db1ea34748 Implement some of the missing LFS64 support.
This gives us:

* <dirent.h>
  struct dirent64
  readdir64, readdir64_r, alphasort64, scandir64

* <fcntl.h>
  creat64, openat64, open64.

* <sys/stat.h>
  struct stat64
  fstat64, fstatat64, lstat64, stat64.

* <sys/statvfs.h>
  struct statvfs64
  statvfs64, fstatvfs64.

* <sys/vfs.h>
  struct statfs64
  statfs64, fstatfs64.

This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

f8fcfbc85a Move away from the __ARCH_WANT_SYSCALL_NO_AT system calls.
Modern architectures only get the *at(2) system calls. For example,
aarch64 doesn't have open(2), and expects userspace to use openat(2)
instead.

16d1af167f libc: add limited FORTIFY_SOURCE support for clang
In 829c089f83, we disabled all
FORTIFY_SOURCE support when compiling under clang. At the time,
we didn't have proper test cases, and couldn't easily create targeted
clang tests.

This change re-enables FORTIFY_SOURCE support under clang for a
limited set of functions, where we have explicit unittests available.
The functions are:

* memcpy
* memmove
* strcpy
* strncpy
* strcat
* strncat
* memset
* strlen (with modifications)
* strchr (with modifications)
* strrchr (with modifications)

It may be possible, in the future, to enable other functions. However,
I need to write unittests first.

For strlen, strchr, and strrchr, clang unconditionally calls the
fortified version of the relevant function. If it doesn't know the
size of the buffer it's dealing with, it passes in ((size_t) -1),
which is the largest possible size_t.

I added two new clang specific unittest files, primarily copied
from fortify?_test.cpp.

I've also rebuild the entire system with these changes, and didn't
observe any obvious problems.

b24c0637d0 libc: Introduce __errordecl()
Define __errordecl and replace __attribute__((__error__("foo")))
with __errordecl. Make sure __errordecl is a no-op on clang, as it
generates a compile time warning.

890c8ed6ef Fix builds where _FORTIFY_SOURCE is off.
Also add a more intention-revealing guard so we don't have loads of
places checking whether our inlining macro is defined.

cd587701c8 FORTIFY_SOURCE: add umask check
Verify that the call to umask makes sense. While this wouldn't
have detected bug 7094213 (because the low order bits were all zero),
it might detect other similar bugs.

ae2d5ba314 Add support for the utimensat(2) syscall to bionic.
The kernel has supported this syscall for quite some time now,
but bionic did not.  Now that there is a need for it, let's
add it to bionic.
