* include/shlib-compat.h (SHLIB_COMPAT): Take a third argument,
indicating the first version set to obsolete the conditionalized code.
(compat_symbol): New macro.
* scripts/abi-versions.awk: For subsumed versions, make ABI_* defn's
rhs be the ABI_* macro for the subsuming version. Assign increasing
integer values to the ABI_* macros for supported versions.
* sysdeps/gnu/siglist.c: Use new SHLIB_COMPAT convention, and use
compat_symbol macro.
