370a43de83 tap-vsockd: allocate payload separately for better alignment 
Previously we allocated `sizeof(struct ring) + size`. This patch
allocates `sizeof(struct ring)` and then `size` for the payload
separately. Hopefully the payload will be better aligned.

3fc0d994b5 tap-vsockd: add buffering 
This patch adds a simple ring buffer implementation and uses it to buffer
the reads and writes to/from the AF_HYPERV socket and tap file descriptor.

This removes the need to perform small reads and writes for the per-packet
headers and allows a read on the Hyper-V socket to block at the same time
as a write to the tap device (and vice-versa)

The configuration in the init.d script is:

- a max message size (individual read or write) of 8192. Experimentally
  this seems to be the largest completely reliable size across the Windows
  versions we can support. Messages of length 16384 sometimes fail.
- a buffer size of 256KiB in each direction.

Single stream TCP throughput as measured by iperf increases modestly, by
another 100Mbit/sec.

These never got an interface on any platform, and I don't think they
ever will, we can increase global limits or you can set something
with a privileged container. Can add back later if required.

40a3b5578a Always have database at /Database 
Use a bind mount for OSX and Windows for 9p filesystem.

This makes it easier to use a different database source,
and to share database into system containers.

In most places we use the Alpine one, which is already here, but
make sure this is updated, as we may use it more (yes, we should be
consistent).

Change the hash to just use the ca-cert hash, not the apt hash.
