Oh, you bet your bippie, all of the local variables are getting changed
in the filter code (style changes be damned).  =)  I'm also planning on 
switching the style of the filter to match our "typical" filter code -
this will make it easier to understand, hopefully.

FWIW, I'm planning on implementing it like so:

if it is readbytes==0 (getline behavior), 
    read a chunk of data via ap_get_brigade
    decrypt it
    search for LF
    if match
        setaside remainder into local context.
        return the brigade
    repeat until we find LF
if it is readbytes!=0,
    call ap_get_brigade for that amount of data.
    decrypt the brigade.
    return the brigade. 
    (Note that I think we may end up returning less than is requested
     oftentimes, but that is definitely be permitted in our architecture - 
     just never return more than we ask for...)
I don't think we should support readbytes==-1 or peek just yet.

The only thing this means is that SSL_IN can be added at any point,
but it can't be removed once it has been added (since it will have
some buffering).  I don't think that'll be a problem though - I
know you can Upgrade a request to SSL, but I don't think you can
downgrade a request.  If that is the case, we need to think this
over some more...
I have class at 2PM, so I hope I can get something working out 
before I need to go to class...  -- justin
