECUs for example).

misbehave for regression tests.
CAN_ISOTP_TX_STMIN:
Set a value in nano secs that's used as minimum CF gap by the sender.
This value is used instead of the value provided by the receiver inside the FC.
CAN_ISOTP_RX_STMIN:
Ignores received CF frames which timestamps differ less than this value in nano
secs. This is used to test the receivers misbehaviour when the receiver
provides a lower stmin value that he's able to cope with. Received CF frames
are silently dropped when they come faster than specified by this value.
