Patches applied to glibc-2.19

Please include a change to this file with each patch, *and* each
subsequent modification of the patch.  Do NOT combine patch
checkins, keep them separate.

Append new entries to the end of this file. Each entry shall include:
 * The list of files modified by the patch,
 * The status of the patch. Should be one of:
   - already upstream (indicate upstream revision),
   - not yet upstream, or
   - google-local (not applicable upstream).
 * The local 'owner' responsible for the patch, and
 * A description of the patch (preferably including bug numbers).

Please include entries for both local patches and for patches which
have been checked in to (or back-ported from) the upstream sources.
When checking in changes made upstream, add an entry to this file but
DO NOT add entries to the GNU ChangeLog files.

  For b/2832143 and b/10385480, add a stub libnsl library as an add-on, to
  replace the libnsl removed in the previous change.  Although we do not use
  libnsl normally, we have precompiled third-party binaries that need to
  dynamically link to it, and this stub satisfies that need.

  (ppluzhnikov, google-local)

include/alloca.h
  Set __MAX_ALLOCA_CUTOFF to 8kb to avoid stack overflow, as described in
  b/2425017.  The stack protection in //google3/thread/thread.cc creates a
  large stack with only 64kb of remaining space, which the upstream alloca

  Disable gcc's __warn_unused_result__ attribute in glibc headers when
  _GOOGLE_FORTIFY_SOURCE_NO_WARN_UNUSED_RESULT is specified, even if
  _FORTIFY_SOURCE is set.  Some google3 code does not compile when this
  attribute is set on some glibc functions.

stdio-common/print_fp.c

  Effectively revert an upstream patch to print signs on NaN values.  This

  frame pointers.
  Forward-ported from cl/51440285 (from cl//54512-p2).
  Note: this is redundant with http://cr/62476718 that builds entire glibc
  with -fno-omit-frame-pointer, but I am forward-porting it anyway in case
  we decide to revert cr/62476718 later.

include/features.h
  Allow suppressing the definition of __USE_FILE_OFFSET64 by defining
  SUPPRESS_USE_FILE_OFFSET64. As large file types match the default
  types, this is irrelevant in Google's depot, but leads to different type
  signatures for functions that are problematic with C++ modules.
