Automatically generate a function to call the register routines for all 

protocols (idea shamelessly stolen from GDB).  We require that the
register routines

	1) be located in "packet.c" or in one of the "packet-XXX.c"
	   files;

	2) have a name of the form "proto_register_XXX";

	3) take no argument, and return no value;

	4) have their names appear in the source file either at the
	   beginning of the line, or preceded only by "void " at the
	   beginning of the line;

and we require that "packet-XXX.c" files be added to "DISSECTOR_SOURCES"
in "Makefile.am".

# Build "register.c", which contains a function "register_all_protocols()"
# that calls the register routines for all protocols.
#
# We do this by grepping through sources. If that turns out to be too slow,
# maybe we could just require every .o file to have an register routine
# of a given name (packet-aarp.o -> proto_register_aarp, etc.).
#
# Formatting conventions: The name of the proto_register_* routines must
# start in column zero, or must be preceded only by "void " starting in
# column zero, and must not be inside #if.
#
# We assume that all dissector routines are in "packet-XXX.c" files,
# or in "packet.c".
