* Refactor the command line plotting & management code into a package
* Refactor the stats-gathering code into a new package
* Switch to build flags for non-portable packages/code
Initial version of -r for TCP bandwidth tests + few other enhancements:
- Add timestamp in log messages.
- Handle the case where timer tick is delayed on client side. Server side still
needs work.
- Use high value of GOMAXPROCS to fix starvation of some goroutines.
- Support option to disable per connection statistics. If large number
of sessions are used, then per connection stats were making it hard
to read the results on console.
- Synchronize stats timer between client/server. This makes server and
client print similar test results. Earlier, under varying TCP throuhgput,
results in server and client side were different due to different time
periods for calculating throughput.
