sh: rework memory limits to work with LMB.
This reworks the memory limit handling to tie in through the available LMB infrastructure. This requires a bit of reordering as we need to have all of the LMB reservations taken care of prior to establishing the limits. While we're at it, the crash kernel reservation semantics are reworked so that we allocate from the bottom up and reduce the risk of having to disable the memory limit due to a clash with the crash kernel reservation.
