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.

Some guy on the internet complained that dnscap doesn't build out of the box.
Now it does.

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)

_resolv_set_nameservers_for_net() so far did not update the search
paths, unless the servers changed as well.

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.
