Lookup uris, delete, aggregation rules, untyped, sharing.

ContactsListView: combined together various import/export
menus under single dialog, hiding SIM import when no ICC
present.  Switched almost all cases to use soft "lookup"
uris, especially for pick and operation cases.  Brought
back delete in long-press menu, and pick modes needed for
SHOW_OR_CREATE.  These partially fix http://b/2096050 and
http://b/2096870 and http://b/2102632

ViewContactActivity: changed menus to inflate from XML,
added "Share" option to replace barcode.  Confirmed that it
sends vCard through Gmail, other apps can match MIME-type
to begin appearing in picker.  Changed EAS rules back to
untyped for Email and IM, which now allows use to use IM
type as protocol picker.  Fixes http://b/2072731 and
http://b/2092744 and http://b/2088935

EditContactActivity: restructured editing to front-load all
version assertions, and perform as single batch to prepare
for reparenting.  Correctly generate AggregationExceptions
using new API from dplotnikov, especially in cases where we
create multiple RawContacts from scratch.  Unit tests to
verify exceptions built correctly for edge cases.  Also
showing toast when saving failed.  These changes were mostly
untracked, but fixes http://b/2099211

Various untracked NPE related to untyped HardCodedSources
and cleanup of "tel" "smsto" and SMS MIME-type constants.
