f40a504164 When gathering a doclist for querying, don't discard empty position lists until the end; this allows empty position lists to override non-empty lists encountered later in the gathering process. This fixes #1982, which was caused by the fact that for all-column queries we weren't discarding empty position lists at all. (CVS 3433)

4240240f12 Re-use deleted rowids for new segments. This has a somewhat
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)

fe1368ee08 Add a new zErrMsg field to the sqlite3_vtab structure to support returning
error messages from virtual table constructors.  This change means that
virtual table implementations compiled as loadable extensions for version
3.3.7 will need to be recompile for version 3.3.8 and will not be usable
by both versions at one.  The virtual table mechanism is still considered
experimental so we feel justified in breaking backwards compatibility
in this way.  Additional interface changes might occurs in the future. (CVS 3401)
