This patch prepares for moving arm from ports to libc (see overall
plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html>
and discussion of ordering starting at
<https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by
reversing the #include order between arm and alpha, so that arm can
move early as a test for the general pattern of moving architectures.
MicroBlaze files (that used the same alpha files) were made to include
the files directly from their new locations rather than indirecting.
Tested that disassembly of installed shared libraries for arm is the
same before and after this patch.
* sysdeps/unix/sysv/linux/alpha/msgctl.c: Move to
sysdeps/unix/sysv/linux/arm/msgctl.c and #include that file.
* sysdeps/unix/sysv/linux/alpha/semctl.c: Move to
sysdeps/unix/sysv/linux/arm/semctl.c and #include that file.
* sysdeps/unix/sysv/linux/alpha/shmctl.c: Move to
sysdeps/unix/sysv/linux/arm/shmctl.c and #include that file.
* sysdeps/unix/sysv/linux/arm/msgctl.c: Move from
sysdeps/unix/sysv/linux/alpha/msgctl.c instead of #include of that
file.
* sysdeps/unix/sysv/linux/arm/semctl.c: Move from
sysdeps/unix/sysv/linux/alpha/semctl.c instead of #include of that
file.
* sysdeps/unix/sysv/linux/arm/shmctl.c: Move from
sysdeps/unix/sysv/linux/alpha/shmctl.c instead of #include of that
file.
* sysdeps/unix/sysv/linux/microblaze/msgctl.c: Include
sysdeps/unix/sysv/linux/arm/msgctl.c instead of
sysdeps/unix/sysv/linux/alpha/msgctl.c.
* sysdeps/unix/sysv/linux/microblaze/semctl.c: Include
sysdeps/unix/sysv/linux/arm/semctl.c instead of
sysdeps/unix/sysv/linux/alpha/semctl.c.
* sysdeps/unix/sysv/linux/microblaze/shmctl.c: Include
sysdeps/unix/sysv/linux/arm/shmctl.c instead of
sysdeps/unix/sysv/linux/alpha/shmctl.c.
Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.

This patch introduces two new convenience functions to set the default
thread attributes used for creating threads. This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.
[BZ #15442] This adds support for the inverse interpretation of the
quiet bit of IEEE 754 floating-point NaN data that some processors
use. This includes in particular MIPS architecture processors; the
payload used for the canonical qNaN encoding is updated accordingly
so as not to interfere with the quiet bit.
This feature is specifically for the C++ compiler to offload calling
thread_local object destructors on thread program exit, to glibc.
This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're
defined is unloaded by the dynamic linker. The DSO is marked as
'unloadable' if it has a constructed thread_local object and marked as
'unloadable' again when all the constructed thread_local objects
defined in it are destroyed.
In bdd7898a58 we added self-definitions
of __isnan and friends in order to indicate specialized architecture
support, and avoid redefinitions within various generic math_private.h.
There is no generic math_private.h that concerns ldbl-128, and while
we provide __isnanl in the alpha math_private.h there's no need to
protect the function against redefinition.
