1698	A minor optimization for ngx_log_debug	chronolaw@…		"In ngx_log_debug, it will compare log_level and level use '&'，but if we compose multi levels it will case a compiler error (suggest parentheses around arithmetic in operand of ‘|’).

For example :
ngx_log_debug2(
    NGX_LOG_DEBUG_HTTP|NGX_LOG_DEBUG_CONNECTION,...)

this code will be:

log->log_level & NGX_LOG_DEBUG_HTTP|NGX_LOG_DEBUG_CONNECTION

So I think we should add parentheses around 'level' in macro.
Please check the patch,Thanks all of you, nginx team.

(by the way, I can not config hg's emailbomb, please forgive my behavior)
