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.

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.

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

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.
