USBIP daemon relies on functions available in glib2 library
to spawn handler code for incoming connection. This makes the
whole program dependent on glib2 library, which is a GNOME library
that on systems that don't have GNOME results in pulling more
dependency, only to be able to run a relatively trivial
socket-based program.
While this may not seem to be a problem on full-blown desktops
that already have the necessary libraries, it is a big issue
on small embedded systems (think USB hub with an Ethernet port)
that only have bare essentials in their file systems.
This patch eliminates glib2 dependency by reworking the
code to use lower level system calls to dispatch connection
handler. Instead of using glib2-style event loop and dispatching
mechanism, just do a ppoll(2) system call in our own loop and call
accept(2) followed by fork(2) on the socket that has incoming
connection. Stevens' books taught us that more than twenty
years ago. No need for anything smarter in a simple server, such
as usbipd.

The usb_device structure contains an array of usb_device "children".
This array is only valid if the usb_device is a hub, so it makes no
sense to store it there. Instead, store the usb_device child
in its parent usb_port structure.
Since usb_port is an internal USB core structure, add a new function to
get the USB device child, usb_hub_find_child(). Add a new macro,
usb_hub_get_each_child(), to iterate over all the children attached to a
particular USB hub.
Remove the printing the USB children array pointer from the usb-ip
driver, since it's really not necessary.

USB autosuspend suspends vhci_hcd. In this process hcd_bus_suspend gets
executed which puts vhci_hcd in suspend state and calls vhci_hub_status.
vhci_hub_status function checks hub state and if it is in suspend state,
usb_hcd_resume_root_hub gets executed which resumes hub and if hub is
idle, again autosuspend puts it in suspend state and this goes on.
vhci_hub_status should resume hub only when hub port is in suspend state
and hub port status has changed.

Almost all of usbip assumes that the_controller->lock is acquired
before vdev->priv_lock. The exception is in
vhci_device_unlink_cleanup(), where locks are acquired in the
reverse order. This leads to occasional deadlocks.
Fixing this is a bit fiddly, as the_controller->lock can't be held
when calling usb_hcd_unlink_urb_from_ep() in the middle of the list
traversal. As I can't rule out concurrent callers to this function
(perhaps it is safe?), the code here becomes slightly uglier - when
locks are dropped in the middle so the list may have emptied itself
(not even list_for_each_entry_safe is safe here).

stub_shutdown_connection() and vhci_shutdown_connection() use
task_is_dead() before kthread_stop(). This buys nothing and wrong.
kthread_stop() is fine even if this thread is dead. However, if it
is dead nothing protects this task_struct, we shouldn't touch this
memory.
Change the code to do the necessary get_task_struct/put_task_struct.
This patch assumes that
- xxx_shutdown_connection() is always called, so we can't
leak the task_struct.
- kthread_stop_put() can't be called twice on the same task.

When unbinding a device on the host which was still attached on the
client, I got a NULL pointer dereference on the client. This turned out
to be due to kthread_stop() being called on an already dead kthread.
Here is how I was able to reproduce the problem:
server:# usbip bind -b 1-2
client:# usbip attach -h server -b 1-2
server:# usbip unbind -b 1-2
This patch fixes the problem by checking the kthread before attempting
to kill it, as it is done on the opposite side in
stub_shutdown_connection().

Officially change stub_driver to usbip_host_driver. And, reorganize
usbip_host_driver.c while also cleaning up coding style.

Delay the printing of the output header until the list is received
from the remote host. This allows notification that the host does not
have any exportable devices.

Modify unbind to use libsysfs, and include a check to verify that the
device is actually using usbip-host before proceeding. The output
messages have been changed to be consistent with `usbip bind'.

Rewrite functions in terms of libsysfs, which eliminates a lot of
helper functions simplifying the file layout. Now, the two processes
taking place here, an unbind of the old driver and a bind of
usbip-host, are single functions and have been renamed along with the
controlling function. A check to see if the device is already bound to
usbip-host is now included.

Removes all of the helper functions that used a lot of hard-coded
values intead of libsysfs. Most of these functions were unused
anyway.

The library should not be displaying random messages intermixed with
those from the programs that use them. So, instead, change all of the
output from the library to debug only, and allow the programs to
decide what to tell the user. This also changes the messages to use
the same form, which makes understanding them easier.
