wmifs: Add BUFFER_SIZE constant.

Patch by Stephen Pitts <smpitts@midsouth.rr.com>.  First appeared in Debian
package version 1.3b1-4.

From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=41746:

wmifs started crashing on startup on my system,
so I grabbed the source, added -g to the
Makefile, and ran it through gdb.
(Wow, the wonders of Open Source!!).

I found out that it has the hard-coded assumption
that a line in  /proc/net/dev will be no longer
than 128 bytes. Since my ethernet card has over
1 GB in traffic , my eth0 line was 129 bytes long.
I added a new constant, BUFFER_SIZE, that
determines the size of the buffer used for fgets.

Right now, its at 512 bytes, so that gives it
a large margin of error, until we have petabyte
Ethernet! The patch is attached.

wmifs: Prevent speedy scrolling problem.

Patch by Barak Pearlmutter <bap@cs.unm.edu>.  First appeared in Debian package
version 1.3b1-6.

From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=83003:
On my laptop, following a suspend, wmifs scrolls like nuts for a long
time.  The scroll speed looks the same as for a wmifs that is paused
for a while using C-z.

Here is a patch that prevents this speedy scrolling problem.  I also
got rid of a couple unnecessary compiler warnings.
wmifs: Prevent crash when too many devices.

Patch by Chris Hanson <cph@martigny.ai.mit.edu>.  First appeared in Debian
package 1.3b1-6.

From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=39922:
wmifs crashes with a cryptic X error message when there are more than
4 net devices.  This occurs for me because I install vmware, which
installs 4 network devices for its bridging hack.

The bug is a loop that fills a fixed-length array, but doesn't stop
when the array is full.  The fix is to add a conditional break to the
loop.  A patch appears below.

I made two additional changes: (1) increased the size of the array,
and (2) changed a name comparison to compare all of the characters of
the name, rather than just the visible characters, since there may be
multiple net devices with the same first 4 characters (vmware does
this, too).
