1aa8e4e5b2 lib/iscsi: Add iscsi_portal_group_set_auth for per portal group CHAP authentication
Add an new RPC iscsi_portal_group_set_auth. This RPC overwrites
the setting of CHAP authentication for discovery sessions by the
global parameters specific for the portal group.

b72893a6f2 lib/iscsi: Portal group holds CHAP params and passes them to connections
This is another preparation to support per portal group CHAP authentication
for discovery session.

Add CHAP params into struct spdk_iscsi_portal_grp, and initialize them
by global parameters at spdk_iscsi_portal_grp_create().

Copy CHAP params from portal group to connection at spdk_iscsi_conn_construct().

fb641c4b54 iscsi: Assign connections to poll groups instead of lcores.
This patch binds poll groups to SPDK thread through IO channel and
assigns connections to poll groups instead of cores.

iSCSI subsystem registers iSCSI global object as an IO device, and create
poll groups as context of IO channels of the IO device.

Each portal get and hold portal group on which the corresponding acceptor is
running.

When a connection is constructed, iSCSI subsystem assigns a poll group
to the connection by getting it from the corresponding portal.

When a connection enters full-feature phase, iSCSI subsystem schedules
the connection to a poll group by round-robin.

Then, each connection can know its running SPDK thread directly and can
use SPDK message passing infrastructure instead of SPDK event framework.

By this change, iSCSI connections are binded to SPDK thread, and not
binded to processor core anymore.

Some other changes in this patch are
- core ID is removed from the output of get_iscsi_connections RPC. The
  upcoming patches will change the RPC to use spdk_for_each_channel and can
  access SPDK thread safely, and add SPDK thread ID instead.
- utilize UT multithread framework added by the last patch to test
  iSCSI poll groups by UT.

3af8e26df8 iscsi: Change function names of iSCSI subsystem configuration
Portal, portal group, initiator group, and target node don't use fixed size
array anymore. To use the same naming rule in iSCSI subsystem and in SPDK
is helpful to understand and maintain. Current naming rule is not bad but
to use unified and compact name is prioritized at this time.

This patch changes function names as follows:
- spdk_iscsi_init_tgt_nodes() -> spdk_iscsi_parse_tgt_nodes()
- spdk_cf_add_iscsi_tgt_node() -> spdk_iscsi_parse_tgt_node()

- spdk_iscsi_portal_grp_array_create() -> spdk_iscsi_parse_portal_grps()
- spdk_iscsi_portal_grp_create_from_configfile() -> spdk_iscsi_parse_portal_grp()
- spdk_iscsi_portal_create_from_configline() -> spdk_iscsi_parse_portal()
- spdk_iscsi_portal_grp_array_destroy() -> spdk_iscsi_portal_grps_destroy()

- spdk_iscsi_init_grp_array_create() -> spdk_iscsi_parse_init_grps()
- spdk_iscsi_init_grp_create_from_configfile() -> spdk_iscsi_parse_init_grp()
- spdk_iscsi_init_grp_array_destroy() -> spdk_iscsi_init_grps_destroy()

For example "parse" is already used to explain the operation in portal_grp.c.
Hence using "parse" is familiar and not strange in iSCSI.

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.

2ea005f0a9 iscsi: Unify the ordering of PG create_op between conf-file and JSON-RPC
Orderings of portal group create operation are diferrent between
config file and JSON-RPC. Unification is necessary for correct
concurrency control and the global accept poller like NVMf-tgt.
Hence unify the ordering of operations in this patch.

Common ordering of portal group create operation between configuration
file  and JSON-RPC after this patch is the following:
 - create a portal group
 - create portals
 - add the portals to the portal group
 - open the portals of the portal group
 - add the portal group to the global portal group list

After this patch, the gap between listening socket and accepting socket
will be increased a little when portals groups are creted by config file.
However this will cause no issue because of the TCP backlog and resend
mechanism.

Besides, necessary concurrency control is added and minor refactoring
is done.

About portal group delete operation, orderings of application shutdown
and JSON-RPC are already unified.

601bcbcf66 util: extend cpumask to hold more than 64 cpus
Fixes github issue #218.

This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.

spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.

This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

This patch does the following:

 - parsing configline of portal is difficult to understand and
   hence it is refactored.
 - UT code is added.
