PPP: Optimize write buffer management
Extend the write buffer handling in gathdlc.c to minimize stalling and
process switching during large PPP transfers. The single write buffer
is replaced by a queue of buffers, allowing for much larger emission
windows without hugely impacting memory consumption. This reduces the
time required to send 50 MB between a couple of local PPP interfaces on
my laptop from ~53s to ~3s.
