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

bca7083e82 avoid integer overflow in and around smartlist_ensure_capacity.
This closes bug 18162; bugfix on a45b131590, which fixed a related
issue long ago.

In addition to the #18162 issues, this fixes a signed integer overflow
in smarltist_add_all(), which is probably not so great either.

b0867fec96 Fix a compilation warning introduced by clang 3.6
There was a dead check when we made sure that an array member of a
struct was non-NULL.  Tor has been doing this check since at least
0.2.3, maybe earlier.

Fixes bug 17781.
