9a1d3976f1 Reimplement our no-op utmp.h functions more simply.
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!

1cc755c8cf Fully disable clang format where needed.
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.

fdaf82f96b Link .clang-format file to system/core one.
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.

fbac97a54c Move NetBSD string routines to OpenBSD.
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...

468efc80da Reimplement popen(3)/pclose(3).
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.

9b1ca569db libc: Add support to allow library calls to find appropriate shell executable for a process
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.

b6b5cb5389 Ignore all __weak_alias in OpenBSD libC.
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.

b902641d73 Implement twalk(3), add unit tests.
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.

Stupidly I found this bug by accident when writing the existing

out that libcore always uses an INET6_ADDRSTRLEN-sized buffer
even when working with AF_INET addresses.

205c7887ad Clean up reentrancy cruft.
The DNS copy of reentrant.h was unused, so remove it.

The strtod implementation can use the upstream-netbsd reentrant.h and
get a little closer to what was then upstream. (It's since been replaced
by gdtoa, and we'll have to follow at some point, but for now this doesn't
make anything any worse.)

ANDROID_CHANGES is (now) only used in the DNS code, so push the -D
down.

The <locale.h> change prevents an LP32 hack from leaking into LP64.
