(This is part of a larger changeset which is intended to reduce diff only,
thus some prototypes were left intact since they will be changed in the
future).
Verified with: md5(1)
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.
mpool_open(3) - it is *not* really used for synchronization; in fact,
it is not used at all.

MFC after: 3 days
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.

Only warnings that could be fixed without changing the generated object

Some review from -hackers (some time ago), and I think the best way to
get this improved (if it needs improving) or updating, is to bring it in.

adding (weak definitions to) stubs for some of the pthread
functions. If the threads library is linked in, the real
pthread functions will pulled in.
Use the following convention for system calls wrapped by the
threads library:
__sys_foo - actual system call
_foo - weak definition to __sys_foo
foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads
library from foo to _foo. In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde). All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes. <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE. We have recursive mutexes, but would like to avoid
using them if possible.
Remove uneeded includes of <errno.h> from a few files.
Add $FreeBSD$ to a few files in order to pass commitprep.

quitting every time. The way to free a CIRCLEQ was to loop until
the current == current->head, but the way to free a TAILQ is to loop
until current->head == NULL.
In any case, the CORRECT way to do it is a loop of TAILQ_EMPTY() checks
and TAILQ_REMOVE()al of TAILQ_FIRST(). This bug wouldn't have happened
if the loop wasn't hard-coded...
There may be more bugs of this type from the conversion.
