ChangeLog

2016-07-07  john  <john@asus>

	* Tag_Foray.cpp: refactor clock fixing logic into new class
	Clock_Repair, and subsidiary classes Clock_Pinner and
	GPS_Validator. Fix it to work for pulse timestamps from
	CLOCK_MONOTONIC.  All clock corrections now happen in the tag finder,
	so R harness code needs to drop that logic.

	* find_tags_motus.cpp: call Tag_Database::load_ambiguity() to restore
	Ambiguity map from database; could instead add Tag_Database * to c'tor
	for DB_Filer

	* Ambiguity.hpp, Ambiguity.cpp: extend newProxy to allow specifying the
	proxyID, as when reconstructing a group from the database; make this
	method public so DB_Filer class can do that.

	* Tag_Foray.cpp (pause, resume): don't serialize/deserialize Ambiguity
	map as part of batch pause/resume; instead, maintain a global tagAmbig
	table in receiver DB

	* Tag_Database.hpp, Tag_Database.cpp: include getTagForMotusID in
	RELEASE build for use by DB_Filer::load_ambig

	* DB_Filer.hpp, DB_Filer.cpp: replace previous Ambiguity-related
	methods with new methods save_ambiguity() to save a single ambiguity
	group and load_ambiguity() to restore all existing ambiguities from the
	database
