b5f94870c2 Re-used prepared statement from fts3 cursor. Previously, each call to 
fulltextFilter() finalized any existing prepared statement and
prepared a new one.  In the case where idxNum has not changed, simply
reseting the statement suffices.  This provides an order of magnitude
speedup in incoming joins against docid. (CVS 5489)

c2c66a030d Delete all fts3 index data the table becomes empty. Previously, 
deleting all rows from an fts3 table would leave a bunch of index data
describing the terms of the original data, plus deletions of those
terms, perhaps with some amount of it merged together so the deletions
knocked out the originals.  Even when all rows were deleted that
original data would hang out, though eventually it would mostly be
overwritten if new data contained the same set of terms. (CVS 5413)

6c106e3f3b fts3 functions for testing scripts. These are a first step towards 
being able to write test script which verify that fts3 is internally
building indices in the expected way.  Both new functions are only
defined if fts3.c is compiled with SQLITE_TEST defined, as when
building testfixture.  These functions are not intended to be part of
the exposed fts3 API.

dump_terms() generates a TEXT result of all the terms in the index (or
a specified segment), sorted and joined with spaces.

dump_doclist() generates a TEXT representation of the doclist
associated with a given term in the index (or a specified segment). (CVS 5340)

b6a75606ed Change prefix search from O(N*M) to O(NlogM). The previous code 
linearly merged the doclists, so as the accumulated list got large,
things got slow (the M term, a fucntion of the number of documents in
the index).  This change does pairwise merges until a single doclist
remains.  A test search of 't*' against a database of RFC text
improves from 1m16s to 4.75s. (CVS 4599)
