[SMF] Fix potential null pointer dereference ( #1324 )
...
* [SMF] Fix potential null pointer dereference
Pointer "sess" was first dereferenced and later on checked for nullness.
This is clearly wrong. Rearrange the code path to make sure the check is
done first, then dereferenced.
* gitignore: Add subprojects/libtins
* cosmetic: Fix whitespace

[ #568 ] Add GTP-U Error Indication Handling
...
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.
Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.
