On Arch Linux x86_64, gcc 7.2.0-3, -Og -g3:
gstdevicemonitor.c: In function ‘bus_sync_message’:
gstdevicemonitor.c:276:8: error: ‘matches’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This commit also simplifies the code a bit.

gst_structure_id_get() returns a new reference so the returned device is
actually (transfer full).
The code using this API was already correct but the code example in
comments was not.

If no providers for a particular class could be found, then removing unmatched
filters would cause all devices to be returned instead which is not at all what
the user intended. We still return 0 for unmatched filters.
Add methods to add/remove the providers that should be hidden by this
provider. Also make a method to get a list of hidden providers.
This makes it possible to have multiple systems monitor the same devices
and remove duplicates.
Add a property to see all devices, even duplicate ones from hidden
providers.
Release the monitor lock when calling the provider start/stop methods.
Because we release the lock now, We need to make sure we check the
cookie again and keep track of started and removed providers.
The deviceproviders are added to the array sorted by their rank. Make
sure we keep this ordering when removing a provider.
We use _prepend to collect the devices, use g_list_reverse to get the
devices in the right order; sorted by rank and in the same order as
returned by the provider.
So from this point, the remaining warning for libgstreamer are about
protected member not showing in the doc. This may need some discussion
with upstream gtk-doc people.
* Remove % in from of none macro
* Fixed GST_TYPE_FAGS -> GST_TYPE_FAG_SET
* Minor wording fix
* Can't link to GstUri.port, so split the .port part
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.
Also normalize booleans in a few places.
