[Qemu-devel] Patch to add iSCSI configuration options

[Ronnie Sahlberg]

List,
Please find a patch that adds configuration options for iSCSI.
The patch allows setting the options either via -iscsi on the command
line or via a configuration file read by -readconfig

Options available at this stage are
* initiator-name to use when logging in to the targer
* header-digest setting to negotiate
* chap username
* chap password

Documentation for both manpage and qemu-doc are also updated

regards
ronnie sahlberg
