Subject: PAGE_OWNER now depends on STACKTRACE_SUPPORT
One of the enhancements I made to the PAGE_OWNER code was to make
it use the generic stack trace support. However, there are some
architectures that do not support it, like m68k. So, make
PAGE_OWNER also depend on having STACKTRACE_SUPPORT.
This isn't ideal since it restricts the number of places
PAGE_OWNER runs now, but it at least hits all the major
architectures.
