sysctl... This is useful for kern.arandom which (without -B) will
happily return 0 bytes, which isn't too useful or random...
fix spelling (thanks igor!) of settable while I'm here...
Set the value in each test to a different amount to avoid potential
side-effects with other instances of the test (or lingering processes) still
being present on the system
The existing implementation had a broken comparison that could overflow.
Replace this with a check that avoids the overflow before it happens.
Consistently return a maximum value also on the case of negative
arguments since negative is considered an overflow and means
infinity for our current setrlimit().

1. `id -u` -> 0 is now only checked once; the entire test script is now skipped
if this assertion is violated
2. De-dent whitespace, based on 1.
3. Only setup the symlink for $sleep once at the top of the script, and tear it
down once at the bottom of the script
This change by 2-3 times improves performance of misaligned XCOPY and WUT
commands by avoiding unneeded read-modify-write cycles inside ZFS.

code in my last commit. The cc_exec_next is used to track the next
when a direct call is being made from callout. It is *never* used
in the in-direct method. When macro-izing I made it so that it
would separate out direct/vs/non-direct. This is incorrect and can
cause panics as Peter Holm has found for me (Thanks so much Peter for
all your help in this). What this change does is restore that behavior
but also get rid of the cc_next from the array and instead make it
be part of the base callout structure. This way no one else will get
confused since we will never use it for non-direct.

update paths; and include everything in the "base" distribution.
The "games" distribution being optional made sense when there were more
games and we had small disks; but the "games-like" games were moved into
the ports tree a dozen years ago and the remaining "utility-like" games
occupy less than 0.001% of my laptop's small hard drive. Meanwhile every
new user is confronted by the question "do you want games installed" when
they they try to install FreeBSD.
The next steps will be:
2. Removing punch card (bcd, ppt), phase-of-moon (pom), clock (grdc), and
caesar cipher (caesar, rot13) utilities. I intend to keep fortune, factor,
morse, number, primes, and random, since there is evidence that those are
still being used.
3. Merging src/games into src/usr.bin.
This change will not be MFCed.

Some architectures use .rel relocations (for debug data), so they must
be handled.
This was discovered from ctfconvert on ARM object files. The lack of
relocation handling caused all string lookups to return the string at
offset 0 in .debug_str, typically "FreeBSD clang version ..."

order as the .init_array section. Finalisation routines need to be called
in the opposite order as their corresponding initialisation routines but
rtld(1) handles that by calling the function pointers in .fini_array in
reverse order.

When building some of the boot loaders with clang, and DEBUG_FLAGS or
CFLAGS having '-g' in it, clang outputs several assembly directives that
are too new for our version of binutils.
Therefore, assemble the resulting .s files with clang instead. A more
general solution can be implemented when a GNU as-compatible driver for
clang's integrated assembler appears.

from r202992. The refcount on the cache entry is not initialized, so
any attempt to clean the cache will skip over this item since it likely
has a >0 value.
This change is currently a NOP. There is work in progress to support
freeing the cache which requires this change to avoid a memory leak.
