Revert "Update irqs on reset and device load"

This reverts commit 3dcd219f09d6c1817bf9a132899e6b925f7a0914.

It is incorrect to call qemu_irq functions (or any other functions that
access other device state) during savevm/loadvm.

Rename pci_register_io_region() to pci_register_bar()

Remove io_index argument from cpu_register_io_memory()

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

net: add fd_readv() handler to qemu_new_vlan_client() args

net: re-name vc->fd_read() to vc->receive()

VLANClientState's fd_read() handler doesn't read from file
descriptors, it adds a buffer to the client's receive queue.

Re-name the handlers to make things a little less confusing.

e1000: Ignore reset command

When a reset is requested, the current e1000 emulation never clears the
reset bit which may cause a driver to hang. This patch masks the reset
bit out when setting the control registert, so the reset is immediately
completed.

KVM: Coalesced MMIO support

MMIO exits are more expensive in KVM or Xen than in QEMU because they

Good examples of this include VGA pixel operations when in a planar...
