We don't support anything other than Clang and GCC, and we don't support
GCC earlier than 4.9.
Move the various synonyms for __attribute__(__whatever__) together.
Fix a __STDC__VERSION__ (for __STDC_VERSION__) typo.
Drop support for BSD _ANSI_SOURCE and _C99_SOURCE; there's enough confusing
nonsense here already, and plenty of other ways to ask for obsolete standards.
There are plenty more problems here -- what I really want to do is rationalize
our treatment of __STDC_VERSION__ -- but let's get some of this easy stuff
out of the way first.

bionic doesn't have an implementation for this function, but neither
does the kernel. cachectl has existed in the kernel as a stub that
returns ENOSYS for over a decade.

We have an explicit link map now, so we don't need a separate copy of libstdc++
that's built with -fvisibility=hidden.

These directories all have Android.bp files that are always used now,
delete the Android.mk files.

The typedefs for __u64 and __u32 aren't in scope in this file, so
switch fields declared with these to use the matching underlying type.

Add a new document that describes the previous version of malloc debug.
Add a small update to the current documentation to indicate it only
applies to N and later.

There's no change to the generated stubs, because the script only cares
that this is a pointer type, not what it's a pointer to.

Also clean up some near-miss copyright headers in libm, and remove
some cruft in <grp.h>/<pwd.h> that the script can't automatically
ignore since we stripped all the tabs in those files.

When building with soong Android.mk files are ignored in directories
that have Android.bp files. Only parts of bionic have been converted to
Android.bp files, including some directories that have subdirectories
with Android.mk files.
Add Android.soong.mk files to include subdirectories to any directory
that has an Android.bp file but also has subdirectories with only
Android.mk files.

Move everything to where it should be.
Along the way, we lose <net/ethertypes.h>. glibc only has a handful of these
types, and they're all in <net/ethernet.h>, not <net/ethertypes.h>. I've taken
the liberty of not including the AppleTalk ones, since it is 2016.
Also, <net/if_ether.h> should be <netinet/if_ether.h> (though with different
contents).

* Remove --exclude-libs ldflags (e29e99c51)
* Mips strlen check was inverted
* ARM specific libc changes only apply to the shared library
* Reorder libjemalloc and malloc_common to match Make's ordering (for
better binary diffing)

They are intended for platform use only and we shouldn't have them
in the public header file.

It's been deprecated long enough, and nothing left in the tree (except
code that isn't even built) is still using it.

* Allow clone where both the child function and stack are null. It's
obviously wrong to ask to call a function without a stack, but it's not
necessarily wrong to supply no stack if you're also not supplying a
function.
* Reimplement fork in terms of the clone function, rather than using the
clone system call directly.
This is intended as a step towards enabling use of pid namespaces.

This is now done by default in the build system.
The comments say don't do this, but we have linker scripts that
protect the few symbols we have to actually keep now.

http://clang.llvm.org/docs/AttributeReference.html#nonnull
_Nonnull is similar to the nonnull attribute in that it will instruct
compilers to warn the user if it can prove that a null argument is
being passed. Unlike the nonnull attribute, this annotation indicated
that a value *should not* be null, not that it *cannot* be null, or
even that the behavior is undefined. The important distinction is that
the optimizer will perform surprising optimizations like the
following:
void foo(void*) __attribute__(nonnull, 1);
int bar(int* p) {
foo(p);
// The following null check will be elided because nonnull
// attribute means that, since we call foo with p, p can be
// assumed to not be null. Thus this will crash if we are called
// with a null pointer.
if (src != NULL) {
return *p;
}
return 0;
}
int main() {
return bar(NULL);
}
Note that by doing this we are no longer attaching any sort of
attribute for GCC (GCC doesn't support attaching nonnull directly to a
parameter, only to the function and naming the arguments
positionally). This means we won't be getting a warning for this case
from GCC any more. People that listen to warnings tend to use clang
anyway, and we're quickly moving toward that as the default, so this
seems to be an acceptable tradeoff.

It's no longer used in the platform (including vendor code), and everyone
should be using <stdatomic.h> anyway.

* changes:
Remove nonexported _ns_flagdata from public header.
Add platform specific version tags.
Add __INTRODUCED_IN_FUTURE for unreleased APIs.
Add versioning information to symbols.
Some symbols appeared at different times between 32 and 64 bit. Add a
macro to represent this.

Future API levels aren't known (e.g. 25 could be a maintenance release
of N that doesn't contain any bionic updates), so use a placeholder
macro that we can find and replace with the actual API level before each
release.
