[Gnash-dev] plugin update

[Rob Savoye]

I just checked in changes that makes the plugin use Mozilla's NSPR API 
for mutexes, conditional variables, and threads, because they work 
better from within Firefox than using SDL. SDL was just getting to be 
one more layer on top of a mess of event loops and other things... Now 
the threads all cleanup after themselves correctly. There is still 
probably a little debugging to be done on thread synchronization, so I 
wouldn't start filing bug reports on it yet.

The player is enabled, and it plays movies, but I still get the triangle 
and square for some reason. Since nothing crashes, I figured why not 
leave it enabled. Maybe another set of eyeballs will see what happens to 
the image...

I also changed the debug logging system around. Now by default it 
doesn't produce the disk based debug log, which can get huge. To get the 
disk log, you have to use the "-w" option to the standalone player. "-v 
-v" will print all the TRACE messages to the terminal.

For the plugin, it writes the disk file by default, since it's handy to 
make sure the movie is playing correctly, even if it won't display. If 
launched from a menu or icon, it goes in your home directory, otherwise 
the current directory.
