MFC r259182:

Fix handling for empty auth-groups. Without it, ctld child process
would either exit on assertion, or, if assertions are not enabled,
fail to authenticate the target.

Remove svn:mergeinfo from the releng/10.0 branch.

After branch creation from stable/10, the stable/10 branch mergeinfo
was moved to the root of the branch.

Since there have not been any merges from stable/10 to releng/10.0
yet, we do not need to track any of the existing mergeinfo here.

Merges to releng/10.0 should now be done to the root of the branch.

For future branches during the release cycle, unless otherwise noted,
this change will be done as part of the stable/ and releng/ branch
creation.

- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Fix off-by-one.

Fix several problems in the new iSCSI stack; this includes interoperability
fix for LIO (Linux target), removing possibility for the target to avoid mutual
CHAP by choosing to skip authentication altogether, and fixing truncated error
messages in iscsictl(8) output. This also fixes several of the problems found
with Coverity.

Note that this change requires world rebuild.
