connection: Add purple_connection_take_error()

This patch adds a purple_connection_take_error() function, which
is functionally equivalent to purple_connection_g_error(), except
that it takes ownership of the passed GError.

This is useful to simplify error handling so that the GError doesn't
have to be freed, or, in the future potentially copied, if it's no
longer needed where it's generated. It can also allow for GErrors
being generated without storing them in a variable. This would be
reasonably common if/when all PurpleConnection errors are passed
in via GError.
