This enhancement adds a user-configurable preference to provide a name
associated with a particular binary status ("word bit") returned from a
protective relay or controller.
This word bit is returned in an unsolicited message with an index position and
time-stamp but the user would previously have to manually consult a
index-to-name lookup table to determine which particular status had changed.
The optional user preference lets the end-user paste in a comma-separated list
of all the status names that will animate in the dissector tree alongside the
index position.
One question I had for this submission is regarding the different wmem memory
pools - wmem_file_scope vs. wmem_packet_scope. A previous function
(time_msecs_to_str) was already used near where I added the new functionality
and it used wmem_packet_scope, contained within the same iterative for loop. I
had to change this call over to wmem_file_scope to prevent memory stomping of
the new status word bit name array. This should probably be looked at by
someone with much more intricate knowledge of this library than myself.
