Fix a deadlock that happened when a reader/writer thread released a
transport while the hotplug thread attempted to handle a device
disconnection. Decrementing a transport refcount to zero would hold the
global transport mutex and attempt to take the usb handles mutex, while
the hotplug thread would hold the usb handles mutex and try to call
unregister_usb_transport, which would attempt to take the global
transport mutex.
Resolve this by making transport_unref not take the global transport
mutex.

libprocessgroup kills the cgroup associated with a given pid and uid,
but not the POSIX process group associated with it. This means that
to kill both, two of the same signals must be sent, which may cause
some issues.
This change kills all POSIX process groups whose group leaders are
found within a cgroup. It only then kills processes in the cgroup
that are not part of the POSIX process groups that have been killed.

Current first stage mount only allows three mount points: system, vendor
and/or odm. This was introduced by project Treble to mount those
verified partitions early. However, there might be some other custom
partitions needs to be mounted early as well. This CL removes the
restriction and does first stage mount for whatever specified in
fstab-dt.

If a device is unplugged while it's being processed, we can be inside
register_usb_transport still when we call unregister_usb_transport,
leading to bad things happening. Move the call of
register_usb_transport into the scope guarded by usb_handles_mutex.

Previously, we would attempt to delete a usb_handle in both
device_disconnected and usb_close. If the one in device_disconnected
happened to happen first, usb_close would abort when it failed to find
the handle it was supposed to own.
