Change the behavior of construct_raid_bdev RPC to be consistent with
other bdev modules.
Create a config of raid bdev first. Then create a raid bdev based
on the config.
If both succeed, the config and the raid bdev are not removed even if
any failure occur later in construct_raid_bdev RPC. Otherwise, both
are removed and return failure.
During iteration of adding base bdevs in construct_raid_bdev RPC,
- skip any nonexistent bdev and move to the next base bdev.
- if adding any base bdev fails, move to the next bdev.
- if adding base bdevs don't fail but any base bdev doesn't exist,
the raid bdev is in the configuring state and return success.
- if adding base bdev fails, the raid bdev is in the configuring state
and return failure.
- if all adding base bdevs succeed, configure the raid bdev. If configuring
the raid bdev fails, move the raid bdev to the offline state and return
failure. If configuring the raid bdev succeed, return success.
check_and_remove_raid_bdev() becomes unused in raid_bdev_rpc.c but
is still necessary in UT. Hence move this function to UT.
In UT, finding a raid bdev config by name becomes necessary. Hence
factor out the iteration to a function and use the function in UT.

When construct_raid_bdev RPC is callled, even if all adding base bdevs
to it fail, a raid bdev with no base bdev should exist and be in

Extract raid_bdev_create() from raid_bdev_add_base_bdev() and put it

This patch removes the test code.

For secure iSCSI targets, dynamic reconfiguration of CHAP secrets is
must to have.
Currently CHAP secrets are loaded for every CHAP authentication
operation. The current implementation will not work correctly
when CHAP secrets in the file are changed dynamically.
If SPDK loads CHAP secrets from the file only at boot and they can be
configured by RPCs, user can change CHAP secrets safely during run time.
Even if there are any users who expect dynamic reconfiguration of
CHAP secrets based on the current implementation, if we provide
this better alternative based on RPCs, they will be able to continue to
satisfy their requirement.
This patch change the current implementation so that SPDK loads
CHAP secrets from the file once at boot and uses them in memory
hereafter.
Besides, use fixed size buffers to hold CHAP secrets.
Previously dynamically allocated buffers by strdup() had been used,
but it required many nomem checks and should be avoided.
Other iSCSI targets/initiators have used fixed size buffers and SPDK
follows others.
Set the size of buffers for both user names and secrets to 256 (the
last byte is for NULL termination). 256 is sufficiently large
compared with others.
CHANGELOG will be updated in the separate patch because new RPCs will
be added instead.

raid_base_bdev_info is sufficiently descriptive as name and so
names of member variables in raid_base_bdev_info can be simplified.

A number of modules (RAID, logical volumes) have logical
"stripes" that require splitting an I/O into several
child I/O. For example, on a RAID-0 with 128KB strip size,
an I/O that spans a 128KB boundary will require sending
one I/O for the portion that comes before the boundary to
one member disk, and another I/O for the portion that comes
after the boundary to another member disk. Logical volumes
are similar - data is allocated in clusters, so an I/O that
spans a cluster boundary may need to be split since the
clusters may not be contiguous on disk.
Putting the splitting logic in the common bdev layer ensures
bdev module authors don't have to always do this themselves.
This is especially helpful for cases like splitting an I/O
described by many iovs - we can simplify this a lot by
handling it in the common bdev layer.
Note that currently we will only submit one child I/O
at a time. This could be improved later to submit multiple
child I/O in parallel, but the complexity in the iov splitting
code also increases a lot.
Note: Some Intel NVMe SSDs have a similar characteristic.
We will not use this bdev stripe feature for NVMe though -
we want to primarily use the splitting functionality inside
of the NVMe driver itself to ensure it remains fully
functional. Many SPDK users use the NVMe driver without
the bdev layer.

This patch series will refactor/improve CHAP authentication and consolidate
it into iscsi_subsystem.c.
To get better reviews, this patch just moves spdk_iscsi_chap_get_authinfo()
from iscsi.c to iscsi_subsystem.c.

A new unit test in an upcoming patch will initialize the bdev
layer separately, so modify the existing tests now so that
they properly cleanup the bdev layer after the unit test
that initialized it is complete.
