[Speex-dev] Ugly way to save and restore echo-state

[Ard van Breemen]

Heh,
It is simple, but it seems to work more or less.
Since I control the adapt_rate from my application, it will work
ok. But people using the plain library might want to reset the
cancel count after loading. If you set the cancel count back at
0, it will not adapt for the first 4 frames or so.

Anyway, read and shiver. It is a quick hack I know :-)

But the need to be able to save and restore filter settings
remain I guess.
