The wireshark protocol dissector is a bit out-of-date. Several new channel types
and enums have been added. It would be nice if these values (and the
translation between the value and the name) could be automatically generated so
that updating the dissector was a slightly less manual process. This patch adds
a commandline switch which generates both the enums and value-name lists in the
format that wireshark expects.
Fixes the resulting enums.h from the invocation of:
./spice_codegen.py --generate-enums spice.proto spice-protocol/spice/enums.h
Right now any enum will contain None as the enum members, with this fix
it will contain the real enum members, i.e. SPICE_FOO.
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
With the new usbredir code we have the new concept of the abstract /
generic spicevmc channel type (which just tunnels data from a qemu chardev),
and we've the usbredir channel, which is the only current user of this.
This was reflected in the protocols enum in spice-protocol.h by a manual
edit done by me, my bad. This patch teaches spice.proto about the relation
between the abstract spicevmc channel and the usbredir channel and
modifies codegen to deal with this.

Commit 9d5ef9beeca722b2ceff7d15aaa3aaaaf07ecfbf in spice-protocol
introduced a typedef manually in the generated enums.h header.
This patch adds them automatically to all enums during enums.h generation.
This means the member is not sent on the network at all.
Instead its initialized to the attribute argument when demarshalled.
This is useful for backwards compatibility support.
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.
