Consdiff: use lengths on inputs so they don't need NUL at the end
5595b21 
This is part of #27244, so that we can safely mmap consensus
documents.
@nmathewson
Stop memcpy'ing uncompressed consensuses when making diffs

@nmathewson
Revise networkstatus parsing code to use lengths
abaca3f 
This way the networkstatus can be parsed without being
NUL-terminated, so we can implement 27244 and mmap our consensus objects.
@nmathewson
Replace "read consensus from disk" with "map consensus from disk".
7e3005a 
Implements 27244, and should save a bunch of RAM on clients.
@nmathewson
Followup: Make authority_cert_parse_from_string() take length too
