Shuhei Matsumoto 893e02a54f iscsi: Remove the prefix spdk_ from names of private functions 
iSCSI library had used the prefix spdk_ for most functions regardless
of private or public. Using the prefix spdk_ only for public functions
will be helpful to distinguish private and public functions, and
will be helpful to investigate issues or do further improvement.

Besides in iscsi.c static variable spdk_arc4random_initialized had
the prefix spdk_, and change it to g_arc4random_initialized according
to the SPDK's good practice.

iSCSI library still have some issues but is more stable than before
and now will be the good time to adjust the naming rule to other
libraries.

This patch doesn't change any behavior.
