c9f30aaaf7 When allocating memory, zero out them if we don't intend to overwrite them 
all; before freeing memory, zero out them before we release it as free
heap.  This will eliminate some potential information leak issue.

While there, remove the PURIFY option.  There is a slight difference between
the new behavior and the old -DPURIFY behavior, with the latter initializes
memory with 0xff's.  The difference between old and new approach does not
generate observable difference.

Obtained from:	OpenBSD (partly).

(This is part of a larger changeset which is intended to reduce diff only,

a5906b6cd2 I found "portsdb -u" dumps core with recent INDEX file, and this is 
caused by refering broken (uninitialized?) pointer which is retrieved
from __bt_new() (and from mpool_new()).

I don't know why this linp[0] is read before stored because this
should be controlled by .lower and .upper member of PAGE structure
which are correctly initialized.

But this workaround fixes the problem on my environment and this
module has #ifdef PURIFY option which initializes new and reused
memory from mpool by memset(p, 0xff, size) like as I did.

Please feel free to fix the real bug instead of my workaround.

it is not used at all.

6bc615b0a1 Fix a sizeof error in __bt_put: when writing they key and data sizes 
to a buffer in the big key/data case, memmove() was used on pointers
to size_ts, but only sizeof(u_int32_t) bytes where copied. This broke
on big_endian architectures where sizeof(size_t) > sizeof(u_int32_t).

This bug broke portupgrade (by way of ruby_bdb1) on sparc64.
