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 (It's since been replaced
by gdtoa, and we'll have to follow at some point, but for now this doesn't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.

0133944b09 Clean up our OpenBSD usage.
Also undo some of the mess where we have OpenBSD <stdio.h> but a mix of
different BSD's implementations.

In this first pass, I've only moved easy OpenBSD stuff.

652289942d bionic: call stdio cleanup on exit
As of 61e699a133, stdio clean up
functions are no longer registered in atexit and must be called
manually via __cleanup.

The issue this fixes is some static binaries linked against bionic
cannot output properly when piped or redirected because the buffer
is not flushed before closing.

This is done by pulling in exit.c (and other dependencies) from
netbsd.

eb847bc866 Fix x86_64 build, clean up intermediate libraries.
The x86_64 build was failing because clone.S had a call to __thread_entry which
was being added to a different intermediate .a on the way to making libc.so,
and the linker couldn't guarantee statically that such a relocation would be
possible.

  ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC

This patch addresses that by ensuring that the caller and callee end up in the
same intermediate .a. While I'm here, I've tried to clean up some of the mess
that led to this situation too. In particular, this removes libc/private/ from
the default include path (except for the DNS code), and splits out the DNS
code into its own library (since it's a weird special case of upstream NetBSD
code that's diverged so heavily it's unlikely ever to get back in sync).

There's more cleanup of the DNS situation possible, but this is definitely a
step in the right direction, and it's more than enough to get x86_64 building
cleanly.

61e699a133 Clean up abort.
* 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.

42b2c6a5ee Clean up the argc/argv/envp/auxv handling.
There's now only one place where we deal with this stuff, it only needs to
be parsed once by the dynamic linker (rather than by each recipient), and it's
now easier for us to get hold of auxv data early on.

f3cfcd869d ARM: make CRT_LEGACY_WORKAROUND work as intended
To properly support legacy ARM shared libraries, libc.so needs
to export the symbols __dso_handle and atexit, even though
these are now supplied by the crt startup code.

This patch reshuffles the existing CRT_LEGACY_WORKAROUND
conditionally compiled code slightly so it works as the
original author likely intended.

In particular this affects assert(3) and __cxa_pure_virtual, both of
which have managed to confuse people this week by apparently aborting
without reason. (Because stderr goes nowhere, normally.)

3964084282 Enable functional DSO object destruction
Unfortunately, legacy .so files for ARM don't have a correct crtbegin file.
Consequently, we have to grandfather the old __dso_handle behaviour.
Add some ifdefs for ARM to allow it to use the old code until we can work
out a transition.

8132626b71 Fix strtod security bug.
To avoid introducing NULL checks everytime a Bigint computation
is performed, introduce a special value (BIGINT_INVALID) and only
check for it when absolutely needed (which means when the code
needs to access the Bigint's internal structure fields).
