baae083e60 Compress precompiled python zips
When making this script deterministic we accidentally changed it so that
none of the entries in the output zip file were compressed. Re-add
the compression.

Adding the compression makes atest go from 67M to 34M, at the cost of
0.33s startup time instead of 0.28s.

5a8f533a29 Improve errors when compiling python code
Now a stacktrace involving precompile_python.py won't be shown,
and it will show all errors instead of just the first one.

c755fdbe8e Fix non-deterministic python compilation
This CL fixes timestamps for zip entries to a hardcoded value to ensure
deterministic zip archives across checkouts, not just for incremental builds.
The value chosen for the fixed date is the same as the one used by soong_zip.

Bug: b/322788229
Test: Ran a few builds and verified that mdate for zipped files are
fixed as well as the generated zip files have identical hashes.

55b7ba0645 Fix non-deterministic python compilation
Timestamps in pyc files and zip archives were causing cache misses in RBE.

Bug: b/322788229
Test: Ran a few local builds and verified improved cache hit rate for metalava actions.

5c503d1c43 Precompile python sources
This signifigantly improves the startup time of soong-built
python binaries. For example, running
`m apexer && time out/host/linux-x86/bin/apexer` gives
0.734s before this cl, and 0.094s after.

eb3a900c5c Add flag to not add directory of entrypoint to sys.path
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.

af4b13dbe4 Add flag to not add top-level modules to PYTHONPATH
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.

bea0975f18 Fix embedded_launcher can't find files
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
Python mode need this.

184901135c Revert "Revert "Revert "Revert "Add path interposer""""
This reverts commit 09f4540d66.

Fixes the raw call to net.Listen in the tests to go through the listen()
helper and use the long socket path fallbacks.

Removes the use of timeouts from the tests -- the behaviors being tested
did not rely on timeouts, so removing them will reduce the flakiness if
the build is heavily loading the machine at the same time the test is
running.

Also fixes some potential nil pointer dereferences.

09f4540d66 Revert "Revert "Revert "Add path interposer"""
This reverts commit c59a92cb1a.

Reason for revert: tests are broken with long OUT_DIRs
They're directly calling net.Listen, and not using the fallback
for long socket names.

c59a92cb1a Revert "Revert "Add path interposer""
This reverts commit 96c957ae20.

Fixes issues on some machines where the socket in TMPDIR ended up with a
unix domain socket pathname over 107 characters long, which Go will
reject due to underlying limitations in the system calls. If this
happens, we'll fall back to opening the directory, then using
/proc/self/fd/#/<file>, or manually creating a similar symlink in /tmp.

Also fixes some issues on Mac where os.Executable returns the symlink
instead of the underlying file, sending a message over a unix domain
socket will block if the reader isn't reading, and sandboxing was
preventing us from running `ps`.

a14704c12b Add path interposer
This will allow us to track (and eventually limit) the commands that the
build references via $PATH. These are mostly implicit dependencies on
the host system -- for Linux, we assume something similar to Ubuntu
14.04 with a few extra packages, but this will let us better define
that.

This will not catch uses of tools with absolute paths (/bin/bash, etc),
but most uses shouldn't be relying on absolute path names anyways.

Adds ~400ms on the first startup, ~140ms on subsequent runs, and
overhead of a few ms for every forwarded execution.

db0b9a3cf3 Supported python build in host side.
The base module handles all the common functionalites, such as version
compatibilty check, version variations split, source file format check,
source/data file duplicate check.

The library/binary module focuses on how to generate binary build actions,
such as setting up stub script, zipping, filling in __init__.py in
runfiles dir tree.
