fix to macro_copy() function of epan/dfilter/dfilter-macro.c.
Attached is a patch for bug 2068.
There were several problems found in the macro_copy() function of
epan/dfilter/dfilter-macro.c.
#1: The size of the d->parts array cloned from m->parts was one pointer too
short (missing the final NULL pointer).
#2: The d-parts array cloned from m->parts was referencing pointers into the
original m->priv and not into the new d-priv.
#3: The d->priv string cloned from m->priv did not include all the string
sections from the original m->priv.
The patch includes a new DEBUG_MACRO which can be used to dump to stdout the
contents of the various dfilter_macro_t structs at various execution points.
This DEBUG_MACRO functionality can be enabled be uncommenting the /* #define
DUMP_DFILTER_MACRO */ line near the top of the patched dfilter-macro.c file.
