db1664e593 Improve comment about why we disable TLS compression.
Closes bug 22964.  Based on Teor's replacement there, but tries
to put the comment in a more logical place, and explain why we're
actually disabling compression in the first place.

50facb40bb On v3 link handshake, send the correct link certificate
Previously we'd send the _current_ link certificate, which would
cause a handshaking failure when the TLS context rotated.

6fcaf83c98 Cleanup MOCK_IMPL (etc) to be findable with etags
A fair number of our mock_impl declarations were messed up so that
even our special AM_ETAGSFLAGS couldn't find them.

This should be a whitespace-only patch.

a8b9aba912 Change many tortls.h declarations of private APIs to use structs
This change makes it so those those APIs will not require prior
inclusion of openssl headers.  I've left some APIs alone-- those
will change to be extra-private.

f6e5a658df Revise the logic for picking the start time for link certs
Since 0.2.4.11-alpha (in 0196647970) we've tried to randomize
the start time to up to some time in the past.  But unfortunately we
allowed the start time to be in the future as well, which isn't
really legit.

The new behavior lets the start time be be up to
MAX(cert_lifetime-2days, 0) in the past, but never in the future.

Fixes bug 21420; bugfix on 0.2.4.11-alpha.

f156156d56 Audit use of tor_tls_cert_get_key().
This function is allowed to return NULL if the certified key isn't
RSA. But in a couple of places we were treating this as a bug or
internal error, and in one other place we weren't checking for it at
all!

Caught by Isis during code review for #15055.  The serious bug was
only on the 15055 branch, thank goodness.

70e7d28b3e Generate our x509 certificates using sha256, not sha1.
All supported Tors (0.2.4+) require versions of openssl that can
handle this.

Now that our link certificates are RSA2048, this might actually help
vs fingerprinting a little.

b004ff45d7 New authentication types to use RFC5705.
See proposal 244.  This feature lets us stop looking at the internals
of SSL objects, *and* should let us port better to more SSL libraries,

69dce09031 Do not call tor_tls_server_info_callback(NULL) from tests.
This isn't valid behavior, and it causes a crash when you run
the unit tests at --debug.

6ddef1f7e0 Bug 19406: OpenSSL removed SSL_R_RECORD_TOO_LARGE in 1.1.0.
This is a logging onlu change, we were suppressing the severity down to
INFO when it occured (treating it as "Mostly harmless").  Now it is no
more.

b563a3a09d Bug 19406: OpenSSL made RSA and DH opaque in 1.1.0.
There's accessors to get at things, but it ends up being rather
cumbersome.  The only place where behavior should change is that the
code will fail instead of attempting to generate a new DH key if our
internal sanity check fails.

Like the previous commit, this probably breaks snapshots prior to pre5.

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.
