448aa6f71a The uninitialized file descriptor from the unixFile structure is passed to sqlite3DetectLockingStyle in allocateUnixFile rather than the file descriptor passed in. This was causing the locking detection on NFS file systems to behave somewhat randomly and the result was locks were not respected and data loss could occur. (CVS 3508)

http://www.sqlite.org/cvstrac/tktview?tn=2036,35 describes some cases
where we were passing memset() a length which was the sizeof a
pointer, rather than the structure pointed to.  Instead, wrap this
idiom up in CLEAR() and SCRAMBLE() macros. (CVS 3488)

87f1d16bdb Replace the DocList and DocListReader structures. The new structures 
distinguish reading from a static buffer from writing to a dynamic
buffer.  This allows n-way doclist merging, and in-place merging of
segment leaf nodes, which together cut segment merge times in half. (CVS 3486)

9289cba076 Don't store empty segments. When inserting empty strings, the code 
was writing out a segment made up of a single leaf node containing the
\0 header.  LeafReader assumed that leaf nodes always contained at
least one term, so assertions would fail.

While it would be possible to support reading and merging empty
segments, there's no reason to do so.  While this change could have
been done in writeZeroSegment(), I put it in leafWriterFlush() so that
it would work right if segmentMerge() created an empty segment, which
could happen with future changes to how deleted documents are handled. (CVS 3484)

8a235d4d3b Convert fts2 to store data in a way which allows for much faster

merges fast.  This performs 20x-25x faster than fts1 when loading the
Enron corpus, and is only slightly slower for queries. (CVS 3474)

docListRestrictColumn() generates a DL_POSITIONS doclist, which means
that after the first doclist is processed, the second doclist is
