48501af98f AArch64: Fix flock64 for LP64.
On LP64 systems F_GETLK64, F_SETLK64 and F_SETLKW64 definitions should
map onto the F_GETLK, F_SETLK and F_SETLKW definitions, respectively.
LP64 also doesn't have a struct flock64.

950a58e24d Add stpcpy/stpncpy.
Add tests for the above.

Add the fortify implementations of __stpcpy_chk and __stpncpy_chk.

Modify the strncpy test to cover more cases and use this template for
stpncpy.

Add all of the fortify test cases.

This is an implementation in the style of the rest: char == byte.

when DNS configuration is supplied.

205c7887ad Clean up reentrancy cruft.
The DNS copy of reentrant.h was unused, so remove it.

The strtod implementation can use the upstream-netbsd reentrant.h and
get a little closer to what was then upstream. (It's since been replaced
by gdtoa, and we'll have to follow at some point, but for now this doesn't
make anything any worse.)

ANDROID_CHANGES is (now) only used in the DNS code, so push the -D
down.

The <locale.h> change prevents an LP32 hack from leaking into LP64.

aa0ebdafc7 Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

3a9c5d66dc Fix <link.h>.
Also move some of the stuff that should be in <link.h> out of the
private "linker.h", to make it clearer that these are public API
known to gdb that we can't change.

9afe2884c7 Kill <machine/_types.h>.
Most of <machine/_types.h> was either unused, wrong, or identical across
all 32-/64-bit architectures.

I'm not a huge fan of <sys/_types.h> either, but moving the bits we need
up into there is a step forward.

8d60cc6316 Use __inline__ for fortify.
libunwind has #define inline /* empty */ which breaks our fortified headers.
glibc uses __inline but our BSD-derived headers often override that. __inline__
is the third alternative understood by GCC that -- as far as I know -- neither
the C library itself nor third-party code tries to mess with.

323d4b6f68 Add "__noreturn" to assert and assert2
These functions should print assertion violation messages and then
call abort(). They do really not return control flow afterwards.
Consider the declaration of the similar __assert_fail from glibc:

extern void __assert_fail (const char *__assertion,
                           const char *__file,
			   unsigned int __line,
                           const char *__function)
     __THROW __attribute__ ((__noreturn__));

Bionic has __noreturn defined in sys/cdefs.h to be that GNU
noreturn attribute.

This patch has a practical value. Consider the following function:

void check(void* ptr) {
  assert(ptr != NULL);
}

Without this patch applied, gcc (and presumably clang) shows even in
debug mode:

warning: unused parameter 'ptr' [-Wunused-parameter]

In release mode, NDEBUG is defined and assert() becomes a no-op, as
one should expect. Thus, the warning is shown correctly then.

Another code sample:

float array[2];
int i = 3;
...
assert(i < 2);
array[i] = 0;

gcc says,

warning: array subscript is below array bounds [-Warray-bounds]

In other words, without noreturn attribute, assertions do not
allow a compiler's static analyzer to properly understand
the preconditions.

This patch adds trivial implementations of the missing sys headers
needed by strace. All strace needs are the constants and structures,
so this is enough for now. We can come back and add the functions
if/when we ever need them.

0f461e35f6 Fix <sys/resource.h>.
The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.

We need the rlimit64 functions to be able to build strace 4.8 out of the box.
