This patch adds the code necessary to perform basic buffer sampling for
HW voices. Includes new register definitions, support for a few new
methods, envelope stepping, ADPCM decoding, and the individual voice
buffer sampling to be added to the VP output mixbufs. This code does not
add system audio playback nor streaming support.
Some portions are disabled as they will need to be fixed up for
compilation in this new tree.
This code originates from Jannik Vogel's 2017 audio branch. Copied into
the current, recently LGPL-licensed version of this file with
permission.

For XQEMU, we do not currently use dotted-version notation style
tag names, instead we simply use the raw commit-id. This returns
the Makefile to the simple commit-id style.
The ObjectInfo struct has a variable length array containing the UTF-16
encoded filename. The number of characters of trailing data is given by
the 'length' field in the struct and this must be validated against the
size of the data packet received from the guest.
Since the data is UTF-16, we must convert the byte count we have to a
character count before validating. This must take care to truncate if
a malicious guest sent an odd number of bytes.

With an external data file, preallocate_co() must write the final byte
to the external data file, not to the qcow2 image file.
This is harmless for preallocation of newly created images (only the
qcow2 file size is increased to the virtual disk size while it should be
much smaller), but with preallocated resize, it could in theory cause
visible corruption if the metadata of the image is larger than the data
(e.g. lots of bitmaps).

Commit 767abe7 ("chardev: forbid 'wait' option with client sockets")
is a bit too strict. Current libvirt always set wait=false, and will
thus fail to add client chardev.
Make the code more permissive, allowing wait=false with client socket
chardevs. Deprecate usage of 'wait' with client sockets.

It turns out that having options listed in three places continues to be
a bad idea. I'm still toying with the idea of an improved infrastructure
here, but in the meantime, another bandaid.
There are three locations:
(1) .hx file, formatted as texi
(2) .hx file, formatted as human readable.
(3) .texi file, as section headers, formatted as texi.
You can compare the two summaries within the .hx file like so:
Human-readable command summaries:
`./qemu-img --help | grep 'Command syntax' -A14`
Detokenized texi command summaries:
`grep "@item" qemu-img-cmds.hx | sed -E 's|@var\{([^\}]*?)\}|\1|g'`
You can compare the two separate texi summaries like so:
Texi command summaries:
`grep "@item" qemu-img-cmds.hx"`
Texi command headers:
grep -E "@item.*@var" qemu-img.texi | tail -14

On some systems wchar_t is "long int", on others just "int".
So go cast to "long int" and adjust the printf format accordingly.

Here's a last minute pull request for 4.0. Turns out my last pull
request, to fix a regression in extended config space access for the
pseries machine didn't fix things hard enough. This PR has a single
patch which improves the fix to work in more cases.
It's a ghastly, ghastly hack, but it's simple and localized. I
already have patches almost ready to go in 4.1 that provides a simpler
and cleaner solution to all this.
