PATCH: revert RUN_HOOK changes for BPs

[Greg McGary]

These changes didn't do what I wanted, so I took them out and
instead added an __unbounded qualifier.

No build regressions.  No non-BP binary changes.

OK?

	* include/libc-symbols.h (symbol_set_declare): Revert 2000-06-26 mods.
	* include/set-hooks.h (RUN_HOOK): Revert 2000-06-26 mods.  Qualify
	ptr as __unbouned.
