Remove excess declarations from unistd.h for XPG3/XPG4 (bug 17665).
For XPG3/XPG4 (defined __USE_XOPEN && !defined __USE_UNIX98), unistd.h declares many functions that should only be declared for __USE_MISC (none of them are in XPG3/XPG4): sethostname sethostid getdomainname setdomainname vhangup revoke profil acct getusershell endusershell setusershell daemon. The whole block with the [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)] conditional contains only functions that are not in XPG3/XPG4, so this patch simply changes the conditional. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). [BZ #17665] * posix/unistd.h [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)]: Change conditional to [__USE_MISC].
