[Gnash] updated plugin

[Rob Savoye]

I just checked in a newer version of the plugin code that's nice and 
stable. It turned out I got caught up in an unrelated Firefox bug that 
got fixed yesterday or so in CVS. Now that my development version of 
Firefox is stable again, I tweaked the plugin to also be completely 
stable, and cause no weird side effects, all of which would crash the 
browser. Now it's stable enough to use for my general browsing, although 
it doesn't do anything useful yet.

This version displays a hard-coded OpenGL graphic in the window where 
the flash movie is supposed to be playing. You'll get multiple graphics 
if you have multiple flash movies in the same window frame. All the 
flash movies get downloaded to /tmp, so they can be used for testing 
with the standalone player.

Once the flash movie is downloaded, it starts a thread to play the 
movie, so the movie's run loop needs to run separate from Firefox's. 
Today I plan to merge the rest of the standalone player into this 
thread. Initially I'm planning on downloading a movie and then playing 
it, as this will require the least amount of nasty changes to the 
standalone player. Once that works, the next step will be to start 
playing the movie while downloading it. This will require major 
rearrangement of how Gnash reads the input stream, but these will all be 
worthwhile changes. Right now Gnash expects to sequentially read a disk 
based file, whereas with Firefox, the input is a callback, and input 
comes in batches.
