On a setup, length of cellGroupConfig was > 255.

Using uint8_t to store the length is thus wrong
and gives a bad encoding of the cellGroupConfig.

So let's use uint32_t to store length instead of uint8_t.

remove eNB threads for RRC and MAC, MAC thread was only for DRX config (useless) and RRC thread has many race conditions with MAC+PHY
