Plugin interfaces have been discussed a few times in the past.  The 
concerns have been 1) they will be abused with the introduction of 
proprietary plugins 2) we would have tremendous difficulty maintaining a 
stable plugin abi 3) they would create stability issues in qemu because 
the plugin quality cannot be controlled.

For 3, it's a matter of getting a bug report of a crash in qemu with a 
random plugin module enabled.  How do we know whether the crash is 
really a qemu bug or whether it was an issue in the plugin?  This isn't 
so bad in dynamic languages like Python but it's a real pain in C.
