fix parameters and script for testbed - no calibrate stage
ping SA is possible in testbed; change Q tc bw
poll_freq bug
debug: tcpdump on A runs same time as S or later?
problem in passive() killall doesn't run?
hopefully tcpdump timing issues are fixed now

TODO: remove before and after tcpdumps;
TODO: make similar changes to master branch (poll_freq and tcpdump)
TODO: maybe remove scheduler and have simple num_of_runs with the calibrate function too
collect data for 10 test runs
try without states - only one huge tcpdump + radiotap
appropriate changes to server
Merge branch 'testbed' of github.com:shahifaqeer/browserlab-linktest into testbed

server side awesomeness
added time infor to debug wait statements
somehow radiotap and tcpdump seem like blocking commands

the next command like fping all or experiment only passes after 'timeout' has expired.
this shouldn't really be happening. So for the moment I've replaced tcpdump(timeout)
with a smaller value (like 10 sec)
rename pcap files without underscore
calibrate on for real and off for testbed
fix typo for real measurements
Merge branch 'testbed' of github.com:shahifaqeer/browserlab-linktest
fix typo client address
changes for testbed measurements
disable udp measurements temporarily
fix conflicts
