This fixes the valgrind integration with the new test drivers.

The same variable was used for return values from NiceSocket and
for the internal enum, but 0 and -1 have different meanings in both.

Various little things, none of which should make a functional difference.

It exits the loop immediately, so no point to set the variable.
And it makes the clang static analyzer happy.

It's now an array, not a pointer, so needs to test to emptyness.

It's a bugfix on the previous commit, 59ce41df

Consider that the answer is received when remote credentials
are set instead of when a remote candidate is set,
which could not happen or could cause more delay for the
connection establishment.

There was a confusion and it tested against a value not in the enum.

We don't have or call noreturn functions in practice and it makes
the stun test build fail on clang.

This makes clang happy.

clang on recent macOS seems to only emit a warning on unknown flags
which makes this test fail and then when using Werror, it makes the
compiler test fail too.

It's only nonce level randomness, not long term key level.

Using a IPv6 local address to connect to a IPv4 relay just creates an
extra discovery attempt that will not provide something useful.

This commit fixes another place of TURN discovery creation which was
omitted in fc0d3744

down up to ~15 seconds from candidate gathering phase, making it almost

agent_recv_message_unlocked() always receives a single message and
returns a RecvStatus code.

Avoid weird debugs like "received -1 valid messages" (when retval is
RECV_WOULD_BLOCK) and print the message only when something was actually
received.

Previously, a custom Mersenne Twister PRNG was used, which is not
securely random. In addition, its seeding fell back to wall-clock time,
which is typically predictable.

This uses libgcrypt on Linux but retains the Windows code which uses the

There should never be a problem with alignment at runtime, since we’re
casting the sockaddr to sockaddr_in or sockaddr_in6 based on its
declared sa_family — anything declared as AF_INET6 should have been
allocated as a sockaddr_in6, and hence have appropriate alignment (same
for AF_INET).

This fixes a compiler warning on ARM and other alignment-sensitive
architectures.

Client should stop sending connectivity checks with legacy FINGERPRINT
when it receives a conncheck message containing IMPLEMENTATION-VERSION
attribute.

In order to preserve compatibility with clients which use custom CRC
lookup table from [MS-ICE2], whenever a connectivity check request or
reply is sent, an additional message is sent along. These two messages
differ only in FINGERPRINT attribute - one uses regular CRC lookup table
for calculation, the other uses the modified table.

When a message is received and FINGERPRINT doesn't pass validation using
regular CRC table, the receiver also tries to verify using the modified
table.

[MS-ICE2] 3.1.4.8.2 describes this procedure.

The commit fixes compatibility with older MSOC and Lync clients.
