Make PurplePluginProtocolInfo definitions consistent

Since we can't use C99 structure initialisers, we have to manually add
new NULL fields to all protocols whenever we extend the structure.

Make it slightly easier to script that, by making the current last
field (get_cb_alias) consistent in all cases. In particular, there's
no reason *not* to have the trailing comma, as most already do.

Now I can add a new field to the PRPL by doing something like this...

PROTOFILES=`grep -rl '[A-Za-z_][A-Za-z0-9_]*,[[:space:]]*/\* get_cb_alias \*/' libpurple/protocols/ `
sed '/\/\* get_cb_alias \*\//{p;s/[A-Za-z_][A-Za-

# This program takes a C source as the input and produces the list of

# all signals registered.

# Output is:

# <arg name="new_value" type="b"/>

# </signal>

from __future__ import absolute_import, division, print_function

import re

import sys

# that it does not break "make" with the configure option

"dbus-method-called",

]

registerregex = re.compile("purple_signal_register[^;]+\"([\w\-]+)\"[^;]+(purple_marshal_\w+)[^;]+;")

nameregex = re.compile('[-_][a-z]')

print("/* Generated by %s. Do not edit! */" % sys.argv[0])

print("const char *dbus_signals = ")

for match in registerregex.finditer(sys.stdin.read()):

signal = match.group(1)

marshal = match.group(2)

if signal in excluded:

continue

signal = nameregex.sub(lambda x:x.group()[1].upper(), '-'+signal)

print("\" <signal name='%s'>\\n\"" % signal)

args = marshal.split('_')

# ['purple', 'marshal', <return type>, '', args...]
