Add ares helpers into sssd

This patch adds ares parsing functions that are not yet upstreamed
together with a private ares header file (ares_dns.h) that contains
some necessary macros for parsing common structures in the replies.

Users of these two parsing functions must also include the header files
ares_parse_{srv,txt}_reply.h that contain the function and structures
declarations that should eventually end up in upstream ares.h
