56a7c5bc15 TROVE-2017-005: Fix assertion failure in connection_edge_process_relay_cell
On an hidden service rendezvous circuit, a BEGIN_DIR could be sent
(maliciously) which would trigger a tor_assert() because
connection_edge_process_relay_cell() thought that the circuit is an
or_circuit_t but is an origin circuit in reality.

Fixes #22494

194e31057f Avoid integer underflow in tor_version_compare.
Fix for TROVE-2017-001 and bug 21278.

(Note: Instead of handling signed ints "correctly", we keep the old
behavior, except for the part where we would crash with -ftrapv.)

6cb8c0fd4e Refine the memwipe() arguments check for 18089 a little more.
We still silently ignore
     memwipe(NULL, ch, 0);
and
     memwipe(ptr, ch, 0);  /* for ptr != NULL */

But we now assert on:
     memwipe(NULL, ch, 30);

053e11f397 Fix out-of-bounds read in INTRODUCE2 client auth
The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.

Fixed by checking auth_len before comparing the descriptor cookie
against known clients.

Fixes #15823; bugfix on 0.2.1.6-alpha.

d978216dea Fix parsing bug with unecognized token at EOS
In get_token(), we could read one byte past the end of the
region. This is only a big problem in the case where the region
itself is (a) potentially hostile, and (b) not explicitly
nul-terminated.

This patch fixes the underlying bug, and also makes sure that the
one remaining case of not-NUL-terminated potentially hostile data
gets NUL-terminated.

Fix for bug 21018, TROVE-2016-12-002, and CVE-2016-1254
