267391c8fd protocol: learn to describe fd passing in messages
Add a new type, "unix_fd", used to describe file descriptor sharing via
socket ancillary data (these messages are local only).

The marshaller/demarshaller can't serialize this in memory (consume_fd
implementation is empty), so it is the responsability of the marshaller
user to handle sending and receiving the handles, which are appended at
the end of the message with an extra stream byte (because some Unix
requires sending at least a byte with ancillary data).

Even if there is no fd to send (or if the fd is invalid etc), the
receiver side expects an extra byte anyway.

4a2a996674 codegen: Import six module before first use
The module is used in the initial try/except so make sure it is
already imported.

e919337980 Make spice_codegen.py work on both Python 2 and 3
This is a new version of my previous patch that does not include six.py.
It's still kind of big, but at least it's all spice-common changes now.
There are also a few other fixes that Christophe brought to my attention.
Note that six now needs to be installed on the system (python-six on
Fedora and Debian, six on PyPI).

This *should* be enough to make spice_codegen.py work on both Python 2
and Python 3.  The major changes are as follows:

 * cStringIO.StringIO -> io.StringIO
 * str vs. unicode updates (io.StringIO doesn't like str)
 * integer division
 * foo.has_key(bar) -> bar in foo
 * import internal_thing -> from . import internal_thing
 * removed from __future__ import with_statement
   (might break Python 2.5?)
 * changed some lambdas to list comprehensions (done by 2to3)
 * cast some_dict.keys() to list where needed (e.g. for sorting)
 * use normal type names with isinstance instead of types.WhateverType

0067c31bad allow attributes on channel elements in .proto files
We want to be able to add an @ifdef annotation to optional messages
For example, we want to compile in the smartcard messages only if
libcacard is available

a11615f713 add check for pyparsing
Check both in configure.ac (after checking if we need to rebuild
the marshalling files) and in the python script using pyparsing
(for people modifying .proto files in tarballs)

0ed056da99 Properly parse QXLImage to the new-world SpiceImage
SpiceImage now replaces RedImage and has all image types in it.
All image data are now chunked (and as such not copied when demarshalling).

e42c910b5c Store SpicePath segment count rather than size
Internally and in the network protocol (for the new version) we
now store the actual number of segments rather than the size of the
full segments array in bytes. This change consists of multiple changes
to handle this:

* Make the qxl parser calculate num_segments
* Make the canvas stroke code handle the new SpicePath layout.
* Fix up is_equal_path in red_worker.c for the new layout
* replace multiple calls to spice_marshall_PathSegment with a single
  spice_marshall_Path call
* Make the byte_size() array size handling do the conversion from
  network size to number of elements when marshalling/demarshalling.
* Update the current spice protocol to send the segment count rather than
  the size
* Update the old spice protocol to use the new byte_size functionallity
  to calculate the size sent and the number of elements recieved

b1dc7fae2a Initial import of spice protocol description and demarshall generator
The "spice.proto" file describes in detail the networking prototcol
that spice uses and spice_codegen.py can parse this and generate
demarshallers for such network messages.
