The Hesiod implementation imported into glibc was enhanced to support caller-supplied resolver states. But its only consumer is nss_hesiod, and it supplies the thread-local resolver state. Therefore, this commit changes the Hesiod implementation to use the thread-local resolver state (_res) directly. This fixes bug 19573 because the Hesiod implementation no longer has to initialize and free any resolver state. To avoid any risk of interposition of ABI-incompatible Hesiod function implementations, this commit marks the Hesiod functions as hidden. (They were already hidden using a linker version script.)
