[PATCH] Titles for OS data types

[Stan Shebs <stanshebs at earthlink dot net>]

Per Vladimir's request in 
http://sourceware.org/ml/gdb-patches/2012-06/msg00003.html , here is a 
patch to Linux OS data that adds a new column "Title". Titles are 
arbitrary strings just like the existing type and description columns, 
but are informally understood to be short descriptions that are suitable 
for menu items, window titles, etc, in a GUI like Eclipse.  Since they 
can clutter up command-line output, the "info os" command omits the column.

Filtering by looking for a column literally named "Title" is a bit hacky 
but hard to do more cleanly, as "info os" is designed to mindlessly 
repeat whatever platform-specific xfer code delivers up.  Still, a 
general mechanism of metadata for columns is certainly overkill for this 
rather specialized case.  I've also omitted a NEWS mention since it only 
affects -info-os, which is itself new.

I'll commit this in a couple days if nobody has any objections.
