2014-09-17  Niels Möller  <nisse@lysator.liu.se>

	* testsuite/curve25519-dup-test.c: Deleted file. In the way for
	conversion to Edwards coordiante convention, and in the end
	the tests will be done by ecc-dup-test.c.
	* testsuite/curve25519-add-test.c: Similarly deleted.
	* testsuite/Makefile.in (TS_HOGWEED_SOURCES): Removed
	curve25519-dup-test.c and curve25519-add-test.c.

	* curve25519-mul.c (curve25519_mul): Switch to use Montgomery
	ladder. About 20% faster than current Edwards curve operations.
	Difference is expected to shrink when Edwards operations are
	optimized to take advantage of the twist, but it seems unlikely to
	get significantly faster than the Montgomery ladder.

	* Makefile.in: Revert 2013-02-06 Makefile changes: use a single
	rule for transforming .asm to .o, and drop include of asm.d.
	Possible now since we generate a single object file from each asm
	file. This change also helps Solaris' make recognize .asm files.

	(COMPILE, COMPILE_CXX): Drop CCPIC. New variable EXTRA_CFLAGS,
	which can be set by individual Makefiles.
