eec560a7c3 Correctly read symlinks from cpio files.
While I'm here, fix a bug in reading filenames from
cpio files.  (Copy should count the length of the name,
not the number of bytes available for input.)

0b0ae8e16e Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

Tested on: i386 sparc64

48517ca7da Back out the "clean_environment()" function from libutil.
Further contemplation has convinced me that this was
not going to really solve the problem of environment-poisoning
without raising serious administrative headaches.  There
must be a better way...

8b8fb9aae5 Add a clean_environment call to libutil.
This function removes all environment variables except
the ones listed on a "whitelist."

The function accepts two whitelist arguments.
If the first is NULL, a built-in default list will be
used.  This allows callers to get a variety of behaviors:
  * Default screening: provide NULL for both lists
  * Custom screening: provide a custom list for the first argument
  * Modified default screening: provide NULL for first arg,
     list of additional variables to preserve in the second arg

fd2c94bc06 Backed out rev.1.6 and subsequent copying of it (bogus addition of
-static to CFLAGS).  It just turned rev.1.5 into an obfuscated no-op.
As explained in the log for rev.1.5, testing should be done in the
host environment but there is a problem in cross-compilation environments.
As not explained in the log for rev.1.6, there was apparently a practical
problem with cross-compiling (makeworld should have set -static in
LDFLAGS but apparently didn't).  Cross-compilation was especially
complicated because the relevant programs are test programs that were
run at beforeinstall time -- dynamic libraries might or might not exist
depending on the build options.  The complications became moot in
rev.1.8 when beforeinstall was renamed "test".

40452493ee Make the resolver(3) and many associated interfaces much more reentrant.
The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now
with what should be totally reentrant, and h_errno values will now
be preserved correctly, but this does not affect interfaces such as
gethostbyname(3) which are still mostly non-reentrant.

In all of these relevant functions, the thread-safety has been pushed
down as far as it seems possible right now.  This means that operations
that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected
still under global locks that getaddrinfo(3) defines, but where possible
the locking is greatly reduced.  The most noticeable improvement is
that multiple DNS lookups can now be run at the same time, and this
shows major improvement in performance of DNS-lookup threaded programs,
and solves the "Mozilla tab serialization" problem.

No single-threaded applications need to be recompiled.  Multi-threaded
applications that reference "_res" to change resolver(3) options will
need to be recompiled, and ones which reference "h_errno" will also
if they desire the correct h_errno values.  If the applications already
understood that _res and h_errno were not thread-safe and had their own
locking, they will see no performance improvement but will not
actually break in any way.

Please note that when NSS modules are used, or when nsdispatch(3)
defaults to adding any lookups of its own to the individual libc
_nsdispatch() calls, those MUST be reentrant as well.

09eb839cca Add bsde_add_rule(), which is similar to bsde_set_rule() except that
the caller does not specify the rule number -- instead, the kernel
module is probed for the next available rule, which is then used.

7e0166bc79 There are consumers of rwlocks, inluding our own libc, that depend on

a similarly named symbol does for statically initialized mutexes.
