symm/rijndael-*.S (rijndael_setup_*): Roll up the inner loop.
Reduce code size by tracking position in the main key-schedule loop in a
register and dispatching rather than tracking it in the program-counter.

symm/rijndael-arm-crypto.S (rijndael_setup_arm_crypto): Avoid reload.
Juggle the register allocation in the loop which copies over the first
key-data cycle, so as to arrange to leave the last copied key word in
r4. Then we can elide the explicit load of r4 at the start of the main
key expansion loop, because it already has the right value, saving a
whole instruction.

symm/rijndael-arm-crypto.S (rijndael_setup_arm_crypto): Renumber labels.
Be more consistent about the label numbering. Specifically, 0 is
usually a loop head, and 9 is usually a thing to do next.

symm/rijndael-arm-crypto.S (rijndael_setup_arm_crypto): Fix missing label.
The loop which copies the initial key data from a misaligned address
ends with a branch to the next label 9 which, due to an oversight on my
part, skipped out the setup for the main loop. Introduce an extra label
9 to fix this.

configure.ac: Use modern version of `AC_CHECK_TYPES'.
Also, check for `socklen_t' in <sys/socket.h>, so that we can find it on
Android. I don't expect this to be the last Android portability
failure, because I've not even tried building it there yet.

If the system assembler doesn't like the GNUish directive syntax I'm
using, then the build will fail badly and be hard to fix. Now, if the
assembler doesn't look like it's going to work, then declare the target
platform to be unknown so as to disable all of this fancy machinery.
