c2836e2a9a DPRINTF add iscsi target_name if available

78a31ad4a1 Add iscsi_set_tcp_syncnt function 
This patch adds support for setting TCP_SYNCNT to overwrite
the system default values. This allows indirect support
for a configurable connect timeout.

Linux uses a exponential backoff for SYN retries starting
with 1 second.

This means for a value n for TCP_SYNCNT, the connect will
effectively timeout after 2^(n+1)-1 seconds.

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.

77d8e41be7 TESTS: Add a mechanism to temporarily disable the session reconnect 
Some tests may cause a target to drop the session.
For these tests we DO want the test tool to detect that the command
failed and later reconnect the session again when we proceed to the next subtest

1f98c40edf DATASN: We have to increment DATASN in each DATA-OUT PDU in a sequence. 
For writes that span across multiple DATA-OUT segments we have to
increment the DATASN field for each segment.
We didnt use to, and most targets were perfectly happy, ignoring that the DATASN was constant 0 for every DATAOUT we sent.
LIO however does check this and did cause it to reject the libiscsi test tool.
(This is something we should write a iscsi test for  so we can flag all non-LIO targets as broken and needing to be fixed)

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
