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

-# 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.  Extract the version number
-# from in this file.  The versioon number is needed to generate the header
-# comment of the amalgamation.

-** This file is an amalgamation of many separate C source files from SQLite
-** version $VERSION.  By combining all the individual C code files into this 
-** single large file, the entire code can be compiled as a one translation
-** unit.  This allows many compilers to do optimizations that would not be
-** possible if the files were compiled separately.  Performance improvements
-** of 5% are more are commonly seen when SQLite is compiled as a single
-** translation unit.
-**
-** This file is all you need to compile SQLite.  To use SQLite in other
-** programs, you need this file and the "sqlite3.h" header file that defines
-** the programming interface to the SQLite library.  (If you do not have 
-** the "sqlite3.h" header file at hand, you will find a copy embedded within
-** the text of this file.  Search for "Begin file sqlite3.h" to find the start
-** of the embedded sqlite3.h header file.) Additional code files may be needed
-** if you want a wrapper to interface SQLite with your choice of programming
-** language. The code for the "sqlite3" command-line shell is also in a
-** separate file. This file contains only code for the core SQLite library.
-**
-** This amalgamation was generated on $today.
