* Resynchronise with Debian (LP: #427854). Remaining changes: Ubuntu-specific adjustments (probably): - Use i686 for lpia in cputable and triplettable. - Hack Dpkg::Arch to return i686 for lpia. - Move various Conflicts to Breaks, since upgrades from stable Ubuntu releases support Breaks.
Miscellaneous bug fixes: - Avoid duplicate attempts to [f]close in obscure error situations which might conceiveably close wrong fds. - Revert change to stop outputting a newline after a postinst is run (Debian #392317). - Use the two-arg form of open in Dpkg::Control so that "-" can be passed to parse stdin as a control file (Debian #465340).
Launchpad integration: - Add Launchpad-Bugs-Fixed handling in a few more places.
Build options: - Point to https://wiki.ubuntu.com/DistCompilerFlags from dpkg-buildpackage(1). - Set default LDFLAGS to -Wl,-Bsymbolic-functions. (We've already taken this hit in Ubuntu.) - Implement handling of hardening-wrapper options via DEB_BUILD_OPTIONS.
