Also add missing declarations to misc. functions.
Fix clearerr() implementation (previous was broken).
Handle feature test macros like _POSIX_C_SOURCE properly.

With this patch, _and_ an upcoming build/ patch, the destruction
of static C++ objects contained in shared libraries will happen
properly when dlclose() is called.
Note that this change introduces crtbegin_so.S and crtend_so.S which
are currently ignored by the build system.
+ move definition of __dso_handle to the right place
(before that, all shared libraries used the __dso_handle
global variable from the C library).
Note that we keep a 'weak' __dso_handle in aeabi.c to avoid
breaking the build until the next patch to build/core/combo/
appears. We will be able to remove that later.
+ move bionic/aeabi.c to arch-arm/bionic/ (its proper location)

NOTE: The NDK will need to be modified to enable this feature in
the shared libraries that are generated through it.
We simply copy the stuff we need from cutils headers.
A future patch will change cutils to include the private <bionic_atomic_inline.h>

bionic/libc/include/../include/stdlib.h: In function 'int grantpt(int)':
bionic/libc/include/../include/stdlib.h:138:23: warning: parameter '__fd' set but not used [-Wunused-but-set-parameter]
By adding __attribute((unused)) to __fd, the warning is gone, and this
attribute is compatible with gcc-4.4.0, gcc-4.3.1 gcc-4.2.1.
There is no any side effect.

Update ARM atomic ops to use LDREX/STREX. Stripped out #if 0 chunk.
Insert explicit memory barriers in pthread and semaphore code.
For bug 2721865.
Change-Id: I0f153b797753a655702d8be41679273d1d5d6ae7
Added an underscore to _ARM_HAVE_LDREX_STREX to make it match the others.
Added __ARM_HAVE_DMB and __ARM_HAVE_LDREXD when appropriate.
Fixed some typos.

... so that each cloned process at the kernel level can be named
independently. Tools like 'top' can display the CPU/memory statistics
for each process's thread if "Show Threads" mode is on.
With this function in place, we can convert dalvik/Thread.c setThreadName()
function over this function. This feature ought to be provided by the
underlying C library and not coded directly in Dalvik.

GDB looks for specific opcode sequences when trying to recognize a stack
frame as a signal trampoline. The sequences it looks for happen to be those
created when SA_RESTORER is set, since glibc always sets a restorer. This
patch does the same here, so that the trampolines can be correctly identified.

The LD_PRELOAD environment variable allows the user to specify a list of
libraries which should be unconditionally loaded before any others. This
makes possible some useful tricks, such as library interposers.

It's subtle but ix is masked with 0x7f000000 so it can never ever have a value
greater than 0x80000000. So I switched to using the unmasked hx and added a
cast as a reward to the compiler for being right.
I checked the original routines that e_j0f.c was ported from (in e_j0.c) and
the double's don't use 0x80000000 so this issue didn't exist there.
Let that be a warning to those that just slap on casts to shut up the compiler,
sometimes it's sniffed out a bug for you. :-)
Similar fixes in the other functions.

I'm not sure if this is a correct fix or not.
Also need to find out why 1.6 does not have this issue.
