cc2b0c9b1d Set SO_KEEPALIVE before TCP_USER_TIMEOUT 
For TCP_USER_TIMEOUT to work it seems to be necessary that SO_KEEPALIVE is
enabled. RFC5482 section 4.2 also says that the TCP_USER_TIMEOUT has to be
less than the keepalive timeout. This means less than 30000 ms in the
current libiscsi default settings for TCP keepalives.

326b2ea49d Add backoff mechanism to iscsi_reconnect 
This patch adds a linear backoff mechanishm + jitter in case
a reconnect fails. If there is a longer outage this is to
avoid a large amount of simultaneous connects to the storage.

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.

91267f5aaa Limit immediate and unsolicited data to FirstBurstLength 
RFC3270 describes in section 12.14 that immediate and unsolicited data
sent from the initiator to the target must not exceed FristBurstLength
bytes in total.

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.

ce2db039a5 TEST: try to make 0410 nicer 
0410 is the first test for the MMC commandset.
This commandset is in hindsight a bit more complex than other commandsets
in that we have to handle quite a lot of cases :
1, if it is not a MMC device, we should check we get INVALID_OPCODE and then
bail.
Then if it is a MMC device, there are at least three different cases we have to
handle:
2.a  If there is no medium in the device
2.b there is media, but the medium is blank
2.c there is readable medium

this makes MMC tests a lot more complex than other commandsets
so we have to try to get this one as nice and simple as possible so we can
reuse this test as the framework when adding other MMC tests.

(even the 2.b test is not 100% right,   since if the medium is BR, then a blank disk will fail with sense,  but blank pre-BD mediums will not fail the READTOC command)
