NEW FEATURES:
- Minor numbers can now be manually assigned with the unit_video parameter. This
  is a V4L2 feature, but does not require V4L2. Requires kernel 2.4.5 or later.
- Autodetection of MMX support (no mmx code is used yet, though).
- Added detection for Suma eON camera (custom_id 46).
- Driver reports assigned minor number(s) in kernel log

BUG FIXES:
- Uncompressed data zero-padding removal was causing problems, so it is now
  disabled unless you enable it with the remove_zeros parameter.
- Made the decoder_* functions static.
- Packet SOF header should be passed to the OV518 decompressor.
- Replaced SMP-unsafe sleep_on() with wait_event(), in VIDIOCSYNC and read().
- ov511.h: NTSTATUS codes should be static

INTERNAL CHANGES:
- Module parameters are no longer initialized to 0. This moves them to the BSS
  segment (saves a few bytes of code).
- Optimizations to VIDIOCSYNC
- Removed ov511_vmalloc() and ov511_vfree() (no longer needed by ov511_decomp)
- Removed old OV7620 initial reg settings
- ov511.h: Removed unneded wait_interruptible macro
- ov511.h: Removed useless and usb_device forward declatation.
- ov511.txt: Updated module params and status, added link to install page
- ov511_decomp.c: Optimizations and code cleanups
- ov511_decomp.c: Removed unnecessary (and highly wasteful) temp buffer
