Revision 1502305

Use svn_pool_create() instead of apr_pool_create().

Presently, this means that if an apr_pool_create() fails, abort_fn() will be
called.  None of those plafces check for NULL results from the allocator,
so the net effect is changing a NULL dereference to calling our pool.c
function abort_on_pool_failure() (which is marginally better).
