#12602: Tor fails to build on SSL with no compression.

Parent ID:          |         Points:
--------------------+----------------------------------
 OpenBSD removed compression from LibreSSL, so tor no longer compiles due
 to comp_methods missing.

 This patch allows it to compile once again... but not sure if this is the
 best way.

    /* Don't actually allow compression; it uses ram and time, but the data
     * we transmit is all encrypted anyway. */
 -  if (result->ctx->comp_methods)
 -    result->ctx->comp_methods = NULL;
 +  SSL_CTX_set_options(result->ctx, SSL_OP_NO_COMPRESSION);
