24e289d025 experimentally move savevm-async back into a coroutine 
Move qemu_savevm_state_{header,setup} into the main loop and
the rest of the iteration into a coroutine. The former need
to lock the iothread (and we can't unlock it in the
coroutine), and the latter can't deal with being in a
separate thread, so a coroutine it must be.

284d3b2cab security patches for libslirp CVE-2020-8608 
original commits and email can be found here[0]

A out-of-bounds heap buffer access issue was found in the SLiRP
networking implementation of the QEMU emulator. It occurs in tcp_emu()
routine while emulating IRC and other protocols due to unsafe usage of
snprintf(3) function.

A user/process could use this flaw to crash the Qemu process on the host
resulting in DoS or potentially execute arbitrary code with privileges
of the QEMU process on the host.

ee8bd5bfbe add patch for CVE-2019-20382 (vnc disconnect memory leak) 
oss-security email can be found here[0]

upstream commit here[1]

this effects our vncproxy. dominik and me tested if the issue is present
on our branch and it appears that it is.
in essence when we disconnect from a vnc connection, the memory isn't
free'd afterwards which causes the qemu process to use more and more
memory with each disconnect, which could lead to a dos scenario.

we tested the patch and it seems to mitigate the problem.
