thus causing the slow path to be used for those divisors.

Stir directly from the kernel PRNG, without taking less random pid & time
bytes too (when it is possible).
The difference with OpenBSD code is that they have KERN_ARND sysctl for
that task, while we need to read /dev/random
wide string arguments.
Also simplify the code that handles length modifiers and make it
more conservative. For instance, be explicit about the modifiers
allowed for %d, rather than assuming that anything other than L,
q, t, or z implies an int argument.
the first value (environ[0]) to NULL. This is in addition to the
current detection of environ being replaced, which includes being set to
NULL. Without this fix, the environment is not truly wiped, but appears
to be by getenv() until an *env() call is made to alter the enviroment.
This change is necessary to support those applications that use this
method for clearing environ such as Dovecot and Postfix. Applications
such as Sendmail and the base system's env replace environ (already
detected). While neither of these methods are defined by SUSv3, it is
best to support them due to historic reasons and in lieu of a clean,
defined method.
Add extra units tests for clearing environ using four different methods:
1. Set environ to NULL pointer.
2. Set environ[0] to NULL pointer.
3. Set environ to calloc()'d NULL-terminated array.
4. Set environ to static NULL-terminated array.

I guess the original author of the popen() code didn't want to use our
<sys/queue.h> macro's, because the single linked list macro's didn't
offer O(1) deletion. Because I introduced SLIST_REMOVE_NEXT() some time
ago, we can now use the macro's here.
By converting the code to an SLIST, it is more consistent with other
parts of the C library and the operating system.

- Add proper range checking for the 'slen' parameter passed to mkstemps().
- Try all possible permutations of a template if a collision is encountered.
Previously, once a single template character reached 'z', it would not wrap
around to '0' and keep going until it encountered the original starting
letter. In the edge case that the randomly generated starting name used
all 'z' characters, only that single name would be tried before giving up.

This change removes the requirement that an ACL contain no ACL_USER

with a gid the same as those of a file. This requirement is not in the
specification, and not enforced by the kernel's ACL implementation.
