{get,set}domainname aren't in POSIX but are widely-implemented
extensions.
The Linux kernel provides a setdomainname syscall but not a symmetric
getdomainname syscall, since it expects userspace to get the domain name
from uname(2).

This patch uses __kernel_vsyscall instead of "int 0x80"
as the syscall entry point. AT_SYSINFO points to
an adapter to mask the arch specific difference and gives a
performance boost on i386 architecture.

"I have none of these capabilities" is a legitimate response, and
distinct from "I don't know what my capabilities are". It's the latter
I meant to test for.

The stack offsets assumed we'd pushed %ebx. Unlike x86-64 we can't fall
through, but we can avoid repeating work we've already done.

Even though the size parameter to epoll_create(2) is (otherwise) unused,
passing in size <= 0 is explicitly documented as an error.
This change fixes the LTP epoll01 testcase.

The clone syscall accepts NULL child stacks, interpreting this to mean
the child gets a copy of the parent's stack with copy-on-write
semantics. However clone(2) is explicitly documented to treat this an
an error.
"Fortunately" every architecture's __bionic_clone implementation pushes
something onto the child stack before making the clone syscall. So we
know fixing this won't break legacy apps, because any app that tried
using a NULL child stack would have died with SIGSEGV.
This change fixes the LTP clone04 testcase.

Also guard both these GNU extensions with _GNU_SOURCE.
Also improve the tests to test each case on both the current thread and
another thread, since the code paths are totally different.

pthread_barrier_smoke test uses WaitUntilThreadSleep() to wait until
BarrierTestHelper threads sleep in pthread_barrier_wait(). But this
is flaky as there a two futex_wait places in pthread_barrier_wait.
This patch modifies this test to avoid using WaitUntilThreadSleep().

The free track mechanism could fail if, at the same time a free occurs,
another thread is trying to free and verify the same allocation. This
doesn't work if the freed allocation is added to the list and we still
do work on it. The fix is to only add to the free list when we are done
with the allocation.
Also fix a problem where the usable size is computed incorrectly because
two of the arguments where reversed.
In addition, add a check that the allocation being verified has the correct
tag before trying to check the body of the allocation.
Add a test to catch the original failure.
Add a test for the tag being different.

ignored, but do not produce an error. Fixed this so that each

FreeBSD doesn't seem interested in having low-quality implementations of
these functions:
cacoshl, cacosl, casinhl, casinl, catanhl, catanl, ccoshl, ccosl, cexpl,
clog, clogf, clogl, cpow, cpowf, cpowl, csinhl, csinl, ctanhl, ctanl.
And they still haven't got round to writing good implementations, so for
now let's just take the NetBSD ones so we have the full set.

0 byte allocations can cause problems if they are immediately followed
by another allocation with no header, as both allocations will have the
same address. Treat 0 byte allocations as 1 byte allocations so that
debug_iterate will return separate addresses for them.
