ISCSI: Switch to using READ16/WRITE16 for I/O to the LUN

This allows using LUNs bigger than 2TB. Keep using READ10 for other
device types such as MMC.

ISCSI: redo how we set up the events

Call qemu_notify_event() after updating events. Otherwise, If we add
an event for -is-writeable but the socket is already writeable there
may be a delay before the event callback is actually triggered.

Those delays would in particular hurt performance during BIOS boot and...

ISCSI: Add support for thin-provisioning via discard/UNMAP and bigger LUNs

Update the configure test for libiscsi support to detect version 1.3
or later. Version 1.3 of libiscsi provides both READCAPACITY16 as well
as UNMAP commands.

Update the iscsi block layer to use READCAPACITY16 to detect the size of...

iSCSI block driver

This provides built-in support for iSCSI to QEMU.

This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices.
It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host....
