ra loops forever on cisco netflow file

[dbrumley at puttputt.Stanford.EDU]

>Description:
  ra() never exits when reading cisco netflow log files.

>How-To-Repeat:

  when reading a cisco log file, ra keeps looping.  I think this is
because the same code used to read from a udp socket is used to read
from a file.  However, they are different, as the read from udp should
continue until the user aborts (through control-c or some byte count),
while reading from a file should exit when EOF is reached.

Here's the code area:
(gdb) bt
#0  0xff2171d4 in _read () from /usr/lib/libc.so.1
#1  0x1be68 in ArgusReadCiscoStreamSocket (input=0x1214d0)
     at ./argus_parse.c:1479
#2  0x1c444 in ArgusReadStream () at ./argus_parse.c:1640
#3  0x19458 in main (argc=4, argv=0xffbefa6c) at ./argus_parse.c:494
(gdb)

read() just blocks.

>Fix:
  I don't know yet :)
