Module Name:    src

Modified Files:
        src/sys/dev/pci: if_vge.c if_vgereg.h

Log Message:
Make vge(4) look a NetBSD native driver like pcn(4) or epic(4) etc:
- merge if_vgevar.h into if_vge.c since no other file refers it
- rename some macro (VGE_TX_DESC_CNT -> VGE_NTXDESC etc.) and structs
- change prefixes of structure members to represent parents
- put TX and RX descriptors into single struct vge_control_data and
  allocate DMA memory at once
- no need to specify BUS_DMA_ALLOCNOW
- define appropriate macro for offsets and addresses of DMA descriptors
- define struct vge_txsoft and vge_rxsoft, and put common data for
  each descriptor into them
- remove struct vge_list_data and move its members into struct vge_softc
- remove #ifdef DEVICE_POLLING code we don't support
- merge vge_[tr]x_list_init() functions into vge_init()
- use aprint_error() to print errors
- put splnet(9) where appropriate and remove unused VGE_{LOCK,UNLOCK}() macro
- clear TX timeout only if there is no pending descriptor
- check dm_nsegs properly otherwise padding short packets could fail
- prepare zero'ed DMA memory to pad short packets rather than putting
  random data
- fix a wrong VGE_TXDESCSYNC() usage which should be VGE_TXFRAGSYNC()

Tested on my i386 which is my development machine.
(more bus_dmamap_sync(9) cleanup will be done later)
