Log Message:
Pull up following revision(s) (requested by christos/knakahara in ticket #37):
        sys/opencrypto/crypto.c: 1.79-1.86
        sys/opencrypto/cryptodev.h: 1.35, 1.36
use crypto_checkdriver_uninit() when it may touch uninitialized crypto_drivers.
--
fix reading crp_q without holding crypto_q_mtx
--
restructure locks(1/2): make relation between lock and data explicit.
    + crypto_drv_mtx protects
      -  whole crypto_drivers
    + crypto_drivers[i].cc_lock (new) protects
      - crypto_drivers[i] itself
      - member of crypto_drivers[i]
    + crypto_q_mtx protects
      - crp_q
      - crp_kq
    + crypto_ret_q_mtx protects
      - crp_ret_q
      - crp_ret_kq
      - crypto_exit_flag
I will add locking note later.
--
restructure locks(2/2): crypto_q_mtx can be adaptive now.
--
add locking notes.
--
avoid crp_q reordering as hardware interrupts.
crypto_{,k}invoke() can be called with holding crp_q_mtx now.
--
apply the same fix as crypto.c:r1.83 for crypto_dispatch to crypto_kdispatch.
--
- acquire lock
- use c99 loop indexes
- initialize featp
--
Put back crypto_checkdriver(); use it when we need to make sure that we
get back a cryptocap that has been initialized.
