b4637f4f1f Atomic/SMP update. [manual merge to dalvik-dev]
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.

78c1c04ced pthread: introduce pthread_setname_np() as a mean to give names to threads
... 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.

e4fa46e75c Set SA_RESTORER in sigaction()
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.

4fd42c1dc0 Added support for LD_PRELOAD
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.

c1f8dd9f0b Sometimes the compiler is very right! Found bug in bessel routines for float.
Original compiler error:

target arm C: libm <= bionic/libm/src/e_j0f.c
bionic/libm/src/e_j0f.c: In function 'j0f':
bionic/libm/src/e_j0f.c:66: warning: comparison between signed and unsigned integer expressions
bionic/libm/src/e_j0f.c: In function 'y0f':
bionic/libm/src/e_j0f.c:140: warning: comparison between signed and unsigned integer expressions
target arm C: libm <= bionic/libm/src/e_j1.c

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.

1698d9ebfc Fixed support for RTLD_NEXT in dlsym()
The previous implementation of this flag was broken--it behaved identically
to RTLD_DEFAULT.  This adds a proper implementation, which examines the address
of the calling function, and uses it to determine which library to use to begin
the symbol search process.
