bf0016a888 Implement double- and triple-DES. 
Single-DES is now a special case of triple-DES with all three keys being the same.  This is significantly slower than a pure single-DES implementation, but that's fine since nobody should be using it anyway.

371d519169 Implement the Salsa family of stream ciphers. 
Note that we only have unit tests for Salsa20.

1073dceed9 Second iteration of the cryb-cipher API. 
We now have separate encryption and decryption methods, and can process an arbitrary amount of plaintext or ciphertext per call, rounded down to the block size (if applicable).  For stream ciphers, we also have a keystream method which fills the provided buffer with an arbitrary amount of keystream (once again, rounded down if applicable).

52cf1f9d3c Rename t_verbose*() to t_printv*(). 
Not only is this a slightly more logical name, but it allows us to expose the verbose flag, previously private to cryb_t_main.c, as the equally logically named t_verbose.

d419d7388a Remove an unnecessary pointer from struct aes_ctx. 
The rk pointer in struct aes_ctx always pointed to the context's buffer and served no purpose whatsoever, but the compiler had no way of knowing that and could therefore not optimize away assignments to and from it.

Note that the removal of rk breaks the ABI, since it changes the size of struct aes_ctx, but we allow ourselves that because neither the API nor the ABI have been fixed yet.

856571a06d Implement a soft assert for unit tests. 
Unlike assert(3), which uses abort(3), this has no other side effects (before raising SIGABRT) than an fprintf() call.  The test framework will catch the SIGABRT, report that the test case failed, and proceed with the next case.

401465d8ea Move main() from libcryb-test to the test program. 
Instead of having libcryb-test provide main() and assume that the test program defines t_prepare() and t_cleanup(), have libcryb-test provide a t_main() function which the test program calls with pointers to its prepare and cleanup functions.

955cbc3013 Add t_malloc_snapshot() which writes a snapshot of the allocator state to 
a caller-provided buffer.  Use it to warn about leaks in each individual
test case.  Note that we can't fail a test case for leaking, because
individual test cases in a unit may modify shared state which is cleaned
up at the end of the series.
