hesiod: Always use thread-local resolver state [BZ #19573]
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.)
