Primitive encodings shouldn't use indefinite length constructed
form.

PR#2438 (partial).
(cherry picked from commit 398e99fe)

IN parameter.

Under the old docs, the only thing stated was "at most
EVP_PKEY_size(pkey) bytes will be written". It was kind of misleading
since it appears EVP_PKEY_size(pkey) WILL be written regardless of the
signature's buffer size.

In the ssl_cipher_get_evp() function, fix off-by-one errors in index validation before accessing arrays.

Bug discovered and fixed by Miod Vallat from the OpenBSD team.

PR#3375

This reverts commit 7e98378d.

Incorrect attribution.

Allow CCS after finished has been sent by client: at this point
keys have been correctly set up so it is OK to accept CCS from
server. Without this renegotiation can sometimes fail.

PR#3400
(cherry picked from commit 99cd6a91fcb0931feaebbb4832681d40a66fad41)

Based on an original patch by Joel Sing (OpenBSD) who also originally identified the issue.

(cherry picked from commit 7a9d59c1)

Fix strength_bits to 112 for 3DES.

Because of a missing include <fcntl.h> we don't have O_CREATE and don't create
the file with open() using mode 0600 but fall back to using fopen() with the
default umask followed by a chmod().

Problem found by Jakub Wilk <jwilk@debian.org>.

If application uses tls_session_secret_cb for session resumption
set the CCS_OK flag.
