* A dlmalloc usage error shouldn't call abort(3) because we want to
cause a SIGSEGV by writing the address dlmalloc didn't like to an
address the kernel won't like, so that debuggerd will dump the
memory around the address that upset dlmalloc.
* Switch to the simpler FreeBSD/NetBSD style of registering stdio
cleanup. Hopefully this will let us simplify more of the stdio
implementation.
* Clear the stdio cleanup handler before we abort because of a dlmalloc
corruption error. This fixes the reported bug, where we'd hang inside
dlmalloc because the stdio cleanup reentered dlmalloc.

- eventfd.cpp and eventfd.s will output to the same file when building libc.a
out/target/product/*/obj/STATIC_LIBRARIES/libc_intermediates/WHOLE/libc_common_objs/eventfd.o
- And then `eventfd` will undefined when statically linked to libc.
Also add a unit test.

For some reason, socketcalls.c was only being compiled for ARM, where
it makes no sense. For x86 we generate stubs for the socket functions
that use __NR_socketcall directly.

We only need one logging API, and I prefer the one that does no
allocation and is thus safe to use in any context.
Also use O_CLOEXEC when opening the /dev/log files.
Move everything logging-related into one header file.

The defines HAVE_32_BYTE_CACHE_LINES and ARCH_ARM_USE_NON_NEON_MEMCPY
are not used by any code. The previous memcpy code that used these
has been split into different architecture versions to avoid the need
for them.

Move arch specific code for arm, mips, x86 into separate
makefiles.
In addition, add different arm cpu versions of memcpy/memset.

This gets us back to using vfork now our ARM vfork assembler stub is
fixed, and adds the missing thread safety for the 'pidlist'.

This is actually a slightly newer upstream version than the one I
originally pulled. Hopefully now it's in upstream-freebsd it will
be easier to track upstream, though I still need to sit down and
write the necessary scripts at some point.

The old scandir implementation didn't take into account the varying
size of directory entries, and didn't correctly clean up on its
error exits.

imgtec pointed out that pthread_kill(3) was broken, but most of the
other functions that ought to return ESRCH for invalid/exited threads
were equally broken.

* commit '0a2cb815974ea96af664fa966079966a08916722':
Simplify __stack_chk_fail, and fix it so we get debuggerd stack traces.
libc_bionic.a is already compiled -Werror, but this one file gets
compiled into its own library because it needs to be compiled with
-fno-stack-protector.
