* Version 1.12 introduces support for libdw (provided by elfutils).
libdw adds source lines & numbers to backtraces. A new "dw"
packageconfig added for enabling/disabling this feature.
In addition, the old patch for deterministic unwind configuration
was replaced with one that also allows the same for the dw
configuration. This new patch was also submitted to bugzilla.
* Leftover docbook cruft was removed, meaning that the
"--disable-docbook" configure switch is gone.
