c8024b633e Revert "Try using SSL_get_ciphers in place of session->ciphers" 
This reverts commit 67964cfa78.

It was the cause of #16153, and was not in any released Tor.  We need
a better solution for getting session->ciphers.

452cebc4a4 Remove support for OpenSSL without ECC. 
As OpenSSL >= 1.0.0 is now required, ECDHE is now mandatory.  The group
has to be validated at runtime, because of RedHat lawyers (P224 support
is entirely missing in the OpenSSL RPM, but P256 is present and is the
default).

Resolves ticket #16140.

f8f407d66a Now that OpenSSL 0.9.8 is dead, crypto_seed_rng() needs no args 
It needed an argument before because it wasn't safe to call
RAND_poll() on openssl 0.9.8c if you had already opened more fds
than would fit in fd_set.

67964cfa78 Try using SSL_get_ciphers in place of session->ciphers 
This should help openssl 1.1.  On pre-1.1, we double-check that these
two methods give us the same list, since the underlying code is awfully
hairy.

2f7c9b6ecb Tweak rectify_client_ciphers to work with openssl 1.1 
The key here is to never touch ssl->cipher_list directly, but only
via SSL_get_ciphers().  But it's not so simple.

See, if there is no specialized cipher_list on the SSL object,
SSL_get_ciphers returns the cipher_list on the SSL_CTX.  But we sure
don't want to modify that one!  So we need to use
SSL_set_cipher_list first to make sure that we really have a cipher
list on the SSL object.

712bf06978 Add support for 'HiddenServiceMaxStream' to 'ADD_ONION'. 
Done as a separate commit to ease backporting the tunables to 0.2.6.x.

db7bde08be Add "HiddenServiceMaxStreams" as a per-HS tunable. 
When set, this limits the maximum number of simultaneous streams per
rendezvous circuit on the server side of a HS, with further RELAY_BEGIN
cells being silently ignored.

This can be modified via "HiddenServiceMaxStreamsCloseCircuit", which
if set will cause offending rendezvous circuits to be torn down instead.

Addresses part of #16052.

6f9e90101e Fix crash on HUP with mixed ephemeral services 
Ephemeral services will be listed in rend_services_list at the end of
rend_config_services, so it must check whether directory is non-NULL
before comparing.

This crash happens when reloading config on a tor with mixed configured
and ephemeral services.

Fixes bug #16060. Bugfix on 0.2.7.1-alpha.

you have openssl 1.1, you won't even need it.

53a347592a ERR_remove_state() is deprecated since OpenSSL 1.0.0. 
OpenSSL 1.1.0 must be built with "enable-deprecated", and compiled with
`OPENSSL_USE_DEPRECATED` for this to work, so instead, use the newer
routine as appropriate.
