  net/slirp: simplify checking for cmd: prefix
  net/slirp: free forwarding rules on cleanup
  net/slirp: fix leaks on forwarding rule registration error
  slirp: add callbacks for timer
  slirp: replace trace functions with DEBUG calls
  slirp: replace QEMU_PACKED with SLIRP_PACKED
  slirp: replace most qemu socket utilities with slirp own version
  slirp: replace qemu_set_nonblock()
  slirp: add unregister_poll_fd() callback
  slirp: replace qemu_notify_event() with a callback
  slirp: move QEMU state saving to a separate unit
  slirp: do not include qemu headers in libslirp.h public API header
  slirp: improve windows headers inclusion
  slirp: add slirp own version of pstrcpy
  slirp: remove qemu timer.h dependency
  slirp: remove now useless QEMU headers inclusions
  slirp: replace net/eth.h inclusion with own defines
  slirp: replace qemu qtailq with slirp own copy
  slirp: replace remaining qemu headers dependency
  slirp: prefer c99 types over BSD kind
  slirp: improve send_packet() callback
  slirp: replace global polling with per-instance & notifier
  slirp: remove slirp_instances list
  slirp: use polling callbacks, drop glib requirement
  slirp: pass opaque to all callbacks
  slirp: API is extern C

Peter Maydell (2):
  slirp: Avoid marking naturally packed structs as QEMU_PACKED
  slirp: Don't mark struct ipq or struct ipasfrag as packed

Samuel Thibault (3):
  slirp: Avoid unaligned 16bit memory access
  slirp: replace QEMU_BUILD_BUG_ON with G_STATIC_ASSERT
  slirp: Move g_spawn_async_with_fds_qemu compatibility to slirp/
