resolv: Remove internal and unused definitions from <resolv.h>

Browse Source 
The RES_F_* constants are only used with the private _res._flags
member.  RES_EXHAUSTIVE is unused.  The removed function
declarations refer to functions not actually exported by glibc,
so they are unusable by applications.
