Add g_main_context_ref_thread_default(), which always returns a
reffed GMainContext, rather than sometimes returning a (non-reffed)
GMainContext, and sometimes returning NULL. This simplifies the
bookkeeping in any code that needs to keep a reference to the
thread-default context for a while.

* Add 'invoke' style method, which can be used to call an interaction
from any thread. The interaction will be run in the appropriate
#GMainContext
* Sync methods can be called whether main loop is running or not.
* Derived classes can choose to implement only sync or async
interaction method, and the invoke method will fill in the blanks.
* Documentation for the above.
* Tests for the above.

* Add cancellable argument to g_tls_interaction_ask_password
and g_tls_interaction_ask_password_async.
* This is API breakage, but this API has not yet been released
in a stable release (and very unlikely used yet).
* Since we're breaking unreleased API, expand amount of padding
on GTlsInteractionClass because we're going to need it.

The database is an abstract object implemented by the various TLS
backends, which is used by GTlsConnection to lookup certificates
and keys, as well as verify certificate chains.
Also add GTlsInteraction, which can be used to prompt the user
for a password or PIN (used with the database).
