implemented in one place, rather than for every PCI device.

Clearly, this doesn't help for non PCI devices, which could also be
IOMMU translated on some platforms.  It is also problematic for the
devices which have both PCI and non-PCI version (e.g. OHCI, AHCI) - we
cannot use the the pci_dma_*() functions, because they assume the
presence of a PCIDevice, but we don't want to have to check between
pci_dma_*() and cpu_physical_memory_*() every time we do a DMA in the
device code.

This patch makes the first step on addressing both these problems, by
introducing new (stub) dma helper functions which can be used for any
DMA capable device.

These dma functions take a DMAContext *, a new (currently empty)
variable describing the DMA address space in which the operation is to
take place.  NULL indicates untranslated DMA directly into guest
physical address space.  The intention is that in future non-NULL
values will given information about any necessary IOMMU translation.

DMA using devices must obtain a DMAContext (or, potentially, contexts)
from their bus or platform.  For now this patch just converts the PCI
wrappers to be implemented in terms of the universal wrappers,
converting other drivers can take place over time.

Better support for dma_addr_t variables

A while back, we introduced the dma_addr_t type, which is supposed to
be used for bus visible memory addresses.  At present, this is an
alias for target_phys_addr_t, but this will change when we eventually
add support for guest visible IOMMUs.

There are some instances of target_phys_addr_t in the code now which
should really be dma_addr_t, but can't be trivially converted due to
missing features which this patch corrects.

 * We add DMA_ADDR_BITS analagous to TARGET_PHYS_ADDR_BITS.  This is
   important where we need to make a compile-time (#if) based on the
   size of dma_addr_t.

rtl8139: validate rx ring before receiving packets

Commit ff71f2e8cacefae99179993204172bc65e4303df prevent the possible
crash during initialization of linux driver by checking the operating
mode.This seems too strict as:

- the real card could still work in mode other than normal
- some buggy driver who does not set correct opmode after eeprom
 access

So, considering rx ring address were reset to zero (which could be
safely trated as an address not intened to DMA to), in order to
both letting old guest work and preventing the unexpected DMA to
guest, we can forbid packet receiving when rx ring address is zero.
