wmediumd multi-medium implementation

[onurklngc]

Changes required to use muti-medium feature coming with ramonfontes/wmediumd/pull/9

Initial multi-medium assignment can be performed with net.setInitialMediums((("sta1-wlan0", sta2, ap1)) which adds multimedium array data to wmediumd config file. Elements can either be the name of the interface or the station/AP object itself.

Medium IDs can be assigned at runtime as follows:

# Adding ap3's first interface to medium #3
ap3.setMediumId(3, intf=None)
# Adding sta6-wlan0 interface to medium #3
sta6.getNameToWintf("sta6-wlan0").setMediumId(3)

Includes example file named multimedium.py

This is a really interesting feature. We are discussing some improvements at ramonfontes/wmediumd#9

Hello,

Have you thoroughly tested this solution? Has it been working well?

Hello Dr. Fontes,

Yes, I have tested it.

Station - AP connections are automatically detected by default. It can be disabled via the wmediumd config file(related check)

I can also add a parameter for user to decide if s/he want to enable/disable it from Mininet-Wifi by inserting related line to the config file on startup.
