This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.
It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).
All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

Otherwise people trying to use this are left wondering "did I not leak, or did
the leak checking code not get called when I exited?".

Replace a kernel header file dependency with files from NetBSD.
They're more complete, and ELF is ELF, whether you're on Linux or a BSD.

Previously, we'd collect every stack frame and then throw some away
when we came to log them. This meant that stack traces were effectively
shorter than the buffers that had been allocated for them. This patch
only stores frames we'll actually output.
Also dynamically call the C++ demangler so we don't have to try to
read mangled names. Because no one knows the mangling of operator new[]
for int arrays off the top of their head.

Include the leaky executable's name in the log output. Fix the "sh" test.
Use uintptr_t instead of intptr_t.
Also fix debug formatting of NULL with %s.

Check that the permissions on the properties file
are exactly as we expect them to be.
Make sure we close the fd if fstat fails.
Refactor the code slightly.

prctl.h uses __BEGIN_DECLS but fails to include sys/cdefs.h
(where it's defined). Code which includes prctl.h without
previously including sys/cdefs.h will fail to compile.
Fixed.

Currently, system properties are passed via the environment
variable ANDROID_PROPERTY_WORKSPACE and a file descriptor passed
from parent to child. This is insecure for setuid executables,
as the environment variable can be changed by the caller.
Modify system property handling so that we get the properties
from a root owned properties file, rather than using an
environment variable. Fall back to the environment variable
if the file doesn't exist.

We don't know that they're not going to be cleaned up by a
C++ global destructor that runs after us. This is the case with
bootanimation, for example.

When each shell leaks ~240 allocations, you can't see the leaks from
the program you ran with "adb shell".

Both libc/include/sys/auxv.h and libc/private/bionic_auxv.h
use _SYS_AUXV_H_ to see if a header file has already been included.
This prevents both of these files from being included at the same
time.
Fix this name conflict.

We had two copies of the backtrace code, and two copies of the
libcorkscrew /proc/pid/maps code. This patch gets us down to one.
We also had hacks so we could log in the malloc debugging code.
This patch pulls the non-allocating "printf" code out of the
dynamic linker so everyone can share.
This patch also makes the leak diagnostics easier to read, and
makes it possible to paste them directly into the 'stack' tool (by
using relative PCs).
This patch also fixes the stdio standard stream leak that was
causing a leak warning every time tf_daemon ran.
