When sniffing CAN FD isotp traffic both listen-only sockets have to be
switched to process CAN FD frames.

If j1939spy is started with the verbose option "-v" or "--verbose", it
will print the error "j1939spy: listening: Success" and exit. Remove
this option altogether.

We don't need to block any signals, so a select() is sufficient. This
also fixes the problem that sigmask is uninitialized and may block the
sig ARLM, which make canbusload hang until a CAN frame is recieved.

If CAN_ERR_CNT is set, the snprintf_can_error_frame() bails out, as it
cannot decode CAN_ERR_CNT.

In 913311fc15 ("can-calc-bit-timing: add support to decode user
supplied bit timing parameters") support to decide user supplied bit
timing parameters was added. However, it was forgotten to add --tq to
the help text.
Add help text for the --tq paramter.

Commit 0be066bee6 ("cansequence: main(): allow to bind on "any"
interface") converted from SIOCGIFINDEX ioctl() to if_nametoindex()
and adjusted the error message, but forgot the "()" after the function
name, which is used in the rest of the error messages in this file.
Add the missing "()".

In commit 9567230494 ("cansequence: print out dropped packages by
socket counter"), the read() syscall was replaced by recvmsg(). Adjust
error message accordingly.
Fixes: 9567230494 ("cansequence: print out dropped packages by socket counter")
It is not implemented and not supported by any of the can-utils, so
remove it.

The check has only been applied after the first CAN frame has been read
and evaluated. This lead to an unintended sending of a single handcrafted
frame with a following (intended) failure at the second frame.
Apply the check also for the very first CAN frame that is processed.
