User-visible instances of xdr_ops always seem to be allocated statically, and
don't need unpoisoning. Also, it's size differs between platforms.

Move fflush and fclose interceptors to sanitizer_common.
Use a metadata map to keep information about the external locations
that must be updated when the file is written to.

These interceptors require deep unpoisoning of return values.
While at it, we do the same for all other pw/gr interceptors to
reduce dependency on libc implementation details.

Some build environments are missing the required headers.
This reverts r200544, r200547, r200551. This does not revert the change that
introduced READWRITE ioctl type.
llvm-svn: 200567
Also rename internal_sigaction() into internal_sigaction_norestorer(), as this function doesn't fully
implement the sigaction() functionality on Linux.
This change is a part of refactoring intended to have common signal handling behavior in all tools.

struct stat defined in <asm/stat.h> is incorrect for x32. <asm/stat.h>
is included to get struct __old_kernel_stat. But struct __old_kernel_stat
isn't used for x86-64 nor x32. This patch includes <sys/stat.h> instead
of <asm/stat.h> and comments out size check of struct __old_kernel_stat
for x86-64.

by their authors.
This may break builds where others added code relying on these patches,
but please *do not* revert this commit. Instead, we will prepare patches
which fix the failures.
Reverts the following commits:
r168306: "[asan] support x32 mode in the fast stack unwinder. Patch by H.J. Lu"
r168356: "[asan] more support for powerpc, patch by Peter Bergner"
r196489: "[sanitizer] fix the ppc32 build (patch by Jakub Jelinek)"

Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time
assertions. This makes the dependency on the headers test-only and would allow
switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).

This header has not been supported at all for the last 2 major OS X releases.
Removed its include and the capture of related symbols.
