This seems to be obsolete BSD stuff, and the only references to it in the
tree are people #undef'ing it.

This fills out the defines that utmp.h normally offers on other systems

In particular, we don't need to record the peculiarities of every
version of GCC ever shipped. It just makes this file harder to follow.

The comment about "other stuff" referred to pre-uapi headers. Everything
in the current <linux/udp.h> should be exposed to userspace. The only
problem is that BSD and Linux use different names for the members of
struct udphdr. We can move the Linux udphdr out of the way and use an
anonymous union to get the best of both worlds. (Though unfortunately
this means that code that includes <linux/udp.h> directly instead of
using <netinet/udp.h> now won't have any definition of struct udphdr.
We've taken the stance in the past that you shouldn't include a linux/
header if there's a standard equivalent --- you should rely on us
transitively including it for you.)

MIPS and the rest of the world only disagree on the first two SOCK_*
constants, so restructure the #ifdef accordingly.
As a deliberate side effect, this fixes SOCK_DCCP being missing on
non-MIPS platforms.

bionic is built without _FILE_OFFSET_BITS=64, so internally regoff_t
was 32-bit on LP32, but code compiled with _FILE_OFFSET_BITS would
expect rm_so and rm_eo in struct regmatch_t to be 64-bit, leading to
confusion.

These are just based on the read/pread{,64} implementations with the
function calls and error messages adjusted as appropriate. The only
difference is that the buffer parameters are const.

It turns out that everyone's still getting PAGE_SIZE from <sys/user.h> via
<sys/ucontext.h> via <signal.h> anyway.
glibc has PAGE_SIZE in <sys/user.h> rather than <limits.h> so this part is
good. The bad part is that we have such wide transitive inclusion of
<sys/user.h>!

I'm removing the TODO on the assumption that being compatible with glibc
is more useful than BSD. The new internal "bionic_page.h" header factors
out some duplication between libc and the linker.

A __size_mul_overflow utility is used to take advantage of the checked
overflow intrinsics in Clang and GCC (>= 5). The fallback for older
compilers is the optimized but less than ideal overflow checking pattern
used in OpenBSD.

libchrome uses __USE_XOPEN2K8 to decide whether futimens is
available. That's perhaps not the best idea, but there are other
cases where we defined the same feature macros as glibc to aid
portability.

(cherry picked from commit f643eb38c3)
The NDK self-test issue64679-prctl failed to build because by default
clang3.6 builds in C11 mode, but the ifdef in the file 'uchar.h' hid the
required char16_t and char32_t declarations based on the GCC version,
which is declared as 4 by clang.
The ifdef is changed so that it is based on C version rather than a
compiler version. This way it is compatible with gcc 4, gcc 5 and clang
which are actually the only used toolchains.

We don't want to use <asm/ptrace.h> because (a) it'll drag in a bunch of
namespace pollution and (b) the registers should be "long double" for
userspace, not the kernel's uint128s. So just use a slightly different
name for our struct (which matches the traditional names for these structs
anyway).

The pthread_mutex_lock and pthread_mutex_unlock were allowed to
fail silently on L 32 bit devices when passed a NULL. We changed
this to a crash on 32 bit devices, but there are still games that make
these calls and are not likely to be updated. Therefore, once again
allow NULL to be passed in on 32 bit devices.

Adds a new _internal_ function. Provide a global serial number to
support more efficient private caching algorithms. This allows
to skip re-running the __system_property_find() call on misses until
there is a global change in the properties. This call is a read
barrier, the property data to be read following this call will be
read sequentially and up to date.
