Pedro Monreal Gonzalez 32ced036f1 Accepting request 786956 from home:vitezslav_cizek:branches:security:tls 
- Update to 1.1.1e
  * Properly detect EOF while reading in libssl. Previously if we hit an EOF
    while reading in libssl then we would report an error back to the
    application (SSL_ERROR_SYSCALL) but errno would be 0. We now add
    an error to the stack (which means we instead return SSL_ERROR_SSL) and
    therefore give a hint as to what went wrong.
  * Check that ed25519 and ed448 are allowed by the security level. Previously
    signature algorithms not using an MD were not being checked that they were
    allowed by the security level.
  * Fixed SSL_get_servername() behaviour. The behaviour of SSL_get_servername()
    was not quite right. The behaviour was not consistent between resumption
    and normal handshakes, and also not quite consistent with historical
    behaviour. The behaviour in various scenarios has been clarified and
    it has been updated to make it match historical behaviour as closely as
    possible.
  * Corrected the documentation of the return values from the EVP_DigestSign*
    set of functions.  The documentation mentioned negative values for some
    errors, but this was never the case, so the mention of negative values
    was removed.
  * Added a new method to gather entropy on VMS, based on SYS$GET_ENTROPY.
    The presence of this system service is determined at run-time.
  * Added newline escaping functionality to a filename when using openssl dgst.
    This output format is to replicate the output format found in the '*sum'
    checksum programs. This aims to preserve backward compatibility.
  * Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just
    the first value.
- Update bunch of patches as the internal crypto headers got reorganized
- drop openssl-1_1-CVE-2019-1551.patch (upstream)

- openssl dgst: default to SHA256 only when called without a digest,
