fb6794360d Write doclists using a segmented technique to amortize costs better. 
New items for a term are merged with the term's segment 0 doclist,
until that doclist exceeds CHUNK_MAX.  Then the segments are merged in
exponential fashion, so that segment 1 contains approximately
2*CHUNK_MAX data, segment 2 4*CHUNK_MAX, and so on. (CVS 3398)

b2f4d0173a Make fts1.c not rely on nul-terminated strings. Mostly a matter of 
making sure we always pass around ptr/len, but there were a few places
where we actually relied on nul-termination.

An earlier change had additionally changed appropriate
sqlite3_bind_text() calls to sqlite3_bind_blob().  I've found that
this changes what's actually stored in the database, so backed those
changes out.  Also (and this is weird), I found that I could no longer
do straight-forward = queries against %_term.term at a command-line. (CVS 3379)

5db455e7b5 Refactor the FTS1 module so that its name is "fts1" instead of "fulltext", 
so that all symbols with external linkage begin with "sqlite3Fts1", and
so that all filenames begin with "fts1". (CVS 3377)
