Retire NETSMBCRYPTO as a kernel option and make its functionality

Browse Source 
enabled by default in NETSMB and smbfs.ko.

With the most of modern SMB providers requiring encryption by
default, there is little sense left in keeping the crypto part
of NETSMB optional at the build time.

This will also return smbfs.ko to its former properties users
are rather accustomed to.

Discussed with:		freebsd-stable, re (scottl)
Not objected by:	bp, tjr (silence)
MFC after:		5 days

developers choose to disable these features on build machines
to maximize performance.
20060305:
The NETSMBCRYPTO kernel option has been retired because its
functionality is always included in NETSMB and smbfs.ko now.
20060303:
The TDFX_LINUX kernel option was retired and replaced by the
tdfx_linux device. The latter can be loaded as a kernel module.
