Improve <sys/cdefs.h>.
Fix and use __RENAME (and lose ___RENAME --- two underscores should be
enough for anybody). This was the point of this change, because I want
to use __RENAME to support the two basename variants and the two
strerror_r variants.
Lose a bunch of macros that weren't being used.
Lose three dead files from the DNS code.
