Add RINGBUFFER_WARN_NUM_FILES and use it to print a warning. Print
warnings when we change the number of ringbuffer files.

as an argument, rather than keeping the count to themselves, so the
count kept by the capturing program can be updated correctly - including
getting reset when files are switched. Fixes bug 895.

bypass Wiretap; that means we don't have to run the packet through
wtap_process_pcap_packet() and then undo that conversion in Wiretap if
we're just going to write it out, shortening the code path.

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Almost completely rewritten in order to:
- be able to use a unlimited number of ringbuffer files
0 specified with -b argument or in the GUI, means that the number of file
is unlimited.
else the maximum number of ring buffer files is arbitrarily set to 1024.
- close the current file and open (truncating it) the next file at switch
- set the final file name once open (or reopen)
- avoid the deletion of files that could not be truncated (can't arise now)
and do not erase empty files
The idea behind that is to remove the limitation of the maximum # of
ringbuffer files being less than the maximum # of open fd per process
and to be able to reduce the amount of virtual memory usage (having only
one file open at most) or the amount of file system usage (by truncating
the files at switch and not the capture stop, and by closing them which
makes possible their move or deletion after a switch).

files to get that big.
From Thomas Wittwer and Matthias Nyffenegger:
Support for "ring buffer mode", wherein there's a ring buffer of N
capture files; as each capture file reaches its maximum size (the ring
buffer works only with a maximum capture file size specified), Ethereal
rolls over to the next capture file in the ring buffer, replacing
whatever packets might be in it with new packets.
