[Qemu-devel] [PATCH v5 0/1] qemu-ga: add guest-get-osinfo command

["Tomáš Golembiovský" <tgolembi@redhat.com>]

v5:
- fixed build failure with older glib
- fixed coding style issues
- fixed one log string

This is a continuation of the work started by Vinzenz Feenstra in the
threads:

The idea is to report some basic information from uname and from
os-release file, if it is present. On MS Windows, where neither uname
nor os-release exist we fill the values based on the information we can
get from the OS.

The example output on Fedora is:

{
  "return": {
    "kernel-version": "#1 SMP Mon May 8 18:46:06 UTC 2017",
    "kernel-release": "4.10.15-200.fc25.x86_64",
    "machine-hardware": "x86_64",
    "id": "fedora",
    "name": "Fedora",
    "pretty-name": "Fedora 25 (Server Edition)",
    "version": "25 (Server Edition)",
    "variant": "Server Edition",
    "version-id": "25",
    "variant-id": "server"
  }
}

The example output on MS Windows 10 is:

{
  "return": {
    "kernel-version": "10.0",
    "kernel-release": "10240",
    "machine-hardware": "x86_64",
    "id": "mswindows",
    "name": "Microsoft Windows",
    "pretty-name": "Windows 10 Enterprise",
    "version": "Microsoft Windows 10",
    "version-id": "10",
    "variant": "client",
    "variant-id": "client"
  }
}

One issue I see with the current implementation is that one is not able
to distinguish between various (non-linux) POSIX systems from the
returned values. That's because without os-release file (which I assume
is not common on non-linux platforms) only kernel-version,
kernel-release and machine-hardware are returned and telling what OS is
running there is a guessing game. Is this a problem?

Also the qapi documentiaton probably need some polishing. Unfortunately,
so far I was unable to get qapi parser satisfied and still include all
the important information.
