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.

c3bc40a6ef io_channel: add return value to pollers
This will be used to track time used in pollers - each poller can now
indicate if it found any work to do or not.

For cases where it was obvious and the infrastructure was already in
place, existing pollers have been modified to return 0 or a positive
value to indicate whether work was done.  Other pollers have been
modified to return -1 by default, indicating that the poller isn't
indicating anything about whether work was performed.  This will allow
us to find un-annotated pollers easily in the future and fix them
incrementally.

4b10029435 net, iscsi: add struct spdk_sock abstraction
This provides an abstraction layer around TCP
sockets.  Previously we just used fd integers, but
we don't want to be tied to integers for alternative
userspace TCP stacks.

Future patches will do more work to enable multiple
implementations of this abstraction.  For now, just
get the abstraction in place for POSIX sockets and
make all of the iSCSI changes associated with it.

67c9ea6ad9 net: add sock.h
The socket-related code was already broken out into
lib/net/sock.c, so break out the header portions
from include/spdk/net.h into its own sock.h.

This prepares for some upcoming changes in how
TCP sockets are abstracted, to enable alternative
userspace TCP stack implementations to be used with
SPDK.

d777bfd148 iscsi: Remove nested, duplicated, or unreferenced file inclusion
When header files include other header files, it can be difficult
to read the chain of relationships. Hence remove obvious nested
header inclusion.

Remove obvious unreferenced header inclusion too.

This leaves more flexibility for future changes to the poller

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.
