For now, each posting list stores position/offset information for multiple columns. We may implement separate posting lists for separate columns at some future point. (CVS 3408)

surprising impact on performance, I believe because it keeps the index
smaller (by keeping rowids smaller), and also because it improves
locality in the table (deleting a row means we've already touched the
pages leading to that rowid). (CVS 3405)

in order to provide better error reporting. This is an interface change
for virtual tables. Prior virtual table implementations will need to be
modified and recompiled. (CVS 3402)

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)

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)

delimiters in an array and wrote things inline. Submitting this for
review separately because it's pretty standalone. (CVS 3378)
