Update regression tests for current API, add makefiles

The new crypto API uses VAP, so allocate one.  Use keys from
vap->iv_nw_keys with the provided key index (0 for TKIP), don't allocate
another key on the stack.  Synchronize context structures with the
current code.

Return -ENXIO on failure.  It's hard to find a sensible code for crypto
test failure, but -1 (-EPERM) was misleading.  Fix TKIP test that was
ignoring failures.

Update module parameters for Linux 2.6.  Provide makefiles to facilitate
compilation.  Fix all sparse warnings.
