Revised IPv6 workaround code #379

Previous patch #379 was incorrect.
IPv6 workaround code use push function, but push is
appending value whenever execute check_http.(That's a waste...)
So rewrite workaround code use substitution.
High: clvm: automatically set lvm.conf's locking_type=3

lvm comes with a cli tool we can use to set/unset the
locking type. When clvmd is in use, it is safe to assume
that locking_type=3  (clustered locking) should be in use.
Otherwise there would be no reason to run the clvmd to begin
with.
Revised fix for Socket and Socket6 module functions conflict.

Previous fix #365 was incomplete.
RHEL6 not have pack_sockaddr_in6/sockaddr_in6/unpack_sockaddr_in6 in
Perl Socket module.
But those "_in6" symbols used by check_connect or check_sip.
So import those "_in6" symbols only if not implement in Socket module.
Also modify lack inet_ntop module.
High: Xen: Replace use of xm with xl (bnc#882548)

The xm command line tool has been deprecated in favor of the xl
toolstack.
For more information, see:
  - http://wiki.xen.org/wiki/MigrationGuideToXen4.1
  - http://wiki.xen.org/wiki/XL#Upgrading_from_xend

Use xl if available, else fall back on using xm.

heredoc delimiter as some editors don't handle it properly.
