raop: Use the port supplied by avahi when connecting to RAOP devices.
The Apple TV for example uses a non-default port, but we previously ignored
this. We now correctly parse the server string but in so doing, we end up
parsing the address twice. As we need a pure IP/hostname of the device itself
to use in our requests, this is somewhat unavoidable.
Sadly there are still other problems with Apple TVs, but this is still
one step closer.

formats: Export more functions needed for a clean build.
All of these functions are not actually defined in format.h
(they are defined in internal.h) and thus should really be
included only in libpulsecommon and implemented in a separate
source file.
However if that approach was taken, and these functions were
included in libpulsecommon, then they would have a link time
dependancy on libpulse (as these four functions use other
pa_format_info_* functions). As the opposite is already true
(libpulse depends on libpulsecommon), this is not possible as
it creates a circular dependancy.
Thus the only option is to just to include these four functions
in the map-file, but not actually export any public headers for
them. Of course users could use this implementation by defining
them in their own headers, but the only practical problem
with this approach is naming conflicts which is unlikely to happen.

functions.
Also ensure we export pa_format_info_from_string() for external use.

device-restore: Simplify the migration of data to per-port keys.
Rather than write all the keys out for each port, simply write a 'null'
port entry and modify the read code to 'fallback' to this when it cannot
find a key. This is needed as the code used when writing the key may not
actually have the sink ports available at the time it uses them,
and thus can cause a segv. This approach adds some degree of overhead
but it's relatively minimal and it can be mitigated by compiling
without support for legacy database formats if so desired.
