28eec68c76 Proposed change to the fix for ticket [1c69be2dafc28b] such that legacy 
applications that were exploiting the older buggy behavior in SQLite
continue to work.

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

f5154c6a1c 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.

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.

FROM clause will never return more than one row and hence do not require
sorting.

43ae8f6f4d In the command-line shell, if three or more interrupt signals (control-c) 
are received in a row without a response from sqlite3_interrupt() then
call exit(1) immediately.  This allows control-C to interrupt the shell
even if it is stuck in a computation or loop that does not involve the
VDBE.
