Tags: 0.15.0+noroms-0ubuntu1
https://launchpad.net/bugs/878162
* New upstream release
* Remaining changes from upstream:
  - removed all binary roms and tests/pi_10.com
* Removed Detect-and-use-GCC-atomic-builtins-for-locking.patch - non-NPTL
  implementations were removed with commit
  02615337ef295443daa03233e492194e289a807e
* Drop spice-qxl-locking-fix-for-qemu-kvm.patch - should be unnecessary
  as of commit 196a778428989217b82de042725dc8eb29c8f8d8
* drop patches applied upstream:
  - CVE-2011-1751.diff
  - virtio-guard-against-negative-vq-notifies-CVE-2011-2512.diff
  - CVE-2011-2527.patch
  - fix-pa-configure.patch
* Refreshed the remaining patches:
  - larger_default_ram_size.patch
  - CVE-2011-2212-virtqueue-indirect-overflow.patch
  - qemuifup-fix-paths.patch
  - vpc.patch
* e1000-Dont-set-the-Capabilities-List-bit.patch - switched to the
  cherrypicked upstream patch (as the source file changed quite a bit,
  and the hand-ported patch backported to 0.14.1 does not apply).
* Drop qemu-kvm-spice (all changes from 0.14.1+noroms-0ubuntu7), it will
  need its own source package (LP: #878162)
