The derivation happens in the derive_microdroid_vendor_dice_node binary
which first_stage_init forks and execvs.
Since the derivation requires talking to the dice driver, its
initialisation is also moved to the first stage init.
The derivation happens before the microdroid vendor partition is
verified & mounted. This should be safe because the first_stage_init
will fail the boot if the verification of the microdroid vendor
partition fails.

Introduce SpawnImage() as a reusable single-argument wrapper around
posix_spawn(), to avoid having to manually manage the child process.
Note that Bionic currently doesn't return the errno from the child's
exec() call to the caller in the parent process, which may temporarily
hide errors such as ENOENT in first_stage_console until Bionic improves.
Also, this introduces a subtle change in behavior as the first_stage.sh
script is now passed directly to the loader, which will only properly
invoke the Shell if the file contains the right shebang.
Inline the call to RunScript() to hopefully make it simpler for readers
to track the lifetime of the various processes on different code paths.

From wait(2):
POSIX.1-2001 specifies that if [...] the SA_NOCLDWAIT flag is set for
SIGCHLD, then children that terminate do not become zombies and a call
to [...] waitpid() will block until all children have terminated, and
then fail with errno set to ECHILD.
As we call sigaction(SIGCHLD, { SIG_DFL, SA_NOCLDWAIT }), running
pid_t w = waitpid(pid, &status, 0);
LOG(INFO) << "..." << status << " " << w << " " << errno;
shows that the calls consistently return (status=0, w=-1, errno=ECHILD).
Therefore, clarify the parent code by prefering wait(2) over waitpid(2),
as SA_NOCLDWAIT makes the kernel ignore the passed PID, and stop logging
the irrelevant status, to avoid confusion when the logs say the exit
status was 0 but the child actually returned an error.

If the /first_stage.sh is not present on the system, the child process
which attempted to execv() ends up returning from the function along
with its parent, which can be seen in early logs e.g.
[ 10.747576][ T51] init: Attempting to run /first_stage.sh...
[ 10.757371][ T52] init: unable to execv /first_stage.sh, returned -1 errno 2
[ 10.767527][ T52] init: unable to execv, returned -1 errno 2
[...]
[ 10.789189][ T51] init: unable to execv, returned -1 errno 2
where both T51 and T52 end up executing the "rest" of StartConsole().
Instead, terminate the child if its execv() failed.

The test is not eligible for CTS. Reasons:
1. The init behavior does not directly affect app compat. App interact
with init only for the property service and that part is covered by
the Bionic test already.
2. This test doesn't run against the init binary installed on the
device. libinit where most of the init functionalities are
implemented is statically linked to this test binary. In other words,
this test is closer to a unit test for init.
3. This test is not compatible with Trunk stable where test and DUT are
built in different branches. The test depends on several (private)
libraries like libbase and libutils. Since the interfaces of the
libraries may have changed in the main branch, the test binary built
from the old test-dev branch may break.
This change does not remove the test. The test will still run as a unit
test during pre/post submit.
I didn't drop the `Cts` prefix from the name, because that requires
broader changes.

During PrepareSnapshotPartitionsForUpdate, we attempt to connect to
snapuserd with a 5s timeout, only to tell snapuserd to shutdown
immediately. If snapuserd isn't running, we will wait-out the whole 5
seconds. Change the logic to return early if socket_connect() calls
return ENOENT, indicating that snapuserd socket isn't used by any
process. This reduces allocateSpaceForPayload() time from 6s to 1s.

The android-4.14-stable and later kernels support the
FS_IOC_ADD_ENCRYPTION_KEY and FS_IOC_REMOVE_ENCRYPTION_KEY ioctls. This
has superseded the old way of adding fscrypt keys to the kernel, which
was to use the add_key() syscall to add keys to the "session" keyring.
On kernels that support the ioctls, Android doesn't use the obsolete
way. Since upgrading even just to Android 14 requires at minimum a
android-4.14-stable kernel (according to
https://source.android.com/docs/core/architecture/kernel/android-common#compatibility-matrix),
there is no need to support the obsolete way anymore.
Therefore, this commit removes the code from init that created a keyring
named "fscrypt" in the session keyring. It also removes the code that
created the session keyring itself, since the only reason that Android
even created a session keyring was just to hold the "fscrypt" keyring.
Flag: N/A for the following reasons:
- Removing obsolete code, which is fairly safe
- Very early code, so runtime flag cannot be used
- Even a build-time flag cannot be used, since init needs
recovery_available, which aconfig libraries do not support
