Introducing iSCSI userspace library.

 * This is the initial patch of the library libopenscsiusr.so, so we have no
   actual code on iscsi functionality, just introduce a code layout.
 * The library is created by following the guideline of libabc.
 * Documentation is done by using linux kernel-doc script generating
   manpages out of header files.
