We've had flake in libdm_test for a long time, with no clear cause.
Lately however it has become particularly reproducible when running
the UeventAfterLoadTable test in isolation, and thus we've identified
the root cause.
uevents for device-mapper are fired when the sysfs node is added, but at
that time, the "dm" subnode has not yet been added. The root node and dm
node are added very close together, so usually it works, but sometimes
ueventd is too fast.
Instead of relying on sysfs, query the uuid/name node directly from
device-mapper.

When booting up, Android can boot into one of three modes: normal,
recovery, and charger mode. The set of modules that should be loaded
during first stage init in each mode can differ, which is why init
reads the list of modules to load from modules.load.recovery when
booting into recovery, and modules.load otherwise.
This means that init will read the list of modules to load during first
stage init from modules.load even when booting into charger mode. This
is not ideal, as it causes modules that need to be loaded during
first stage init only when booting into charger mode to also be loaded
during first stage init of normal boot, which can degrade boot time.
Thus, add support for reading modules.load.charger, which contains the
list of modules that need to be loaded during first stage init when
booting into charger mode.

For many years, services declaring "console" would only be started if the
console device specified by androidboot.console= was present under /dev.
However, they would also be started if the /dev/console node existed.
This fallback causes problems with newer GKI kernel images which now
hard-code "console=ttynull" via CONFIG_CMDLINE, which essentially means
/dev/console always exists, even though this console points nowhere.
It also causes problems on devices where the androidboot.console was not
the same as the kernel dmesg console ("console="), such as cuttlefish,
because those platforms could not simultaneously enable kernel logging
but disable the interactive serial console feature. The framework just
assumed both would be muxed on the same serial port. Cuttlefish had a
workaround, to use "androidboot.console=invalid" to avoid the fallback,
but this doesn't work on devices which still want to mux the kernel logs
and interactive serial console.
This change resolves the issue in a better way, by introducing a new
boolean property called "androidboot.serialconsole". Setting this to "0"
will disable the console services, regardless of whether the
/dev/console or /dev/${ro.boot.console} devices exist. Older kernels
and bootloaders don't need to set this and can rely on the old behavior
in init, but bootloaders booting newer kernels must set it to avoid the
"performance is impacted" message due to console services being started.

There can be more than one fstab entry of system partition.
For example, the filesystem of one entry is ext4 and another is erofs.
system /system ext4 ro wait,slotselect,avb=vbmeta_system,logical,first_stage_mount,avb_keys=/avb/q-gsi.avbpubkey:/avb/r-gsi.avbpubkey:/avb/s-gsi.avbpubkey

If both filesystems of system and system_ext paritions are erofs,
only the ext4 fstab entry will be returned by GetEntryForMountPoint,
and system_ext cann't be mounted.
So we need to return both of the fstab entries and try all of them.

If a service that runs under root doesn't have the capabilities field in
it's definition, then it will inherit all the capabilities that init
has.
This change adds a linter to detect such services and ask developers to
explicitly specify capabilities that their service needs. If service
doesn't require any capabilities then empty capabilities fields should
be added in the service definition.
The actual access control list on what capabilities a process can use is
controlled by the SELinux, so inheriting all the init capabilities is
not a security issue here. However, asking services to explicitly
specify the capabilities they need is a good defense-in-depth mechanism.
So far this linter only checks the services on /system partition.
All currently offending services are added to the exempt list. I will
work on fixing some of them in the follow-up changes.

process_cgroup_empty_ is used to indicate that a service is already
killed or not. If cgroup support lacks, services cannot be killed
because process_cgroup_empty_ is always true.
This change fixes it by not assigning process_cgroup_empty_ as true.
Instead, make KillProcessGroup send signals even when cgroup is
disabled. Also DoKillProcessGroupOnce() is updated so it returns a number of killed processes, excluding already dead processes. This behavior agrees with its name (DoKillProcessOnce), and it prevents regression upon missing cgroups, because kill(-pgid) will always
"succeed" so KillProcessGroup will loop even when all processes are
already dead.

Multiple tests in CtsInitTestCases, e.g. RebootTest#StopServicesSIGKILL,
can trigger the following race condition:
* A service is started. This involves calling fork() and also to call
RunService() in the child process. RunService() calls setpgid().
* Service::Stop() is called and calls KillProcessGroup().
KillProcessGroup() calls kill(-pgid, SIGKILL) before the child process
has called setpgid(). pgid is the process ID of the child process. The
kill() call fails because setpgid() has not yet been called.
Fix this race condition by adding a setpgid() call in the parent process
and by waiting from the parent until the child has called setsid() if a
console is attached.

Prepare for adding more code in the parent process that depends on
whether or not a console is required.

Make the code easier to read by introducing symbolic names for the
constants used by Service::Start() for communication between the parent
and child processes.

Change setpgid(0, getpid()) into setpgid(0, 0). This patch removes one
system call but does not change the behavior of the code. From the
setpgid() man page: "If pgid is zero, then the PGID of the process
specified by pid is made the same as its process ID."
