[pvrusb2] Completely new fwextract.pl

[Mike Isely]

The new fwextract.pl is in good enough shape for others to try if 
interested.  Please grab from here:

Normal operation is the same as before.  But the internals are almost 
completely different.  Take a look at the program, specifically at the 
end of the file and you'll see how its firmware database is held now.  
The neat effect from this is that to apply "new" information to it, one 
only needs to append the additional records directly to the end of the 
script itself.

And now when you train it on a new driver package, it will also 
automatically look for instances of all previously known firmware 
images, not just the results of the manual extraction process.  This 
means that the training process can frequently succeed even if you skip 
all the tedious manual stuff up front!  (Yay!)

There's a lot of other stuff this program can do in support of its 
reorganization.  But if you're really curious poke around the code 
(search for "GetOptions" to see where the command line options are 
recognized).  I'll see about getting the online documentation updated to 
describe the new stuff.  But with that said, the existing documentation 
is pretty much still accurate, i.e. extraction works as before and the 
full training process still works (though the data it emits is much more 
compact now).
