Images in the shared cache have their segments mapped non-contiguously.  We
don't know how to find where the non-__TEXT segments actually are.  Also, the
code assumes that the image is mapped contiguously in various places.  So, we
just ignore those segments.

Treating the non-contiguous segments as though they were contiguous caused
their apparent memory ranges to overlap, leading to addresses being attributed
to the wrong module, let alone symbol.

The timezone information for Morocco was updated recently.

When there are no further time changes, the function find_dst_change() will
return (year_end + 1). This patch ensures that we don't lookup the wrong
DynamicDST entry in such a case.
