The acpi server needs to survive after the shutdown notification,
so it can serve S_acpi_sleep() RPC to actually shut down the machine.
Therefore we need to keep the server alive and not respond to the
trivfs goaway request.

This fixes a known race condition in bootstrapping by
separating the fsys_startup call from the server demuxer loop
into two separate functions that the caller can decide
when to call.

This will allow callers to manage their own server routine.

We do not actually want to shut everything down. For instance, we still have
to be able to start the acpi translator to perform the actual shutdown.
What we however have to do is syncing the disks.

bootstrap translators may not wish to appear in the FS, and the name of
the translator does not have to match the path where it is getting
installed.
* libmachdev/machdev.h (machdev_trivfs_init): Add path parameter.
* libmachdev/trivfs_server.c (machdev_trivfs_init): Add path parameter,
set devnode only if it is not NULL.
(trivfs_S_fsys_init): Only call install_as_translator when devnode is not NULL.
* /rumpdisk/main.c (main): Add path parameter.

machdev users can now pass along a port to the next translator in the
bootstrap chain (bootstrap_resume_task), that they'll get from their
command line set by the bootloader. machdev will then call task_resume
on it as appropriate. It will also have the opportunity to get
fsys_getpriv calls, and thus redirect the device master port, thus
having the opportunity to expose its devices on the device master port,
as if they were handled by the kernel.
