newlib: Don't use -fshort-enums

The upstream newlib build uses -fshort-enums for a few files.  This
is intended to reduce code size, and it's harmless because the enums
affected are not used in at any ABI boundaries, just inside private
functions.  But on ARM, using -fshort-enums marks an object with
attributes saying it's using a non-default ABI and the linker warns
about mixing objects with and without -fshort-enums.  The possible
performance/code-size benefit of -fshort-enums is negligible in the
NaCl context, and it's more important that SDK users not get these
confusing warnings at link time.  Some unrelated whitespace/filling
changes appear as fallout from re-running Automake.

ARM: Use SFI_BREG prefix on PLD instruction

The ARM validator has recently begun requiring sandboxing for
the base register in pld (prefetch) instructions.  The newlib
ARM assembly code includes some of these, so they need to get
the sandboxing treatment.

Use 'naclret' in x86 assembly code

This macro is now supplied by both the old and new toolchains in
different ways and with different definitions.  Using it for all
NaCl-flavored function returns makes the assembly code compatible
with both.

Move 'rep' prefixes onto instruction lines

We need 'rep' to be a prefix rather than a standalone instruction
for .bundle_align_mode to recognize it as part of a whole instruction
that cannot be split.

Avoid setjmp-dj.h include for __native_client__

The nest of conditionals in setjmp.h is already mostly irrelevant
for NaCl.  When __native_client__ is defined, we undefine the macros
set by previous conditional blocks and define them uniformly for
__native_client__ on any machine.

The wrinkle arose that if __i386__ is defined and __unix__ is not also
defined, it tries to include "setjmp-dj.h", which has not just macros
but its own typedef and declarations.  We never want to get that file
for NaCl.  While the old nacl-gcc compiler happens to avoid this because
it predefines __unix__, the next-generation compiler (so far) does not
predefine __unix__, so it was bitten.

Change-Id: I7c763c1017ca9f98bd75bc6ae2b925cefe791a9e

Provide sanity check that compiler defines __*_ENDIAN__

We expect all Native Client compilers to define either
__LITTLE_ENDIAN__ or __BIG_ENDIAN__, so make sure we get a
compilation error if one fails to.

Fix newlib configury for all nacl hosts to use -DMISSING_SYSCALL_NAMES

There is an arm-*-* pattern that matches and prevents the default pattern
from matching and adding -DMISSING_SYSCALL_NAMES, whereas for i?86-*-nacl*,
x86_64-*-nacl*, or le32-*-nacl*, that default case does match.  So we need
a generic *-*-nacl* pattern to match first so that we ensure we add the
necessary -DMISSING_SYSCALL_NAMES switch for all nacl builds.

Avoid duplicate symbol for _dummy_mallocr which seems to be a hack

Not sure sure why newlib is not suppressing the compilation of the files
in the first place.

Exclude newlib's malloc implementation

We are adding a better malloc implementation built in the native_client

Review URL: http://codereview.chromium.org/7604003

Stop flushing streams on every thread exit.

Instead flush+close all files on program exit.  This is now possible with _REENT
initialization that properly points to the _GLOBAL_REENT parts (wich in turn is
initialized strictly earlier than any _REENT).

Since significantly more locking is added, the performance may degrade, however,
the locks are expected to be brief and non-contended.  To avoid this extra
locking with __sinit_lock we could initialize _GLOBAL_REENT in
__newlib_thread_init(), but this requires more time investment.

newlib/libc/stdio/local.h: Added brief locking around access to __sdidinit.

newlib/libc/stdio/findfp.c: Initialize _GLOBAL_REENT before any other _reent
  gets initialized, make the code look more alike in _REENT_SMALL and
  non-_REENT_SMALL cases.  The _REENT_SMALL has not been tested with NaCl.
  Changing the lock order in __sfp() to avoid a potential deadlock: our lock
  order is: __init_lock and then possibly __sfp_lock.

newlib/libc/stdio/fwalk.c: Make sure _fwalk* always traverses an initialized
  structure.

newlib/libc/reent/impure.c: Removed unnecessary cleanup and initialization.

Review URL: http://codereview.chromium.org/7582011

Let _REENT initialize lazily under proper locking.

This removes the race condition on reading _GLOBAL_REENT->__sdidinit that could
be modified simultaneously from another thread.

We are flushing all streams on every thread exit with _cleanup_r(_REENT) because
it does not work to do so from exit.c.  To be investigated.

Force int32_t to be int instead of long

If both int and long are 32-bit, newlib intentionally prefers long over int.
Force the opposite for nacl.
