jhb a643b1d159 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
