Hollywood Plus/DXR3 Linux Drivers

This release supports Linux 2.6, uses dynamic assignment of major numbers (for people who use devfs or udev), and has many minor bugfixes.

Semaphores are now used instead of spinlocks.
Fixes were made for the sparc64, powerpc, and
alpha platforms. 32-bit ioctls are now supported
in 64-bit systems. i2c support was fixed. Audio on
big-endian systems was fixed. The module options
for multiple cards were fixed. A O_NONBLOCK bug
was fixed.

This release contains a new em8300setup utility to replace em8300init, fixes multicard support, and provides some bugfixes.

Lots of bugs fixed related to audio playback were
fixed. Digital AC3 was fixed. poll/select support
was added, since it yields better responsiveness
in apps that use them. Mono audio playback on
digital output was fixed. Bugs related to
compilation on 2.2 and 2.5 kernels were fixed. A
new naming scheme is now used, where devices are
called /dev/em8300*-0, up to -3 if you have more
than 1 device. The driver now includes microcode
which works on both the Hollywood+ and the DXR3.
