Update the resolver in libc to BIND9's one.

2006-03-21T16:11:11Z

Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc. Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them). Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe. Reviewed by: arch@ (no objection)

Correct a comment.

Staticize two tables thare are not visible in and which are also local in Solaris' libresolv. Remove two functions that are not referenced in libc nor anywhere else I can find, not visible in and which are also local in Solaris libresolv.

Implement the weak aliases for private entry points in the inet_*

and res_* modules in a way that works for ELF. I moved the aliases out of res_stubs.c and into the individual modules where the entry points are defined. Weak aliases don't work in ELF unless that is the case. (Actually, I'm surprised it worked for a.out.) This should fix the undefined "inet_addr" and related symbols in various applications that fail to include or as they are supposed to do.
