If a device is capable of waking the host system from suspend, it should
be marked as wake capable. We introduce a new management operation here
to set this property and implement the API needed to call it. We also
add the dbus endpoint to allow the wake capable setting to be
controlled.
---
Changes in v3:
* Added profile_wake_support and made wake_capable dependent on it
Changes in v2:
* Added dbus api "WakeCapable" to set value
* Update device_set_wake_capable to be called by
adapter_set_wake_capable_complete so we can emit property changed

Shouldn't there be a way to check if the kernel does actually support
the command first? We shouldn't be attempting to use it with kernels
that don't support it and the property should also not appear in that
case, so it is only visible if:
1. Kernel reports that Wake Capable command is supported
2. A driver/plugin/profile calls device_set_wake_support
Also in case those 2 conditions are attended bu the command fails we
should reply with an error since there won't be any PropertiesChanged
to indicate something went wrong.

That sounds reasonable. Are all supported management apis reported
somewhere? (I may discover the answer to this just by reading code)
Also, what's a good way to report an error on PropertiesChanged? Just
logging the error (i.e. error("Failed to set wake capable property"))
or actually calling something like g_dbus_emit_property_error (I don't
think this is real; just using an example)?
