3b05e9996f Move cancel_task and cancel_all_tasks from scsi-lowlevel.c to scsi-command.c 
These two functions belong in the iscsi layer, not the scsi layer so move them
out from scsi-lowlevel.c so that we can start turning scsi-lowlevel.c to a pure
scsi layer and remove all dependencies to iscsi from it.

50e7c682bb Add a logging subsystem and change all DPRINTF to ISCSI_LOG 
Add a mechanism where we can set a logging subsystem that libiscsi can use.
Create an example 'log to stderr' that utilities can use for convenience.

ad9cd56b2d Add setters for TCP keepalive values 
This patch adds 3 functions to set the 3 keepalive values TCP_KEEPIDLE, TCP_KEEPCNT
and TCP_KEEPINTVL. The values have to be set after iscsi context creation and are
then configured on the socket on each new connection.

f973608578 Add iscsi_tcp_set_user_timeout function 
This patch adds a user configurable option to set the TCP_USER_TIMEOUT
socket option. With this timeout set a broken TCP session is shutdown
after a given timeout even there are unacked packets. SO_KEEPALIVE
seems not to work in this case.

b673d8ed57 CONNECT: export the iscsi_reconnect() function. 
There are situations where you may want to trigger an iscsi reconnect
explicitely from an application so make this function exposed to applications.

d5f646099d READ10/WRITE10: Change these functions to sue the same signatures as the other READ/WRITE 
Harmonize the signatures for READ10/WRITE10 to match the ones for READ12/16 and WRITE12/16

This breaks the API/ABI so this forces the next version of the library to bump the major version to 2.0

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.
