Cleaning up documentation in header files.
Renamed flags for filtering admin output (avoiding multiple responses per polling-step).
Disable liblo message queueing on admin and signal update servers; use timetagged bundle to transport /sync messages instead of including timetag in message; use double instead of float to represent elapsed time in /sync message.
Fixed monitor bug for autorequesting large numbers of signals or connections - since e62872b @ID has not been an extra parameter, so the functions on_signal_continue_batch_request() and on_connection_continue_batch_request() could not retrieve IDs.
Send batch-requested signals and connections in OSC bundles.
Bundle query responses and return with timestamp from query message.
Do not send empty bundles.
Added receiver data structure, which sits at the destination of a link and mirrors the router at the sending side. For now this object is intended for holding metadata on the link source and connections, information which is needed for sending remote instance release requests. In the future the receiver object could also help recover mapping state after a source crash, and may have an active role in processing datastreams and combining many-to-one connections.
Add a check for lo_bundle_count() to build against older versions of liblo.
Do not remove unscoped links.
Update ID map reference count when calling msig_match_instances().
Added receiver functions.
Merge branch 'master' into merge

Conflicts:
	src/admin.c
Finished basic integration of mapper_receiver data structure and functionality, including release of remotely-owned instances on scope removal or unlink. Also streamlined freeing of router structures.
Fix for problem with out-of-order packets and instance releases: id maps are not removed until reference count is 0 AND a timeout from last relevant remote release message has been received. During this timeout period remote messages matching the id map will not be processed.
Merge branch 'master' into receivers

Conflicts:
	src/types_internal.h
Properly release orphaned instances on unlink or disconnect; added scopes to receiver structure.
Added remote instance release request functionality: when an instance of an input signal is released locally (with a call to msig_release_instance), a release request message is sent to all upstream connected signal belonging to a link scoped for the instance. Output signals can optionally register an instance_management_handler (as before) but now a third argument specifies the type of events to call the handler for.
Remove obsolete function mdev_send_signal().
Add new metadata from repeated linkTo messages; use monitor to create links and connections in test.c
