MEDIUM: stream-int: add a new function si_applet_done()
This is the equivalent of si_conn_wake() but for applets. It will be
called after changes to the stream interface are brought by the applet
I/O handler. Ultimately it will release buffers and may be even wake
the stream's task up if some important changes are detected.
It would be nice to be able to merge it with the connection's wake
function since it mostly manipulates the stream interface, but there
are minor differences (such as how to enable/disable polling on a fd
vs applet) and some specificities to applets (eg: don't wake the
applet up until the output is empty) which would require abstract
functions which would slow down everything.
