In some newer Linux distributions, env python default to Python 3.0. This
patch explicitly uses "python2" instead of just "python" for all scripts
that use #!

This patch moves the code for opening an input protobuf packet trace into
a function defined in the protobuf library. This is because the code is
commonly used in decode scripts and is independent of the src protobuf
message.
This patch changes the decode script to output the optional fields of
the proto message Packet, namely id and flags. The flags field is set
by the communication monitor.
The id field is useful for CPU trace experiments, e.g. linking the
fetch side to decode side. It had to be renamed because it clashes
with a built in python function id() for getting the "identity" of an
object.
This patch also takes a few common function definitions out from the
multiple scripts and adds them to a protolib python module.
This patch simplifies the usage of the packet trace encoder/decoder by
attempting to automatically generating the packet proto definitions in
case they cannot be found.
This patch adds a simple Python script that reads the protobuf-encoded
packet traces (not gzipped), and prints them to an ASCII trace file.
The script can also be used as a template for other packet output
formats.
