After bug report 262 (from 2010)
https://austingroupbugs.net/view.php?id=252
the Austin Group decided to require processing of "--" by the "."
and "exec" commands to solve a problem where some shells did
option processing for those commands (permitted) and others did
not (also permitted) which left no safe way to process a file
with a name beginning with "-".

This has finally made its way into what will be the next version of
the POSIX standard.

Since this shell did no option processing at all for those commands,
we need to update.  This is that update.

The sole effect is that a "--" 'option' (to "." or "exec") is ignored.
This means that if you want to use "--" as the arg to one of those
commands, it needs to be given twice ". -- --".  Apart from that there
should be no difference at all (though the "--" can now be used in other
situations, where we did not require it before, and still do not).

Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).

Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
  but each port uses different PAGE_SIZE value (4096 or 8192)
  due to historical reasons.
- Currently module(7) binaries are built per each port so
  all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
  PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
  are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
  src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
  for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
  among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
  support m68k ports where PAGE_SIZE==8192.
  (though this would affect only if static binaries built on
  4k page hosts are executed on 8k page hosts)

To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.

(That said, it's not clear the mutex_enter/exit is needed unless
refcnt > 0 already, in which case maybe it would be a win to switch
from the membar implied by mutex_enter to the membar implied by
atomic_store_release -- which I would generally expect to be much
cheaper.  And a little clearer without a long comment.)

  => This is used only in fd_close and fd_abort, where it holds.
- Move bounds check assertion in fd_putfile to where it matters.
- Store fd_dt with atomic_store_release.
- Move load of fd_dt under lock in knote_fdclose.
- Omit membar_consumer in fdesc_readdir.
  => atomic_load_consume serves the same purpose now.
  => Was needed only on alpha anyway.
