$(shell) isn't particularly fast in Kati, and they have to be executed
both when reading the makefiles and determining whether the ninja file
needs to be regenerated.
Right now, the regen time is mostly hidden because we run them in
parallel. We've also configured it to ignore any commands that contain
"echo", "date", or the output directory. That happens to remove most
commands that contain side effects, so running them in parallel is fine.
But the side effects contain some important things, like the clean up
necessary when switching products. So I'm removing those filters, and
then we'll need to run the shell commands in sequence, since there will
be side-effects. That makes regen take longer though, so use pure-Make
implementations instead of $(shell) where possible.
This set of changes reduces aosp/master aosp_arm64-eng build $(shell)
usage and time by 2/3:
*kati*: func shell time: 3.135095 / 709
*kati*: func shell time: 1.067331 / 236

This shouldn't be necessary for most makefiles, since we add
$(LOCAL_GENERATED_SOURCES) to this already included, but for prebuilts
that aren't actually prebuilts (Soong modules), we need to pass
dependencies so that the generated headers are built before being used.

This was printing "error:", but not actually triggering an error.
Instead of trying to write a single line bash script to handle this,
move the actual check into python. This allows us to print all of the
errors for a single module before triggering the failure.
Also updates the warning format and the warn.py script to properly parse
these warning. Many of the java:sdk -> java:platform warnings are false
positives due to the lack of LOCAL_SDK_VERSION markings on prebuilts.
Individual tags can be marked as warnings now, which lets us check for
system libraries linking against vendor libraries (which won't work on
AOSP). I'm not sure this is a completely valid check, which one reason
that it's just a warning.
Test: m all_link_types (with some missing libs commented out)

We want to build things in CTS (things built against the NDK) with
integer overflow checks. Some projects in the tree also make explicit
calls to the overflow checked builtins, and those projects need to be
built with the NDK (external/dng_sdk is the specific example that
brought this up).

BUILD_HOST_static has been broken because I was stripping
-Wl,--start-group/-Wl,--end-group into a separate set of ldflags instead
of keeping them wrapped around some of the ldlibs. So don't pass some of
the build system flags through the ldlibs checker.

Native coverage is enabled by setting NATIVE_COVERAGE to true
and specifying a list of paths in the COVERAGE_PATHS
environment variable. Files are exported to a zip file in the

The output will be in the `m dist` results as soong_to_convert.txt, or
can be built using:
$ m $OUT/soong_to_convert.txt
The output is a list of modules that are probably ready to convert to
Soong:
# Blocked on Module (potential problems)
283 libEGL (srcs_dotarm)
246 libicuuc (dotdot_incs dotdot_srcs)
221 libspeexresampler
215 libcamera_metadata
...
0 zram-perf (dotdot_incs)
The number at the beginning of the line shows how many native modules
depend on that module.
All of their dependencies have been satisfied, and any potential
problems that Make can detect are listed in parenthesis after the
module:
dotdot_srcs: LOCAL_SRC_FILES contains paths outside $(LOCAL_PATH)
dotdot_incs: LOCAL_C_INCLUDES contains paths include '..'
srcs_dotarm: LOCAL_SRC_FILES contains source files like <...>.c.arm
aidl: LOCAL_SRC_FILES contains .aidl sources
dbus: LOCAL_SRC_FILES contains .dbus-xml sources
objc: LOCAL_SRC_FILES contains Objective-C sources
proto: LOCAL_SRC_FILES contains .proto sources
rs: LOCAL_SRC_FILES contains renderscript sources
vts: LOCAL_SRC_FILES contains .vts sources
Not all problems can be discovered, but this is a starting point.

Traditionally this has come from android/api-level.h, but with the

Any NDK shared libraries not in LOCAL_SYSTEM_SHARED_LIBRARIES weren't
being pulled from the generated libs before since we were only
filtering my_system_shared_libraries and even if we had filtered
my_shared_libraries they would have been rewritten to my_ldlibs.
* Filter my_shared_libraries for NDK generated libs as well.
* Stop rewriting NDK LOCAL_SHARED_LIBRARIES to my_ldlibs. Instead,
rewrite in the opposite direction just like we do for the platform.
* Move shared libs/ldlibs rewriting to before we filter NDK
libraries out of shared libs/system shared libs.

AUX is a new class, similar to TARGET
While TARGET defines toolchain for Application Processors
AUX is defining toolchains for arbitrary utility cores (DSPs, GPUs,
MCUs, etc). This allows building of non-android sources as part
of Android tree and avoid using prebuilts if source code is avaliable
