The interrupt handler disables all interrupt sources when a valid
interrupt occurs. Just disable the triggered interrupt source so we can
still get interrupts for the other interrupt source.
Also add a comment indicating why the triggered interrupt source is
disabled. The interrupt sources are level-sensitive and indicate
hardware errors that are likely to be persistent, so if we reenabled
them they would just keep triggering repeatedly.

The `insn_bits` handler for the special digital input subdevice used for
interrupts currently uses `s->state` for the data value, which is set to
the value of the APCI2032_INT_STATUS_REG register when a valid interrupt
occurs. Just read the live register contents in the `insn_bits` handler
instead of relying on the interrupt service routine to read it for us.
The register contains a couple of hardware error status bits. They
might also be valid even when the corresponding bits have not been
enabled in the APCI_INT_CTRL_REG register in which case this would be
useful for checking for hardware errors without using interrupts, but
this needs to be checked.

If the call to `comedi_buf_put()` fails in the interrupt routine, set

flag will have also been set by `comedi_buf_put()` in this case.

The subdevice type and flags are initialized incorrectly for the
interrupt subdevice - the SDF_CMD_READ value belongs in the subdevice
flags. Fix it. Also set the number of channels to 2 since there are 2
interrupt sources each with its own status bit.

Put the hardware into a safe state before enabling the interrupt. In
the interrupt routine, check the device has been fully configured by
checking `dev->attached`. In particular, `dev->read_subdev` could be
NULL early on and although the hardware's status register should
indicate no interrupt has occurred (since it's been put into a safe
state), it's better not to rely on it.

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.

This patch changes the omapdrm KMS to bypass the omapdss "compat"
layer and use the core omapdss API directly. This solves some layering
issues that would cause unpin confusion vs GO bit status, because we
would not know whether a particular pageflip or overlay update has hit
the screen or not. Now instead we explicitly manage the GO bits in
dispc and handle the vblank/framedone interrupts ourself so that we
always know which buffers are being scanned out at any given time, and
so on.
As an added bonus, we no longer leave the last overlay buffer pinned
when the display is disabled, and have been able to add the previously
missing vblank event handling.
