Open development for 2.20
Avoid comma operator warnings.
Remove am33 port.

This patch removes the am33 port (no other port #includes any files
from it), as previously discussed (see
<https://sourceware.org/ml/libc-ports/2014-01/msg00046.html>).
Move shared sysdeps files from alpha to arm.

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.
Move arm from ports to libc.

I've moved the ARM port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply

git mv ports/sysdeps/arm sysdeps/arm
git mv ports/sysdeps/unix/arm sysdeps/unix/arm
git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm

and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.arm similar to that at the top of
ChangeLog.powerpc.  There is deliberately no NEWS change, as I think
it makes the most sense to put in a general note above all ports
having moved if we can achieve that for 2.20.

Tested that disassembly of installed shared libraries for arm is the
same before and after this patch, except for data (not instructions)
in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the
path by which that file is found, and so by which it appears in the
assertion message, changes as a result of the move).

	* sysdeps/arm: Move directory from ports/sysdeps/arm.
	* sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm.
	* sysdeps/unix/sysv/linux/arm: Move directory from
	ports/sysdeps/unix/sysv/linux/arm.
	* README: Update listing for arm-*-linux-gnueabi.

ports/ChangeLog.arm:
	* sysdeps/arm: Move directory to ../sysdeps/arm.
	* sysdeps/unix/arm: Move directory to ../sysdeps.arm.
	* sysdeps/unix/sysv/linux/arm: Move directory to
	../sysdeps/unix/sysv/linux/arm.
Fix whitespace in ARM files to allow move.

tzselect: stop requiring ksh

tests: unify fortification handler logic

We have multiple tests that copy & paste the same logic for disabling the

tst-backtrace4: expand output even on failures

When debugging failures in this test, it's helpful to see as much output
as possible.  So rather than returning immediately, let the code run as
far as it can.  We still mark failures as soon as they happen.

Remove THREAD_STATS.

Deduplicate setenv.

Setenv contained a code path that was redundant as it could be handled
in general case.
