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

0be42c8833 If an application specifies zero-copy read-buffers to read the data into 
for a read10 call, the application might have specified too few buffers
for the full I/O.
For example if the application tries to read just 512 bytes off a MMC device.

In this case we wopuld run out of buffers and fail with a SEGV.

Instead of failing like this, return NULL from the function to locate a suitable buffer and read the remaining data from the command into the callback buffer instead, just like when no read-buffer at all has been specified.

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.

024f7dc94e In iscsi_scsi_response_cb() 
dont pick task up from the argument, since this callback can be invoked
from places where we dont have/know the task strucutre and it is thus NULL.

Instead pick it up from scsi_cbstruct.

This prevents a SEGV when processing REJECT to SCSI commands.
(the scsi command callback dereferences the task pointer)

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.
