Detect and select i586/i686 implementation at run-time

We detect i586 and i686 features at run-time by checking CX8 and CMOV
CPUID features bits. We can use these information to select the best
implementation in ix86 multiarch. HAS_I586/HAS_I686 is true if i586/i686
instructions are available on the processor.

Due to the reordering and the other nifty extensions in i686, it is not
really good to use heavily i586 optimized code on an i686. It's better
to use i486 code if it isn't an i586. USE_I586/USE_I686 is true if
i586/i686 implementation should be used for the processor. USE_I586
is true only if i686 instructions aren't available. If i686 instructions
are available, we always choose i686 or i486 implementation, in that order,
and we never choose i586 implementation for i686-class processors.

Don't fall back to mmap if the original arena is not corrupt

The new logic to find an uncontended non-corrupt arena misses a case
where the current arena is contended, but is not corrupt. In the
degenerate case, this is the only arena. In both cases, the logic
falls back to using mmap despite there being an available arena.

Attached patch by Josef Bacik makes sure that all arenas are indeed
corrupt before falling back to malloc. Verified on x86_64 that the
testsuite does not regress.

 * malloc/arena.c (reused_arena): return NULL only if all
 arenas are corrupt.

Remove incorrect register mov in floorf/nearbyint on x86_64

The change in 0b5395f052ee09cd7e3d219af4e805c38058afb5 replaced calls
to __get_cpu_features@plt followed by a mov from rax to rdx, with a
single macro LOAD_RTLD_GLOBAL_RO_RDX. It is pretty clear that there
was a typo in s_floorf and __nearbyint due to which the (now incorrect)
mov was not removed. This patch removes that mov.

sparc: fix sigaction for 32bit builds [BZ #18694]

Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction
struct to pass conform tests, but it ended up also changing the ABI for
32 bit builds. For 64 bit builds, changing the long to two ints works,
but for 32 bit builds, it inserts 4 extra bytes. This leads to many
packages randomly failing like bash that spews things like:
 configure: line 471: wait_for: No record of process 0

Bracket the new member by a wordsize check to fix the ABI for 32bit.

    Don't generate PLT relocations for now binding

    There is no need for PLT relocations with -z now. We can use GOT

Since ld.so is built with -z now, there are no PLT relocations and this
calloc won't be used:

Assuming we do want to keep PLT relocations in ld.so so that malloc
functions in ld.so can be overridden, ld.so should be built with -z now.
There is no reason to build ld.so with -z now since ld.so is the one
doing BIND_NOW. The only thing we get with -z now on ld.so is DT tag:

 0x0000000000000018 (BIND_NOW)
 0x000000006ffffffb (FLAGS_1) Flags: NOW

Fix stack overflow due to large AF_INET6 requests

Resolves #16072 (CVE-2013-4458).

This patch fixes another stack overflow in getaddrinfo when it is
called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914,
but the AF_INET6 case went undetected back then.

Restore _res correctly

getaddrinfo works around the resolver functionality to avoid automatic

Fix fstat() not trying to call fxstat64() on sparc64

sparc64 fxstat implementation should follow the same code path as on
i386, first trying fxstat64() and falling back to fxstat() only when
it is not available. Otherwise, nanosecond times resolution will not
be available.

sparc64 is unlike other 64-bit architectures in that fxstat64() has
not been historically always available in the kernel.
