The python interpreter will by default add the directory of
the entrypoint script to the beginning of sys.path. This
can be disabled in python 3.11+ (which is not released yet)
using the PYTHON_SAFE_PATH environment variable or the -P flag.
As a workaround to have this behavior in older python versions,
we can make an __soong_entrypoint_redirector__.py file at the
root of the zip file that is the entrypoint, and then that
file will redirect to the real entrypoint.
This brings non-embedded-launcher python modules closer to
the embedded launcher version. The embedded launcher binaries
already act like this because they start at an __main__.py file
at the root of the zip file.

stub_template_host.txt added all the top-level modules to the
PYTHONPATH, which isn't correct, and caused absl.logging to
override the built-in logging module.
Removing this also makes it more consistent with python binaries
built with embedded_launcher: true. embedded_launcher: true
binaries don't add the top-level modules.

When multiple os/arch variants are supported, java_test_host could not
find a matching arch due to java having arch:common, whereas native
binaries support a specific architecture. This change adds the property
`data_native_bins` in order to support binaries with the appropriate
os/arch variants.

android/soong/common was renamed to android/soong/android long
ago, but the pctx package path was still "android/soong/common".
This required all users of rules defined in android/soong/android

pctx.Import("android/soong/common").

Soong doesn't wrap everything in bash, but relies on the ninja default
of /bin/sh. We should probably improve that in the future, but for now,
just fix the build.
On Mac, /bin/sh and /bin/bash are both bash, but /bin/sh implies `set -o
posix`, and ignores the `-n` flag.

The zip file format does support scripts/programs prefixed to the
archive, though many of the offsets are supposed to start from the
beginning of the file. Some tools (python and zipinfo) are able to
read zip files with arbitrary prefixes, but others (libziparchive and
zipdetails) fail.
So pass the file to prefix onto the zip file into merge_zips so that we
can set the offsets from the real start of the file.

The root cause is we didn't check if the optionalpath is valid or not,
the registerbuildation function directly invoke the path var and
cause the invalid memory error. We just return if the launcher doesn't
exist.
The ctx.VisitDirectDepsWithTag() also handles allowmissingdependency so
we are ok if launcher doesn't exist.

The problem came from Python libraries doesn't know the information that
we enabled embedded_launcher (only Python binary knows about that). And
we can't simply remove runfiles dir for Python libraries since host

Now that android.ModuleContext does not include blueprint.ModuleContext
we can rename android.ModuleContext.ModuleBuild to
android.ModuleContext.Build without colliding with

build/soong simultaneously.

launcher.
For Python2, we bundle embedded launcher as bootstrapper within every
.par file. This feature is only enabled for linux_x86_64 for now. We
provide a user flag: hermetic_enabled within bp file. By default, Pyhon2
still use classic bootstrapping way to construct .par file and relys on
host interpreter. Once embedded_launcher is enabled, launcher will be
used to bootstrap .par file and execute user program.
For Python3, the launcher will be ready soon, and for now it still relys
on classic bootstrapping.
Test: Real example is used to test.

useful information like the exact variant name used by soong.

compatibilty check, version variations split, source file format check,
source/data file duplicate check.
