7541522753 Rename all symbols in libmp(3) to mp_*, just like Solaris.
The function pow() in libmp(3) clashes with pow(3) in libm. We could
rename this single function, but we can just take the same approach as
the Solaris folks did, which is to prefix all function names with mp_.

libmp(3) isn't really popular nowadays. I suspect not a single
application in ports depends on it. There's still a chance, so I've
increased the SHLIB_MAJOR and __FreeBSD_version.

7aa7324a8f Convert telnetd(8) to use posix_openpt(2).
Some time ago I got some reports MPSAFE TTY broke telnetd(8). Even
though it turned out to be a different problem within the TTY code, I
spotted a small issue with telnetd(8). Instead of allocating PTY's using
openpty(3) or posix_openpt(2), it used its own PTY allocation routine.
This means that telnetd(8) still uses /dev/ptyXX-style devices.

I've also increased the size of line[]. Even though 16 should be enough,
we already use 13 bytes ("/dev/pts/999", including '\0'). 32 bytes gives
us a little more freedom.

Also enable -DSTREAMSPTY. Otherwise telnetd(8) strips the PTY's pathname
to the latest slash instead of just removing "/dev/" (e.g. /dev/pts/0 ->
0, instead of pts/0).

e1492a80cd Correct a pair of buffer overflows in the telnet(1) command:
(CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
 functions.

 (CAN-2005-0469) A global uninitialized data section buffer overflow in
 slc_add_reply() and related functions.

As a result of these vulnerabilities, it may be possible for a malicious
telnet server or active network attacker to cause telnet(1) to execute
arbitrary code with the privileges of the user running it.

a6a592c797 Background:
When libdes was replaced with OpenSSL's libcrypto, there were a few
 interfaces that the former implemented but the latter did not.  Because
 some software in the base system still depended upon these interfaces,
 we simply included them in our libcrypto (rnd_keys.c).

Now, finally get around to removing the dependencies on these
interfaces.  There were basically two cases:

  des_new_random_key -- This is just a wrapper for des_random_key, and
     these calls were replaced.

  des_init_random_number_generator et. al. -- A few functions were used
     by the application to seed libdes's PRNG.  These are not necessary
     when using libcrypto, as OpenSSL internally seeds the PRNG from
     /dev/random.  These calls were simply removed.

Again, some of the Kerberos 4 files have been taken off the vendor
branch.  I do not expect there to be future imports of KTH Kerberos 4.
