[Gpsbabel-code] [patch] Support for Honda/Acura Navigation System VP Logs (.vpl)

[Chris T. <gps...@ad...>]

Hello,

 	Attached is a patch to the latest CVS that adds read support for 
the VP logs (.vpl files) produced by factory-installed Honda/Acura 
Navigation Systems.  (Manufactured by Alpine)  I know it works with 2006 
Honda Civics, and it likely works with newer Civics and TL's as well.  In 
theory it might work with the nav systems in other models going back as 
far as 2004, based on some indirect documentation I've seen via Google. 
It might also work on non-Civic/TL models, provided their nav systems are 
sourced by Honda from Alpine.  (I'm guessing it won't work on 
non-Honda/Acura cars, but who knows)

 	The attached patch includes a reference file that I've santized 
somewhat.  I've not entirely decoded all the sentences in the logs, and 
I'm guessing some of them might contain identifying information about the 
car from which they were taken.  As such, I've stripped out all extraneous 
sentences, leaving only the '75's.  (Which are all the format parses 
anyway)

 	Been a long while since I programmed in C (and never with any 
mastery), so please feel free to suggest improvements/changes.

 	Thanks,

 	Chris
