John Baldwin 16aabb761c Remove support for IPsec algorithms deprecated in r348205 and r360202. 
Examples of depecrated algorithms in manual pages and sample configs
are updated where relevant.  I removed the one example of combining
ESP and AH (vs using a cipher and auth in ESP) as RFC 8221 says this
combination is NOT RECOMMENDED.

Specifically, this removes support for the following ciphers:
- des-cbc
- 3des-cbc
- blowfish-cbc
- cast128-cbc
- des-deriv
- des-32iv
- camellia-cbc

This also removes support for the following authentication algorithms:
- hmac-md5
- keyed-md5
- keyed-sha1
- hmac-ripemd160

# There are sample scripts for IPsec configuration by manual keying.
# A security association is uniquely identified by a triple consisting
# of a Security Parameter Index (SPI), an IP Destination Address, and a
# security protocol (AH or ESP) identifier. You must take care of these
# parameters when you configure by manual keying.
# ESP transport mode is recommended for TCP port number 110 between
# Host-A and Host-B. Encryption algorithm is aes-cbc whose key
# is "kamekamekamekamekamekamekamekame", and authentication algorithm is
# hmac-sha2-512 whose key is "this is the test key".
