PCI parallel port devices can IRQ share so we should stop them hogging
the line and making a mess on modern PC systems. We know the sharing
side works as the PCMCIA driver has shared the parallel port IRQ for
some time.

Currently a parport_driver can't get a handle on the device node for the
underlying parport (PNPACPI, PCI, etc). That prevents correct placement of
sysfs child nodes, which can affect things like power management.
This patch adds a field to "struct parport" pointing to that device node, and
updates non-legacy port drivers to initialize that device pointer. That field
replaces the analagous PCI-only support in parport_pc.

"extern inline" doesn't make much sense.

Add missing "struct" keyword preventing compilation with DEBUG_PARPORT
defined. Also add some "const".

Spotted by a Fedora user. Compiling with DEBUG_PARPORT set fails due to
the broken cast.
Just remove it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
