* remotes/bonzini/tags/for-upstream:
  ossaudio: fix memory leak
  ui: convert VNC to use generic cipher API
  block: convert qcow/qcow2 to use generic cipher API
  ui: convert VNC websockets to use crypto APIs
  block: convert quorum blockdrv to use crypto APIs
  crypto: add a nettle cipher implementation
  crypto: add a gcrypt cipher implementation
  crypto: introduce generic cipher API & built-in implementation
  crypto: move built-in D3DES implementation into crypto/
  crypto: move built-in AES implementation into crypto/
  crypto: introduce new module for computing hash digests
  vl: move rom_load_all after machine init done
