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 the `COMEDI_CB_OVERFLOW` event flag. Note that the `COMEDI_CB_ERROR` flag will have also been set by `comedi_buf_put()` in this case. Signed-off-by:

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. Signed-off-by:

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.

This comes handy when hacking with different cross compilers, some of which may or may not have _FORTIFY_SOURCE turned on by default. This patch allows us to turn _FORTIFY_SOURCE on by specifying --with-fortify option at configuration time (or to turn it off by specifying --without-fortify). If nothing is specified, default compiler behavior is assumed. Signed-off-by:

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. Signed-off-by:
