Log Message:
Clean up userlevel access to software kernel transforms, in preparation
for using /dev/crypto for OpenSSL:

1. Add comments explaining crypto_devallowsoft, explaining the
OpenBSD-style three-way logic actully implemented in crypto_newsession().

2. Pass crypto_devallowsoft as the final argument to crypto_newsession(),
instead of a constant 0 value.

3. Set the default value of crypto_devallowsoft to 1, to allow
/dev/crypto access only for hardware-supported transforms.

Items 1-3 may be revised to match the FreeBSD two-way logic, if the
consensus is that there's no point to forcing software transforms.
But as a first step, let the description match what the code actually does.

GC unused variables usercrypto, userasmcrypto, cryptodevallowsoft from
cryptodev.c, in favour of variables crypto_usercrypto, crypto_userasmcrypto,
crypto_devallowsoft, which are used as well as defined in crypto.c.
