This patch fixes the vDSO symbol used directed in IFUNC resolver where
they do not have an associated ODP entry leading to undefined behavior
in some cases. It adds an artificial OPD static entry to such cases
and set its TOC to non 0 to avoid triggering lazy resolutions.

The RFC 6335 allows services that start with digit (like 3com-tsmux).
These were parsed as port number which this patch fixes.

We cannot use fnegd in this code, as fnegd was added in v9.
Only fnegs exists in v8 and earlier.
[BZ #15985]
* sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd
on pre-v9 cpus, use a fnegs+fmovs sequence instead.

The register keyword doesn't add any information to the examples
and is not useful for modern compilers.
ChangeLog:
2013-11-06 Will Newton <will.newton@linaro.org>
* manual/memory.texi (Malloc Examples): Remove register
keyword from examples.

A very large alignment argument passed to mealign/posix_memalign
causes _int_memalign to enter an infinite loop. Limit the maximum
alignment value to the maximum representable power of two to
prevent this from happening.

[BZ #16038]
* malloc/hooks.c (memalign_check): Limit alignment to the
maximum representable power of two.
* malloc/malloc.c (__libc_memalign): Likewise.
* malloc/tst-memalign.c (do_test): Add test for very
large alignment values.
* malloc/tst-posix_memalign.c (do_test): Likewise.

Currently for AF_INET lookups from the hosts file, buffer sizes larger
than INT_MAX silently overflow and may result in access beyond bounds
of a buffer. This happens when the number of results in an AF_INET
lookup in /etc/hosts are very large.
There are two aspects to the problem. One problem is that the size
computed from the buffer size is stored into an int, which results in
overflow for large sizes. Additionally, even if this size was
expanded, the function used to read content into the buffer (fgets)
accepts only int sizes. As a result, the fix is to have a function
wrap around fgets that calls it multiple times with int sizes if
necessary.

Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.

These inputs cover all normal processing paths for pow including all
its slow paths.

A more comprehensive set of inputs for exp, including all slow paths.
The inputs have been shuffled so that they don't give a false-positive
due to a hot cache.

This patch intends to unify both strcpy and stpcpy implementationsi
for PPC64 and PPC64/POWER7. The idead default powerpc64 implementation
is to provide both doubleword and word aligned memory access.
For PPC64/POWER7 is also provide doubleword and word memory access,
remove the branch hints, use the cmpb instruction for compare
doubleword/words, and add an optimization for inputs of same alignment.

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.

[BZ #9954]
With the following /etc/hosts:
127.0.0.1 www.my-domain.es
127.0.1.1 www.my-domain.es
192.168.0.1 www.my-domain.es
Using getaddrinfo() on www.my-domain.es, trigger the following assertion:
../sysdeps/posix/getaddrinfo.c:1473: rfc3484_sort: Assertion
`src->results[i].native == -1 || src->results[i].native == a1_native' failed.
This is due to two different bugs:
- In rfc3484_sort() rule 7, src->results[i].native is assigned even if
src->results[i].index is -1, meaning that no interface is associated.
- In getaddrinfo() the source IP address used with the lo interface needs a
special case, as it can be any IP within 127.X.Y.Z.
