main.lua: Replace tabs with spaces and fix identation on main().
main.lua: Add command-line argument for snabbswitch to support '-jv'

 * This causes luajit to shows verbose information about the progress
   of the JIT compiler. It logs the information to 'file'.

 * You can use "/dev/stderr", "/dev/stdout" or "-" as file names if
   you want the information to be printed on the screen.

iperf now runs in bidirectional mode.
iperf test is now run in the tunneled mode.
iperf test is now run both with and without jumbo frames.
Avoid division by zero in calculation of loss rate

If there are no packets sent, print loss rate '0' instead of 'NaN'.
Iterate timers list using an index instead or pairs

* Timers list is an array (of ticks), so it can be iterated using an
index. Iterating an array using an index is faster than using pairs.
* Benchmark selftest execution time. The test is now 44% faster.
* Some code refactoring.
Use index instead of pairs in method 'generate' in Fuzz apps.

* src/apps/fuzz/ethernet.lua: Iterate with index instead of pairs.
* src/apps/fuzz/ipv4.lua: Iterate with index instead of pairs.
* src/apps/fuzz/ipv6.lua: Iterate with index instead of pairs.
* src/apps/fuzz/matcher.lua: Use ipairs instead of pairs.
* src/apps/fuzz/tcp.lua: Iterate with index instead of pairs.
* src/apps/fuzz/udp.lua: Iterate with index instead of pairs.
* src/core/lib.lua: Add method for copying arrays.
