g_new(T, n) is safer than g_malloc(sizeof(*v) * n) for two reasons.
One, it catches multiplication overflowing size_t. Two, it returns
T * rather than void *, which lets the compiler catch more type
errors.
Perhaps a conversion to g_malloc_n() would be neater in places, but
that's merely four years old, and we can't use such newfangled stuff.
This commit only touches allocations with size arguments of the form
sizeof(T), plus two that use 4 instead of sizeof(uint32_t). We can
make the others safe by converting to g_malloc_n() when it becomes
available to us in a couple of years.

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.
An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.
Removed irq related fields from state if not used anymore.

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci
storage device.
NVMe is an open, industry driven storage specification defining
an optimized register and command set designed to deliver the full
capabilities of non-volatile memory on PCIe SSDs. Further information
may be found on the organizations website at:
http://www.nvmexpress.org/
This commit implements the minimum from the specification to work with
existing drivers.
