Sort the RPC statistics in descending order by operation count, so
that the most frequently executed operation appears at the top of
the listing (a la `top`).

When running mountstats under "watch," occassionally the output
shows "close failed in file object desctructor: sys.excepthook is
missing" and the data display is messed up. This seems to be a
common problem when Python script output is piped to another
program.
Ensure stdout/stderr is completely flushed before mountstats exits,
and add an IOError exception handler to catch these exceptions
gracefully.
Solution suggested by: http://bugs.python.org/issue11380

Use install -m instead of--mode for better compatibility.
E.g. busybox's install doesn't support the long option.

Commit b703eabe converted mountstats to using python3's print()
function, but this doesn't work in python2.x without
importing the print function from __future__.

mountstats depend on all devices entries in /proc/self/mountstats
to start with the word 'device'. With 3.1 kernels, NFS entries
start with the actual device (i.e. server:/export) not
the word 'device'. This change confused mountstats parsing.

License texts contain multiple address for FSF, some wrong.
So update them and replace COPYING file with
http://www.gnu.org/licenses/gpl-2.0.txt
which has a few changes to preamble and commentary.
Also remove extra COPYING file from utils/statd/

client performance information from /proc/self/mountstats.
Note that if mountstats is named 'ms-nfsstat' or 'ms-iostat' it offers
slightly different functionality. It needs two man pages and the install
script should provide both commands by installing the script and providing the
other command via a symlink.
