* The code between the two if-statements does not queue actions.

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
system /system erofs 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.

If UnregisterHandler() is called from inside a handler for an event that
has not yet been processed then that will result in a use-after-free.
Fix this by passing file descriptors to epoll_ctl() instead of pointers
to map elements.

Review note: Original change was a p-o-c by agl in
https://r.android.com/2094350 which I think is actually
production quality. I'm just taking it over so that he doesn't
get spammed by any review comments as that's not a good use
of his time.
Needed for the hardware entropy daemon (see bug).
Original commit message:
If one needs to create a service that synchronously starts listening on
a socket then there are currently no good options.
The traditional UNIX solution is to have the service create the socket
and then daemonise. In this situation, init could start the service with
`exec_start` and yet not block forever because the service forks and
exits. However, when the initial child process exits, init kills the
daemon process:
> init: Killed 1 additional processes from a oneshot process group for
> service 'foo'. This is new behavior, previously child processes
> would not be killed in this case.
Next, there is a `socket` option for services and (although the
documentation didn't nail this down), the socket is created
synchronously by `start`. However, init doesn't call `listen` on the
socket so, until the service starts listening on the socket itself,
clients will get ECONNREFUSED.
This this change adds a `+listen` option, similar to `+passcred` which
allows a socket service to reliably handle connections.
Bug: 243933553
Test: Started prng_seeder from init using the new listen flag

Services created during new tests weren't properly cleaned up after tests. It caused slowdown of subsequent tests as described in b/244486404.
This change kills/terminates services after test with apex services.
To provide some context, original change is at https://android-review.googlesource.com/q/topic:vapex_stop_service. The issue was discovered by android test monitor and filed as a P0 bug.

extra_free_kbytes.sh accepts a parameter representing the number of KB
to add to low and high watermarks. It adds this margin to the current
watermark levels, however this is not how /proc/sys/vm/extra_free_kbytes
knob that it replaces used to work. The old knob would add the margin
relative to the original and not the current level of the watermarks.
Change extra_free_kbytes.sh to add the specified margin to the original
watermark levels to act as correct replacement of the old knob.

However, in some cases the first-stage-init comes from a GKI prebuilt
boot.img and doess not create the required folder (see for example
b/217677967), resulting in bugs like b/244793900.
I modified the selinux.cpp code to create the /dev/selinux folder if it

mmap_rnd_compat_bits is for address space randomization of 32-bit
applications on 64-bit system. Configuring it is not only unnecessary
for 64-bit "only" builds, but also can cause a boot failure if the
kernel is built without CONFIG_COMPAT which is the case for Microdroid.

supported and if not, don't configure it, but mmap_rnd_bits.

These props are supposed to be used by apexd when installing an apex
without reboot. During the installation, apexd will unmount the current
one and mount the new one. Since the path and its contents will be
replaced, anything loaded from the apex should be unloaded before
unmounting. After apexd mounts the apex again, then init should re-read
.rc files from the apex.
This change only addes required properties:
- ctl.apex_load <apex_name>
- ctl.apex_unload <apex_name>
- init.apex.<apex_name> = loaded | unloaded

Now that emulated FBE is no longer supported, there is no longer any
distinction between native FBE and emulated FBE. There is just FBE.
Referring to FBE as "fscrypt" is also poor practice, as fscrypt (the
Linux kernel support for filesystem-level encryption) is just one part
of FBE, the Android feature.
Therefore, rename fscrypt_is_native() to IsFbeEnabled().

If booting with debug ramdisk (ro.force.debuggable is true), override
the persistent property "persist.sys.usb.config" to always enable adb.
This ensures a consistent debug experience. The developer can expect
that after debug ramdisk (debug boot image) is flashed,
1. Device is rootable with (adb root)
2. adb is enabled automatically
3. no-auth (if $ADB_VENDOR_KEYS is used)

When a process is started as a native service,
oom_score_adj is set to -1000 so that processes
are unkillable by lmkd.
During boot, snapuserd process is not started as a service;
hence, we need to set the oom_score_adj explicitly else in
the event of low memory situation, lmkd can kill the
process thereby device can never boot.
