The latency offset type should be signed (int64_t) so we can also add
a negative latency offset.
This also includes changing the type of the sink/source
offsets and updating pacmd so it handles negative numbers.
A latency offset variable was added to the port struct and a function to
set the latency offset.
The latency offset does nothing for now, but it will be later added to
the sink/source latency.
Without this fix, errors about previous definitions are generated in
numerous locations.
Example of error:
CC libpulsecore_1.98_la-auth-cookie.lo

../../src/pulsecore/core.h:29:24: note: previous declaration of

Overall it would be nicer if we could avoid this kind of fix, but it
would require further reorganisation that I'm not prepared to undertake
right now.
The recommended way of setting available status is to call
pa_device_port_set_available, which will send a subscription event
to the relevant card. It will also fire a hook.

This forms the base for being able to expose all ports of all
profiles (even inactive ones) to clients.

Since both cards and sinks can hold references to a port, it makes
sense to reference count them. Although no current implementation
actually has sinks with ports but without a card, it felt wrong
to make it harder to make such an implementation in the future.
