Add GPL header to rijndael benchmark.

According to the licence header it should be fine to add a GPL header
to this code.  I've removed the LICENCE file as the licence is
repeated inside every source file.

ChangeLog:

	* src/rijndael/LICENSE: Removed.
	* src/rijndael/Makefile.am: Remove reference to LICENCE file.
	* src/rijndael/Makefile.in: Regenerate.
	* src/rijndael/aes.c: Add GPL header.
	* src/rijndael/aes.h: Add GPL header.
	* src/rijndael/aestab.h: Add GPL header.
	* src/rijndael/aesxam.c: Add GPL header.
Fix repeated work Suite in header comments.

More places where I caused the work Suite to be duplicated when I
fixed the BEEBS expansion.

ChangeLog:

	* tools/generate-benchmark.sh: Remove duplicate word 'Suite' in
	two places.
	* src/common.mk.am: Remove duplicate word 'Suite'.
	* src/common.mk.in: Regenerate.
	* src/*/Makefile.in: Regenerate.
Fix 'make distcheck'.

Get 'make distcheck' working again.  This is just a case of source
files missing from the SOURCES lists in various places, add the files
to the list and regenerate the makefiles.  The only exception is the
new chipsupport.c file, in this case the generic code places a
dependency on chipsupport.c without checking if the file exists.  For
simplicity I've just added an empty file.

ChangeLog:

	* config/x86_64/chips/generic/chipsupport.c: New file.
	* src/common.mk.am: Add support.h as a source file.
	* src/miniz/Makefile.am: Add miniz.h as a source file.
	* src/qrduino/Makefile.am: Remove exxtable.h, and add ecctable.h
	qrbits.h to the source file list.
	* src/sglib-rbtree/Makefile.am: Add sglib.h as a source file.
	* src/*/Makefile.in: Regenerate.
Remove unneeded src/common.mk.in file.

The file src/common.mk.in is, in theory, generated from
src/common.mk.am by automake, however, as src/common.mk.am is only
ever included into other makefiles, and is not a top level makefile in
it's own right, the *.in version is no longer regenerated, as such the
*.in file is out of date, never actually regenerated, and not needed.

ChangeLog:

	* src/common.mk.in: Deleted.
Add GPL header to some scripts.

ChangeLog:

	* analysis/all_stats.py: Add GPL header.
	* analysis/instruction_stats.py: Add GPL header.
	* analysis/simulator.in: Add GPL header.
	* tools/energytool.py: Add GPL header.
