50594830bd Task Management. When we abort a task or a task set, or reset the lun or target 
we must also cancel all active tasks.
This will trigger all affected tasks to have their callback invoked with
SCSI_STATUS_CANCELLED

7a4b1d2640 Fix documentation of how to use 'zero-copy' reads. 
The function to specify the read buffers is called
scsi_task_add_data_in_buffer, not scsi_task_add_data_buffer

3a39201543 Add 'zero-copy' in libiscsi for reads. 
It is not real zero-copy since the data is still copied in the kernel,
but it avoids copying the data inside libiscsi as well as in the callback.

For SCSI tasks that will return data from the target, the application can now
specify application buffers for libiscsi to read the data directly into.
This is done by calling scsi_task_add_data_in_buffer(task, ...

These buffers need not be linear, you can specify different areas to read into
by calling this function several times.

See examples/iscsiclient.c for an example.

343d86dca7 get rid of the _async() scsi functions. 
We dotn need two interfaces that only diuffer in whether they return a pointer or NULL vs an semiidentical interface that returns 0 or <0

All uses of _async() for scsi tasks should be replaced with the equivalent _task() function instead

f4f6ef5033 change dont automatically free the scsi_task once the callback completes. 
Freeing the scsi_task structure is the responsibility of the application
to either do so during the callback, or later.

76208e1eff Rename the _send() functions to _task() 
These functions are also async functions for SCSI commands but they return
a task structure or NULL.

This task structure can be used in task management functions to abort the task or a whole task set.

c29b9a2aae Add a new "iscsi_queue_length()" which will tell us how many commands 
are in flight at the moment.
Aside from commands, we also consider the "has not yet connected completely" as being an i/o.

When this command returns 0 it means we are connected ant the iscsi connection is idle, with no commands in flight.

KVM needs a function to detect idleness like this for its block layer io_flush
function.

ec08fe7a45 Read10/Write10 parameters 
LBA is uint32_t for read/write10

Also store the lba/numblocks arguments in the task structure for read10/write10
This makes it much easier to implement a fully async "read lots/write lots"
applications.
