77ae7ca643 Avoid an unnecessary initialization of the szFile field of unixFile in 
the unix VFS.

4fd7111dcb Enhance the unix VFS so that it keeps track of the size of unlinked files 
internally and thus avoids the need to call fstat() on those files, since
fstat() does not work reliably on unlinked files on some implementations
of FuseFS.

62a223e5dd Modify the %nonassoc directive in lemon so that it generates a run-time 
error rather than a parsing conflict.  This changes is due to a bug report
on the mailing list.  SQLite does not use the %nonassoc directive in its
grammar so this change does not affect SQLite.

c94b2f7d6b Make sure the estLog() routine in the query planner handles negative 
values correctly (always returning 1).  Prior to this change, estLog(-1)
would return a large number which could throw off the cost computations
in the query planner in obscure circumstances.
