Regenerate Makefile.in for dijkstra after commit 64e1ea3.

Forgot to commit the regenerated file Makefile.in after commit 64e1ea3.

ChangeLog:

	* src/dijkstra/Makefile.in: Regenerate after commit 64e1ea3.
Merge sglib-arraysort and sglib-arraysort1 tests.

The sglib-arraysort and sglib-arraysort1 tests are based on example code
shipped with sglib.  These two tests used different API to access the
sort routines, and also used different sort algorithms (heap vs quick).

For BEEBS we don't care about the different APIs, these make very
little, or no, difference to performance, however, the different search
algorithms might.

This patch merges the two array sorts together, using one API approach,
but testing both sort algorithms.

ChangeLog:

	* configure.ac: Remove sglib-arraysort1.
	* configure: Regenerate.
	* src/sglib-arraysort/Makefile.am: Add support for quick sort and
	heap sort variants.
	* src/sglib-arraysort/Makefile.in: Regenerate.
	* src/sglib-arraysort/arraysort.c (benchmark): Add quick sort and
	heap sort variants.
	* src/sglib-arraysort/sglib.h (SGLIB___ARRAY_HEAP_DOWN): Remove
	unused variable _t_.
	* src/sglib-arraysort1/Makefile.am: Removed.
	* src/sglib-arraysort1/arraysort1.c: Removed.
	* src/sglib-arraysort1/sglib.h: Removed.
	* src/sglib-arraysort1/Makefile.in: Removed.
Add GPL headers to sglib-* tests.

The sglib can be licensed under GPL, so add GPL headers to these files.

	* src/sglib-arraysort/sglib.h: Add GPL header.
	* src/sglib-dllist/sglib.h: Add GPL header.
	* src/sglib-hashtable/sglib.h: Add GPL header.
	* src/sglib-listinsertsort/sglib.h: Add GPL header.
	* src/sglib-listsort/sglib.h: Add GPL header.
	* src/sglib-queue/sglib.h: Add GPL header.
