[PATCH 0/6] Misc code updates

[Zdenek Kabelac <zkabelac@redhat.com>]

Small patchset contains various bits of code I keep in front of my tree.

First strict-aliasing is a bit contraversional and needs bigger review.

Configure patch basicaly cleanups help strings with the use of
AC_HELP_STRING.

Nextbit patch is tiny code optimization.

Backtrace patch skips printing of backtrace in the log if the situation
is not an error case.

Memlock slightly modifies memory map printing.

Last patch for dmsetup returns '0' exist status when showing option help.
