SSL may be activated implicitely if a server relies on SSL, even without check-ssl keyword. This is performed by init_srv_check() function. The main operation is to change xprt layer for check to SSL. Prior to this patch, <use_ssl> check member was also set, despite not strictly necessary. This has a negative side-effect of rendering check-reuse-pool ineffective. Indeed, reuse on check is only performed if no specific check configuration has been specified (see tcpcheck_use_nondefault_connect()). This patch fixes check reuse with SSL : <use_ssl> is not set in case SSL is inherited implicitely from server configuration. Thus, <use_ssl> is now only set if an explicit check-ssl keyword is set, which disables connection reuse for check. This must be backported up to 3.2.
