SSL: logging levels of errors observed with BoringSSL.

Browse Source 
As tested with tlsfuzzer with BoringSSL, the following errors are
certainly client-related:

SSL_do_handshake() failed (SSL: error:10000066:SSL routines:OPENSSL_internal:BAD_ALERT)
SSL_do_handshake() failed (SSL: error:10000089:SSL routines:OPENSSL_internal:DECODE_ERROR)
SSL_do_handshake() failed (SSL: error:100000dc:SSL routines:OPENSSL_internal:TOO_MANY_WARNING_ALERTS)
SSL_do_handshake() failed (SSL: error:10000100:SSL routines:OPENSSL_internal:INVALID_COMPRESSION_LIST)
SSL_do_handshake() failed (SSL: error:10000102:SSL routines:OPENSSL_internal:MISSING_KEY_SHARE)
SSL_do_handshake() failed (SSL: error:1000010e:SSL routines:OPENSSL_internal:TOO_MUCH_SKIPPED_EARLY_DATA)
SSL_read() failed (SSL: error:100000b6:SSL routines:OPENSSL_internal:NO_RENEGOTIATION)

Accordingly, the SSL_R_BAD_ALERT, SSL_R_DECODE_ERROR,
SSL_R_TOO_MANY_WARNING_ALERTS, SSL_R_INVALID_COMPRESSION_LIST,
SSL_R_MISSING_KEY_SHARE, SSL_R_TOO_MUCH_SKIPPED_EARLY_DATA,
and SSL_R_NO_RENEGOTIATION errors are now logged at the "info" level.
