sgsn/test: Add test case for unexpected Detach Accepts
The commit "sgsn: Don't send XID reset after Detach Accept" fixed the
SGSN to not respond to a Detach Accept message when there is no MM
context.
This patch adds a test case to verify, that there is really no
message sent in that case.
The test fails when the commit mentioned aboved is reverted.

sgsn/test: Don't rely on the actual PRNG sequence
Currently the expected P-TMSI generated by the SGSN is hard-coded
into the test. This adds a dependency on the implementation of rand()
and thus the libc used. This breaks the test e.g. on FreeBSD.
This patch modifies test_gmm_attach() to srand(1) first, generate the
P-TMSI, and finally srand(1) again before starting the test.

gbproxy: Reset TLLIs when the link_info is found by IMSI/P-TMSI
Currently when the MS does a re-attach without doing a proper detach
first, the gbproxy uses the old local TLLI if patching and the keep
mode are enabled. This leads to a failing attachment procedure when
TLLI patching is also enabled.
This patch changes gbproxy_update_link_state_ul to reset all TLLIs
within the link_info if the message contains an unknown TLLI and an
MI. This is generally the case with Attach Request messages.
The gbproxy_get_link_info_ul gets an additional tlli_is_valid
output parameter that is set, when a TLLI was present and found.
This flag is then used instead of checking tlli.current == 0 to
set TLLI/P-TMSI e.g. Attach Requests when a link_info was already
present for the P-TMSI/IMSI used in such a request.
Ticket: OW#1324
