Move bundled copy of sqlite one level deeper to better separate it...

-#!/usr/bin/tclsh
-#
-# To build a single huge source file holding all of SQLite (or at
-# least the core components - the test harness, shell, and TCL 
-# interface are omitted.) first do
-#
-#      make target_source
-#
-# The make target above moves all of the source code files into
-# a subdirectory named "tsrc".  (This script expects to find the files
-# there and will not work if they are not found.)  There are a few
-# generated C code files that are also added to the tsrc directory.
-# For example, the "parse.c" and "parse.h" files to implement the
-# the parser are derived from "parse.y" using lemon.  And the 
-# "keywordhash.h" files is generated by a program named "mkkeywordhash".
-#
-# After the "tsrc" directory has been created and populated, run
-# this script:
-#
-#      tclsh mksqlite3c.tcl
-#
-# The amalgamated SQLite code will be written into sqlite3.c
-#
-
-# Begin by reading the "sqlite3.h" header file.  Count the number of lines
-# in this file and extract the version number.  That information will be
-# needed in order to generate the header of the amalgamation.
