722a7e9ab3 Modify the VFS xAccess() method on winNT so that it returns false for 
an exists test of a zero-length file.  This makes the windows VFS work
the same as the unix VFS.

3e875ef3b5 Allocate a buffer containing the full path-name to the associated WAL file when a pager is created. This saves having to construct a new buffer each time a new read-transaction is opened and SQLite checks for the existance of a WAL file.
