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.

In the publish function, the variable mAccumulate_pub is used to log
disk performance. However, the variable mAccumulate is used to log disk
stats. The variable mAccumulate is only populated during a stall event.
The publish function is used to log disk stats on a periodic timer,
therefore, it should not rely on stall events to log stats. Instead,
it should rely on the appropriately named mAccumulate_pub variable.

During verification, update-engine will invoke
SnapshotMap() and Unmap() for every partition verification.
Post Unmap(), update-engine immediately invokes Map()
for next partition. This is a narrow window wherein, daemon
from previous unmap() is still present and init hasn't
terminated it. Thus, when next MapSnapshot() is invoked,
Connect() fails as init may end up terminating the service.
Wait for the daemon to fully terminate and exit
when Detach() is invoked.

Improve the readability of this function by splitting it.
This CL includes the following behavior changes:
- If changing the directory owner and/or mode fails for /sys/fs/cgroup,
this is considered as a fatal error instead of something that should
only fail if "Optional" has not been set.
- If mounting the v2 cgroup controller fails, this is considered as an
error.
- Activating/mounting a cgroup controller only fails if the controller
has not been marked as optional.
