I was curious to try r22 out today and it needed these small tweaks,
which should be compatible with r21d. I'll hold off on the actual
upgrade until r22 is out of beta.
Builds using the NDK compilers (r21d or r22 both) don't even need the
remaining --sysroot flag, but keeping it lets GOMA builds using Chrome's
compilers keep working.

This is an Android request for our public headers,
much like warning about unused parameters. See bug.
In general I've made two kinds of source changes:
1) more commonly, explicitly cast to the type which
is being implicitly cast to at head;
2) less commonly, flip signedness of a value we're
storing to match how it's used more smoothly.
Much of this is self inflicted inconsistent use of size_t, unsigned,
int, int32_t, uint32_t, etc. SkTArray is particularly tricky because
of its std::vector half-compatibility. E.g. resize() takes size_t,
but operator[] takes int. ¯\_(ツ)_/¯

In C++11 a user declared destructor still requires the compiler to
implicitly default the copy constructor and copy assignment operator,
but this is deprecated. Note that a user declared destructor suppresses
the move constructor and move assignment operator; a user declared
destructor exists if any '~Foo' method declaration appears inside
'class Foo' (even if defaulted); if the copy and move operations are the
same then copy operations that take 'const Foo&' will do fine double
duty as move operations.
Clang seems to have an issue with this warning, in that it does not
appear to distinguish between compiler defaulted and user defaulted
destructors. As a result, it does not always warn when it should.
There may yet be places in the code where a move operation is desired
but may be suppressed because the implicitly defaulted moves are not
declared because a destructor has been declared.
This wraps dawn and shaderc configs in 'third_party' so that their
headers will be included through '-isystem' in order to avoid the
warnings generated by including their headers.

GCC 9 warns about this pessimizing-move. It isn't clear why clang isn't
as well.
GCC 9 has a working redundant-move diagnostic. Clang has an old (C++11
style) redundant-move diagnostic which only warns when moving a
parameter. The GCC warning conflicts with Clang's
return-std-move-in-c++11, which we want to keep until we can drop
support for older compilers. So just disable redundant-move warnings
until we can remove return-std-move-in-c++11.
This change allows us to compile without warnings on gcc 9.3.0.

Unfortunately in clang 'deprecated' is both a set of warnings (at least
one of which we don't want) and a group of warnings (most of which we do
want). Leave the top level disabled, but re-enable all the warnings in
the group.
Most of the code changes are for the deprecated-copy diagnostic. In
C++11 implementing a copy constructor xor copy assignment operator
the default implementation of the other is still required to be the
default but is deprecated (the compiler can warn against doing this).
The idea is that if there was a need for a non-default copy constructor
or copy assignment operator then both should be implemented explicitly,
since it is unlikely that the default will do what is expected.
Note that the deprecated-copy-dtor has not yet been enabled as there
will need to be a lot more work to enable this diagnostic. Similar to
deprecated-copy, in C++11 when implementing a destructor the copy
constructor and copy assignment operator are still defaulted if not
declared, but this is also deprecated. The idea here is that if some
special handling is needed to destroy the object there is probably some
need to do something non-trivial when copying the object (or copying
should be disallowed).
Also, there are still some deprecated-declarations to clean up on
Android and Mac.

This CL has a complicated back story, but it's concrete change is
simple, just turning the warning on and converting a bunch of
return foo;
to
return std::move(foo);
These changes are exclusively in places where RVO and NRVO do not apply,
so it should not conflict with warnings like -Wpessimizing-move.
Since C++11, when you return a named local and its type doesn't match
the declared return type exactly, there's an implicit std::move()
wrapped around the value (what I'm making explicit here) so the move
constructor gets an opportunity to take precedence over the copy
constructor. You can read about this implicit move here under the
section "automatic move from local variables and parameters":
https://en.cppreference.com/w/cpp/language/return#Notes.
This situation comes up for us with smart pointers: a function declares
its return type as std::unique_ptr<Base> or sk_sp<Base>, and we return a
std::unique_ptr<Impl> or sk_sp<Impl>. Those types don't match exactly,
so RVO and NRVO don't come into play. They've always been going through
move constructors, and that's not changed here, just made explicit.
There was apparently once a bug in the C++11 standard and compilers
implementing that which made these copy instead of move, and then this
sort of code would do a little unnecessary ref/unref dance for sk_sp,
and would entirely fail to compile for uncopyable std::unique_ptr.
These explicit moves ostensibly will make our code more compatible with
those older compilers.
That compatibility alone is, I think, a terrible reason to land this CL.
Like, actively bad. But... to balance that out, I think the explicit
std::move()s here actually help remind us that RVO/NRVO are not in play,
and remind us we're going to call the move constructor. So that C++11
standard bug becomes kind of useful for us, in that Clang added this
warning to catch it, and its fix improves readability.
So really read this all as, "warn about implicit std::move() on return".
In the end I think it's just about readability. I don't really hold any
hope out that we'll become compatible with those older compilers.

Apply -fsanitize-recover=pointer-overflow to third_party code only.
I'm trying to keep Skia behaving the same, avoiding illegal nullptr+k:
- Add null check in SkJSON fast string path.
- Add null check (first alloc) and some comments to SkArenaAlloc.
- March an int index instead dst pointer in SkBase64.

With this change C++17 language features can be used in code that does
not need to be be included in client code (not in public headers or
the files they transitively include).
We haven't investigated the c++17ness of the standard libraries in use
by clients so proceed with caution on library features.
One thing discovered along the way: throw() in C++17 is now equivalent
to noexcept(true). Moreover, the noexcept-ness of a function is part of
its type in C++17. This means that if a header declares a function with
throw() and it is included in a cpp compiled with C++17 file it will have
a different type than if it is compiled in a file compiled with C++14 (or
earlier) and you can get linker errors. Here is a change we had to make
as a result of this:

With XCode 11 there is no more /usr/include directory. This
does not affect the XCode compilers, but does make goma compiler
break. This finds the system includes the same way that the iOS
builds currently do.
The gn_to_bp.py tool runs gn with target_os == mac, but host_os != mac.
In that case, the xcrun tool can not run, so make xcode_sysroot = "". This will
allow the xcode compilers to work when using the android.bp to build things.
TESTED:
builds on mac with and without goma

We've failed to get these bots to report where issues happen
any more finely than the name of the executable, which makes
them a real pain to fix when they go red.
We don't expect we'll be able to run cleanly in this mode for
long without bots enforcing it, so remove support from GN too.

If you just use the right compiler driver wrapper, recent NDKs automate
lots of the stuff we used to have to do ourselves.
Simplifying further, bump baseline ndk_api from 16 (Jellybean) on 32-bit
machines and 21 (Lollipop) on 64-bit to 21 across the board. This makes
using libc++ a lot easier, as it hooks into a bunch of APIs that were
added in 18 and 21. There's probably some way to work around this, but
the easiest thing is to just roll up.
Tested building {x86,arm}x{32,64} from a Linux host,
and running { arm}x{32,64}.
Kind of flailing around in later CLs trying to get linking not to hang
on Windows. I figure it's got something to do with lld?

Something's trying to link libc++.so by default,
so ask it to link libc++.a with -static-libstdc++.
Either way, the linker can't find libc++ without
adding another library directory path.
I think both changes should be harmlessly ignored
before r20.
