From ce7de0261f0c1f1640da5673dd24939a37e33bd9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] libcrypto-compat: add extra functions
Changed the define to compare OPENSSL_API_COMPAT instead of version as
OpenSSL can be compiled in different ways. One is to disable all
deprecated APIs.
Added extra functions. The next commit will switch to them.

Subject: [PATCH 2/2] libcrypto: remove deprecated API usage
EVP_CIPHER_CTX_init was replaced with _reset.
Removed EVP_CIPHER_CTX_cleanup. The successive _free call handles that.
Removed old SSLeay function usage.

Subject: [PATCH] channels: Avoid returning SSH_AGAIN from
ssh_channel_poll_timeout()
This addresses a regression introduced in 3bad0607, partially fixed in 022409e9,
but the function was still able to return SSH_AGAIN, which was not expected by
callers.
Based on discussion in [1] and [2]
