1b78eaf0ba Update header comments in wal.c to correctly describe the WAL file format. 
Update the locking region offsets in os_unix.c and os_win.c and add assert()
statement to verify that the locking region offsets are correct.

with "warning: 'amode' may be used uninitialized in this function".

this compiler warning by doing a simple initialization of the "amode"
variable. (CVS 4436)
