backends/flint/flint_alldocspostlist.h:
Implement posting lists which return a list of all documents in
the database.  Such a posting list is obtained by calling
Xapian::Database::postlist_begin() with an empty term (ie, "").
Also, all Xapian::Database methods which take a termname now
accept an empty term, and return appropriate values (ie,
get_termfreq("") and get_collection_freq("") return the number of
documents in the database, and term_exists("") returns true
unless the database is empty).
docs/quartzdesign.html: Document the inefficiency of all-document
postlists for Quartz.
tests/api_anydb.cc,tests/api_db.cc,tests/api_wrdb.cc: Add tests for
all-document postlists, and for passing an empty term to all the
applicable database methods.  This defines the new tests
allpostlist1, allpostlist2, emptyterm1, and emptyterm2.  These
tests currently skip for the remote backend where postlist_begin()
isn't yet implemented.
