[stgt] [PATCH v2] add --bsopts flag, pass to bs_init()

[Dan Mick]

[ Identical to the prior version, just rebased onto current master ]

This patch implements the generic mechanism of passing backing-store-
specific options to the backing store module's bs_init entry point.
Each backing-store module gets a new parameter, char *bsopts, 
added to its bs_init.

No semantics or even syntax are imposed on the option string, other
than that commas are not permitted, because tgtadm communicates to
tgtd using a block of key=val,key=val,key=val options, and there's
no provision for escaping commas.

tgtadm.8 is updated as well
