hw/pci-bridge: set PCI_INTERRUPT_PIN register before shpc init

The PCI_INTERRUPT_PIN will be used by shpc init, so
was moved before the call to shpc_init.

hw/vmxnet3: set interrupts using pci irq wrappers

pci_set_irq uses PCI_INTERRUPT_PIN config register
to compute device INTx pin to assert/deassert.

An assert is used to ensure that intx received
from the quest OS corresponds to PCI_INTERRUPT_PIN.

hw/vfio: set interrupts using pci irq wrappers

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.

save INTX pin into the config register before calling

hw: set interrupts using pci irq wrappers

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....

hw/pcie: AER and hot-plug events must use device's interrupt

The fields hpev_intx and aer_intx were removed because
both AER and hot-plug events must use device's interrupt.
Assert/deassert interrupts using pci irq wrappers instead.

hw/pci: removed irq field from PCIDevice

Instead of exposing the the irq field,
pci wrappers to qemu_set_irq or qemu_irq_*
can be used.

memory: Change MemoryRegion priorities from unsigned to signed

When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only...

hw/pci: partially handle pci master abort

A MemoryRegion with negative priority was created and
it spans over all the pci address space.
It "intercepts" the accesses to unassigned pci
address space and will follow the pci spec:
1. returns -1 on read
2. does nothing on write...

hw/core: Add interface to allocate and free a single IRQ

qemu_allocate_irq returns a single qemu_irq.
The interface allows to specify an interrupt number.

qemu_free_irq frees it.

hw/pci: add pci wrappers for allocating and asserting irqs

Interrupt pin is selected and saved into PCI_INTERRUPT_PIN
register during device initialization. Devices should not call
directly qemu_set_irq and specify the INTx pin on each call.

Added pci_* wrappers to replace qemu_set_irq, qemu_irq_raise,...
