Log message (8 lines):
api/postingsource.cc,include/xapian/postingsource.h: Add a new
built-in posting source, FixedWeightSource, which returns every
document in the database, but with a fixed weight.  In
particular, this is useful to add a constant weight to every item
in a subquery.  Also, in ValueWeightPostingSource, refactor the
"last_docid" member to a bool "started", since this is all it's
used for.
tests/api_db.cc: Add fixedweightsource1, to test FixedWeightSource.
