Symbol __rand48_seed, __rand48_mult and __rand48_add are duplicate when switch -fcommon to -fno-common, but this was already fixed upstream, so sync with upstream's version.

Change 75830fb836 to fix _nres
initialization to be thread safe accidentally introduced a behavior
change whereby res_init() became a no-op. It also failed to remove all
direct accesses to _nres.
Move the file over to C++ so we can let RAII ensure we're always holding
a lock while using the global state, make all callers access the global
state via this class, and restore the previous behavior of res_init().

Now we're being marked down for our poor coverage, we may as well remove
more broken cruft. Despite the amount of effort that seems to have gone
into pututline(), it wasn't working with the other utmp.h functions (in
particular, utmpname()), and wasn't declared in the header file!

Even with formatting off, clang still tries to rearrange the include
files or the using statements, so disable that too.
Test: Verified that the include directories are not rearranged.

Use the .clang-format-2 found in system/core instead of this which is
not actually being used.
Also, enable clang-format running by default.
All upstream directories are marked as ignoring formatting so that
their source files are not modified.

NetBSD seems to be the least well maintained of our three BSD upstreams,
and it's already the one we use the least. Let's push a little further
in that direction...

pclose(3) is now an alias for fclose(3). We could add a FORTIFY check
that you use pclose(3) if and only if you used popen(3), but there seems
little value to that when we can just do the right thing.
This patch also adds the missing locking to _fwalk --- we need to lock
both the global list of FILE*s and also each FILE* we touch. POSIX says
that "The popen() function shall ensure that any streams from previous
popen() calls that remain open in the parent process are closed in the
new child process", which we implement via _fwalk(fclose) in the child,
but we might want to just make *all* popen(3) file descriptors O_CLOEXEC
in all cases.
Ignore fewer errors in popen(3) failure cases.
Improve popen(3) test coverage.

Library calls like system() and popen() invoke the shell executable
pointed to by '_PATH_BSHELL' in order to run the command passed into the
function. The _PATH_BSHELL points to /system/bin/sh by default and thus
breaks any vendor process trying to use system() / popen(), as they are
denied access to system shell by selinux.
This CL make necessary changes, so the implmentations of system() and popen()
can use the appropriate shell (e.g. /vendor/bin/sh for processes running
out of /vendor partition). Also, changes the implementation of system()
and popen().
Bug: 64832610
Test: Manual, Using a test program running from /system/bin and
/vendor/bin to ensure correct shell is being used.

Various things:
* work around -Wnullability-completeness.
* use C++ casts in C++ and C casts in C.
* stop using attributes clang doesn't support (such as `warning`).
* remove duplicate definitions of XATTR_CREATE and XATTR_REPLACE.

GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

I've also added insque(3) and remque(3) (from NetBSD because the OpenBSD
ones are currently broken for non-circular lists).
I've not added the three hash table functions that should be in this header
because they operate on a single global hash table and thus aren't likely
to be useful.

This shouldn't be public API, isn't supported on x86/x86_64, and it's
unlikely anyone would have actually seen the message before anyway.
Using __libc_fatal makes it much more likely to be seen.

* Register cleanup function with atexit
instead of calling it explicitly on
exit()
* abort() no longer calls _cleanup:
Flushing stdio buffers on abort is no
longer required by POSIX.
* dlmalloc no longer need to reset cleanup
(see above)
* Upstream findfp.c makebuf.c setvbuf.cexit.c

Stupidly I found this bug by accident when writing the existing
tests, but I didn't think any real code would hit it. It turns
out that libcore always uses an INET6_ADDRSTRLEN-sized buffer
even when working with AF_INET addresses.

Also ensure we have symbols for htonl, htons, ntohl, and ntohs.
gtest doesn't like us using the macro versions in ASSERT_EQ.
