Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags
This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags. A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs
We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them. This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

__ANDROID_APEX__ was defined with the name of apex module.
-D__ANDROID_APEX__=com.android.foo
But in this way, conditional compilation is not easy since comparing
macro's string value is not supported in C/C++.
(There's no usages of this value in source tree.)
In most cases, modules can check if __ANDROID_APEX__ is defined to see
if they are compiled for apex.
For modules which should behave differently according to which apex they
are included, they can check __ANDROID_APEX_<NAME>__.

With __ANDROID_APEX_<NAME>__ definition, native modules may have
different behavior when it is built for a specific apex module.
Previously, the name is passed as value of definition __ANDROID_APEX__
like -D__ANDROID_APEX__=com.android.foo. But it is difficult to do
conditional compilation with it.
Now, since the name is incorporated into definition itself, it gets
easier to set #ifdef condition.

The NDK is built like this. Having it for app builds within the Android
build system allows us to distinguish platform code from app code.
This is specifically to distinguish AIDL interfaces using libbinder_ndk.
'myBinder-ndk_platform' libs will use additional functionality that
'myBinder-ndk' libs won't use (in the future, these may be separate
variants with the same name, see b/121157555).

Clang derives the value of __ANDROID_API__ from the triple these days. In a

A module can be built multiple times when it is referenced from one
or more APEXes. Sometimes, it is required for the module to behave
differently depending on the context; e.g., do A when built form
APEX M, do B when built for APEX N, and do C when built for platform.
The idea is to have a macro __ANDROID_APEX__ which is set to the
name of the apex that the module is built for. It is undefined when
the module is built for platform.

Not all projects can be built when their base directory (the
directory containing the Android.bp file) is automatically included.
For example, external/jsoncpp has a file named version, which will
override the standard library's <version> header.
It would maybe be reasonable for this to be on by default, but many
projects in the tree currently depend on this behavior.

From now on, a c++ shared library can be built only with adding
".sysprop" description file to srcs. Sysprop library generator will
automatically generate a .cpp and .h files, and the header file will be
exposed to any clients linking against the shared library. For the full
schema of description file, see system/tools/sysprop/sysprop.proto.
Bug: 80125326
Test: 1) write a .sysprop description file.
2) create cc_library_shared and add description file to srcs.
3) create another module, link against library of 2), include generated
header, and access generated sysprop functions
4) see compile succeeded.

The AIDL code generator can now include trace code in every generated
AIDL call. We don't want to enable this by default for all interfaces
for two reasons:
1) Potential performance overhead
2) For Java targets, the code depends on @hide APIs in android.os.Trace,
and I haven't found a clean way to determine whether a target is
allowed to use @hide stuff in the SDK. LOCAL_PRIVATE_PLATFORM_APIS
is almost it, but it's not set for the core framework (which is
exactly one of the things we'd like to trace).

Building a static library for the NDK only requires that the NDK
headers be available. Currently, A module with both
`static_ndk_lib: true` and `sdk_version: something` will have a cyclic

libraries.
