New BiF record_field_vals() that returns the fields of a record in a

Browse source 
table with meta-information.

Example:

type r: record {
	a: count;
	b: string &default="Foo";
	c: double &optional;
	d: string &log;
};

event bro_init()
{
    local x: r = [$a=42, $d="Bar"];
    print record_fields(x);
}

This prints:

  {
  [a] = [type_name=record, log=F, value=42, default_val=<uninitialized>]
  [b] = [type_name=record, log=F, value=<uninitialized>, default_val=Foo],
  [c] = [type_name=record, log=F, value=<uninitialized>, default_val=<uninitialized>],
  [d] = [type_name=record, log=T, value=Bar, default_val=<uninitialized>],
  }

This is one more step in Seth's quest for full inspection support. :-)
