Subject: [PATCH] dataxfer.c: fix possible buffer overruns caused by
gai_strerror
This fixes a possible buffer overrun that could occur due to
gai_strerror() returning a string which is longer than the portbuff
array, i.e. longer than 32 byte.

Subject: [PATCH] dataxfer.c: truncate error message to fit the column width
gai_strerror() could return a string which is longer than our current
column width of "Remote address". To make the output nice again,
truncate the error string in this case.

Subject: [PATCH] dataxfer.c: adjust "Remote address" column width
In case we are connected to an IPv6 address the current column width
is too small to take the complete address and port number so adjust it.

Subject: [PATCH] dataxfer.c: in case port is not connected display this
directly
In this case we don't bother to call into getnameinfo but show
directly "unconnected", this prevents showing an error message.
