[Bug libc/5737] New: NI_MAXHOST should be available without -D_GNU_SOURCE defined

[ismail at pardus dot org dot tr]

http://sourceware.org/cgi-bin/cvsweb.cgi/libc/resolv/netdb.h.diff?r1=1.47&r2=1.48&cvsroot=glibc&f=h
started to define NI_MAXHOST only if _GNU_SOURCE is defined. 

This is wrong because NI_MAXHOST is also used on BSD systems and this change
breaks lots of applications.

These seem to be defined on at least Tru64 and Solaris, too:

https://www.redhat.com/archives/fedora-devel-list/2008-February/msg01231.html

Perhaps they could just be undefined in strict SUSv3 case, but left defined for
the common case.

This will be a lot of patching if NI_MAXHOST is going to stay _GNU_SOURCE .

Would they work if the guard was changed to __USE_BSD?

I changed the header to define the macro when __USE_MISC is defined.
