apr_XXX_set_inherit() brokenness
two problems, I think:
1) The special cleanup needs to be removed if the apr_foo is closed
before the pool goes away.
Example:
mod_file_cache/mmap-ed file
open file
create mmap
close file
The inherit cleanup is still in place at this point.
2) Either there should be a no-op plain cleanup or the close-pool code
should not call plain_cleanup if that ptr is NULL.
run_cleanups() unconditionally calls cleanup->plain_cleanup(), so
this tries to branch to zero if this is the inherit cleanup.

The Crux of the problem is in the disconnected way the entire cleanup API
is working.
apr_pool_child_cleanup_kill() is pure BS, since it also kills the plain cleanup.
Nobody uses it, so I'm killing the function.
I'll replace it with a apr_pool_child_cleanup_set() that allows you to replace
the original child cleanup with a new cleanup, given the void* and plain cleanup.
