sgsnemu: delete pdp context - teardown must be before NSAPI
...
in front of Cisco and Alcatel GGSN's, we meet the following error :
5 packets transmitted
Disconnecting PDP context #0
openggsn[24940]: gtp.c: 2417: Unexpected cause value received: 193. Packet from 172.29.5.130:2123, length: 14, content: 32 15 00 06 00 00 00 01 04 02 00 00 01 c1
it is because in the sgsnemu requests packet, the teardown field is after the NSAPI field :

[SECURITY] Fix GTPIE parsing DoS
...
This is taken from http://sourceforge.net/tracker/index.php?func=detail&aid=1811511&group_id=68956&atid=522957 and http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg402969.html and addresses a DoS:
The problem lies in the parsing of information elements in GTP messages, which
is implemented in the gtpie_decaps function of gtp/gtpie.c file.
The implementation has a bug that does not check if there are too many
information elements in the message thus causing the software to loop
infinitely in the while-loop.
In addition, handling routine for the error situation had to be implemented
outside the while-loop.

remove autotools-generated files
...
All those will be re-generated by "autoreconf -i" anyway, so
there's no point in keeping them in the repository.
Also, the 'bootstrap' script is no longer working with recent
autotools versions anyway.
