find bug in dns resovle

[nginx at aqcx.com]

Igor Sysoev,！

	my name is zyb,come from china.

	and i wanna to modify ngx_resolve.c to add function to support mx resolve,if i modify ,i can present it just here?

	i have one suggesiton:
		i wish nginx's common moudle  can be orgnized as lib ,such as event module,string ,log and memory managmeng module and so on. if so ,it will do favor  nginx to be used by more developer in diffirent application.

	thanks
