<features.h> is supposed to take user-settable stuff like _GNU_SOURCE
and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in
the C library headers. Instead, bionic used to unconditionally define
_BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header
files (which makes no sense whatsoever).

Fix and use __RENAME (and lose ___RENAME --- two underscores should be
enough for anybody). This was the point of this change, because I want
to use __RENAME to support the two basename variants and the two
strerror_r variants.
Lose a bunch of macros that weren't being used.
Lose three dead files from the DNS code.

1. Add test for __attribute__((constructor/destructor))
and static constructor
2. Compile C++ testlibs with -std=gnu++11

This is an alternate, somewhat simpler, fix that makes it safe to
include both <atomic> and <stdatomic.h> from C++ code in either order.
It means that C code consistently uses one implementation of atomics
and C++ another. We still have to make sure that those two
implementations interoperate correctly at runtime; in particular,
any flavor of atomic object needs to be represented exactly like the
underlying type, with the proper alignment constraint.

Reduce randomization of the test by (1) replacing random() & 255
with hard-coded char and (2) by making State *Iteration function
visit every possible alignment combination instead of 10 random ones.

Glibc calls theirs __ctype_get_mb_cur_max. Make ours match to cut down
on differences between bionic and glibc.

Also scan NDK's unwanted symbols list (to show the things that we're
exporting but the NDK isn't. Symbols hidden in the NDK will be marked
with a *.
Add a -u (--unwanted) flag to disable the first two printed groups
(all symbols in bionic, all symbols in glibc). This is helpful when
wanting to grep in the list of unwanted symbols.
Finally, update the list of known differences between us and glibc.

Do not run symbol lookup on already visited soinfos
Not taking into account already visited libraries
dramatically slows down dlsym in cases when there
are multiple occurrences of a large library in
dependency tree.

Now that -Bsymbolic is fixed, we can hide __libc_malloc_dispatch without
breaking ASAN.

The old definition only worked for functions that didn't use numbered
local labels. Upstream uses '666' not only as some kind of BSD in-joke,
but also because there's little likelihood of any function having
labels that high.
There's a wider question about whether we actually want to go via the
PLT at all in this code, but that's a question for another day.

Add an ordering constraint/fence to __system_property_serial.
This slows down a read on a Nexus 5 from about 50 to about 70 ns,
but avoids the possibility of seeing an inconsistent property value.
Use C11 atomic operations where easy and appropriate.
This code remains not fully C++11 memory model conformant, but
I would now expect the generated code to now be correct with current compilers.

Modify make__NR_name so that only __ARM_NR_ is exempted from the
__NR_ being prepended. This avoids a case where using a name starting
with __ but is not a valid syscall name in SYSCALLS.TXT does not generate
code that will compile but references the function itself and causes
link errors.
Fix all of the directory references from dir_part1 + dir_part2 to
use os.path.join() instead.

Clean up the x86/x86_64 assembler. The motivator (other than reducing
confusion) was that asm.h incorrectly checked PIC rather than __PIC__.
