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.

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.

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.

As suggested here: https://android-review.googlesource.com/#/c/71267/
it may be used for x86_64 libunwind enabling.

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.

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.

glibc has no <sys/dirent.h>. If we do have to bring this back, we
should probably just have one file #include the other.

If glibc hadn't already done things this way round, I'd have
called the field sched_priority and the macro __sched_priority
since that would seem less likely to cause trouble, but glibc
source compatibility is probably more important.

Adds the TCPOPT_* constants from NetBSD. Note that the BSDs also have
TCPOPT_SIGNATURE, but Linux calls that TCPOPT_MD5SIG and glibc doesn't
have any corresponding constant yet, so let's wait until we see which name
wins out.

32-bit Android's dev_t was wrong too. We can't fix that without ABI breakage,
but we can at least fix 64-bit Android. And add tests.

This patch switches to using the uapi constants. It also adds the missing
setns system call, fixes sched_getcpu's error behavior, and fixes the
gensyscalls script now ARM is uapi-only too.

Even though code built with clang won't be fully fortified
and won't contain calls to our various helpers, binaries built
with GCC will.

This is a better solution than the old __warn_references because it's
a compile-time rather than link-time warning, it doesn't rely on something
that doesn't appear to be supported by gold (which is why you only used
to see these warnings on mips builds), and the errors refer to the exact
call site(s) rather than just telling you which object file contains a
reference to the bad function.
This is primarily so we can build bionic for aarch64; building libc.so
caused these warnings to fire (because link time is the wrong time) and
warnings are errors.
