Conrad Meyer 8298529226 EKCD: Add Chacha20 encryption mode
Add Chacha20 mode to Encrypted Kernel Crash Dumps.

Chacha20 does not require messages to be multiples of block size, so it is
valid to use the cipher on non-block-sized messages without the explicit
padding AES-CBC would require.  Therefore, allow use with simultaneous dump
compression.  (Continue to disallow use of AES-CBC EKCD with compression.)

dumpon(8) gains a -C cipher flag to select between chacha and aes-cbc.
It defaults to chacha if no -C option is provided.  The man page documents this
behavior.
