Sukchan Lee da5d424ed9 [MME] Incorrect behavior of SGsAP+Dedicated-Bearer (#3072) 
First of all, it crashes when creating a Dedicated Bearer
on the default Session that is created for the first time.
This behavior should be possible, so the related ASSERT is removed.

Next, the InitialContextRequest is modified
during the Attach Request to include the first Bearer.

Finally, there was an issue where trying to create a Dedicated Bearer
with SGsAP enabled resulted in an InitialContextSetupRequest message
with a PTI of zero. This is because MME initializes the PTI to 0
upon receiving the Create Bearer Request while processing SGsAP.

All of these issues has been fixed.

Rename GTPv2C specifics to gtp2 prefix (#1485) 
In the past only GTPv2C was supported, and had the "gtp" generic prefix.
Later on, GTPv1C support was added, and "gtp1" prefix was used.
Let's move GTPv2C specific bits to have "gtp2" prefix too, and leave
"gtp" prefix for generic stuff among different GTP versions.
