627ecc44d2 Revert "os: reset Audio_out stream prior to calling start"
This reverts commit d8b95c263b.

Some clients might want to fiddle with the clients play position
(e.g. the mixer) within 'Audio_out::start()' and we might reset
it to an old value if we do it afterwards.

Fixes #1796.

6d1e417250 os: reset one packet further in Audio_out stream
Since all Audio_out server components loop over the packet stream
queue it is save to reset the tail position to one after the play
position. We have to do this because we do not know exactly when
the play position changes (i.e. the driver has processed the packet)
and we might end up with a tail position before the current play
position.

3f6ff39d76 os: improved label matching
This patch unifies the mechanism of selecting server-side policies and
taking session-routing decisions based on session labels. In both cases,
XML nodes are scored against session labels. The score depends on the
XML attributes 'label' (exact match), 'label_prefix', and
'label_suffix'.

e4678a4dc1 decorator: do not defer stacking changes
This patch changes the decorator to always apply stacking-order changes
immediately instead of deferring the re-stacking of the nitpicker views
to the next call of 'update_nitpicker_views'. The deferred application
did not always work when more then one windows changed their stacking
position at once because the cached '_neighbor' values interfered with
each other.

The eager re-stacking should not have negative effects on the user
experience because, in contrast to re-positioning, re-stacking a rare
operation.

acb0ddd9ef decorator: generalize include/decorator/window.h
This change makes it possible to reuse the generic window decorator
classes in include/decorator/ for decorators of a different structure.
E.g., instead of painting decorations on a single nitpicker session,
each window may paint its decorations into additional window-specific
nitpicker sessions.

a528aa097a init: add 'label' criterion for session routing
This patch introduces a shortcut for conditional session routes of the
form '<if-arg key="label" value="..."/>'. With this change, the label
can be directly specified as 'label' attribute of an '<any-service>' or
a '<service>' node. The '<if-arg>' mechanism was not documented anyway
and I hope to be able to ultimately remove it.

2b429ee84c base: Dispatch server signal in entry point
Currently, when a signal arrives in the main thread, the signal dispatcher is
retrieved and called from the main thread, the dispatcher uses a proxy object
that in turn sends an RPC to the entry point. This becomes a problem when the
entry point destroys the dispatcher object, before the dispatch function has
been called by the main thread. Therefore, the main thread should simply send an
RPC to the entry point upon signal arrival and the dispatching should be handled
solely by the entry point.
