Pieter Wuille 511a8d406e crypto: Implement RFC8439-compatible variant of ChaCha20 
There are two variants of ChaCha20 in use. The original one uses a 64-bit
nonce and a 64-bit block counter, while the one used in RFC8439 uses a
96-bit nonce and 32-bit block counter. This commit changes the interface
to use the 96/32 split (but automatically incrementing the first 32-bit
part of the nonce when the 32-bit block counter overflows, so to retain
compatibility with >256 GiB output).

Simultaneously, also merge the SetIV and Seek64 functions, as we almost
always call both anyway.
