Core: connect() error log message made more verbose
There was a major problem in logs: we could not identify to which servers
connect() has failed. Previously log produced:
ngx_log_error(NGX_LOG_ALERT, ngx_cycle->log, ngx_socket_errno,
"connect() failed");
And now we'll have an address or unix socket in log:
ngx_log_error(NGX_LOG_ALERT, ngx_cycle->log, ngx_socket_errno,
"connect() to %V failed", &peer->server.name);
Message format has chosen to be exact as it is used in ngx_event_connect.c:242
with similar error logging:
ngx_log_error(level, c->log, err, "connect() to %V failed",
pc->name);
So everywhere connect() could fail we'd get a uniform and verbose error message
in log.
