PAGE_(SIZE|SHIFT|MASK) defines that evaluate to variables on the
sparc architecture;
ok otto@ tested on my reanimated ss20

on sparc, it expands to something that just plain does not work,
because the page size can be variable.  Sorry we didn't spot this
before.  Backing it all out to allow sparc to build; please find a
different way to fix it.

(MALLOC_OPTIONS=L). It was too slow to turn on by default, and we
don't do optional security.
requested by deraadt@ grumbling ok otto@

Move all runtime options into a structure that is made read-only
(via mprotect) after initialisation to protect against attacks that
overwrite options to turn off malloc protections (e.g. use-after-free)
Allocate the main bookkeeping data (struct dir_info) using mmap(),
thereby giving it an unpredictable address. Place a PROT_NONE guard
page on either side to further frustrate attacks on it.
Add a new 'L' option that maps struct dir_info PROT_NONE except when
in the allocator code itself. Makes attacks on it basically impossible.

a page to 0. P default will be changed in a separate commit.

a separate symbolic constant for the leeway we allow when moving
allocations towards the end of a page. No functional change.

(might catch errors closer to the trouble spot) and junk fill pages just
before reuse instead of immediate (we can't access the page anyway)
since we set PROT_NONE in the F case. ok djm@
