add some of the more useful features from nuttcp

[GoogleCodeExporter]

Besides 'burst mode', which is already entered as another issue, I find the 
following nuttcp command line options quite useful:

ability to set the server window size from the client:
    -ws##   server receive|transmit window size in KB (or (m|M)B or (g|G)B)

ability to label output; useful when launching multiple tests from the same 
window.
    -Ixxx   identifier for nuttcp output (max of 40 characters)

ability to increase process priority:
    -xP##   set nuttcp process priority (must be root)

Multilink aggregation options:
         nuttcp [-options] -N##  [ctl_addr]/host1/host2/.../host##  

ability to specify which core to use:
        -xcN/N    specify core for the sender/receiver

I do not find any of the command line flag names very intuitive, so they can 
all be changed if desired.

These are now complete, or in other issues. Closing.
