Card in pa_source_info that is used as card-index is uint32_t so it
is never less then 0. Also index in GvcMixerCard is already unsigned
int that is used to compare with card-index. This fixes build
warning - comparison between signed and unsigned integer expressions.

GvcMixerStream id is unsigned int and starts with 1, so we can use
0 as invalid id. This fixes build error/warning - comparison
between signed and unsigned integer expressions.
Entries are only hidden when available == PA_PORT_AVAILABLE_NO, so if an
entry toggles between PA_PORT_AVAILABLE_YES and
PA_PORT_AVAILABLE_UNKNOWN (Bluetooth headset switching between HSP/HFP
and A2DP for example), this should not result in new entries being created.

The "uint" type is not defined for standard C, and building with
-std=c99 enable stricter conformance and results in compilation failing.
Use "guint" instead.
Right now, makes sure "Off" profiles are not added, because when selected,
the item will disappear and there's no way to get it back (because it
disappeared). In the long term, handling the "off" profile correctly
would be better.

This will allow to have different icons for internal audio cards
(which are flagged generically as "audio-card"), depending on which
port is in use (ie. headphones or speakers).
This requires the new icon information, which is only exported by
PulseAudio 3.0. If it's not available, we fallback to card icons
like before.
