Make seek information part of the xfer metadata, rather than an entirely
...
separate xfer method.
Add missing .alloc_iob entries to several xfer_interface_operations
structures.

Unplug before sending close() message, to avoid screwing up interfaces
...
which respond to close with a reopen() (e.g. iSCSI).

Remove xfer_ready() (it has been replaced by xfer_window())

Separate the "is data ready" function of xfer_seek() into an
...
xfer_window() function, which can return a scalar rather than a
boolean.

Add concept of transfer metadata, to be used by UDP in order to
...
implement sendto()/recvfrom() equivalents.

Modify data-xfer semantics: it is no longer necessary to call one of
...
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own
process), or otherwise arrange to be called. TCP does this by
starting the retry timer immediately.
Add some debugging statements.

Do not hold self-references. This then avoids the problem of having to
...
ensure that we only drop our self-reference exactly once.
To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.

in code defining reference-counted objects.
