changegroup: avoid large copies
- handle chunk headers separately rather than prepending them to
(potentially large) chunks
- break large chunks into 1M pieces for compression
- don't prepend file metadata onto (potentially large) file data

revlog: generate trivial deltas against null revision
To avoid extra memory usage and performance issues with large files,
generate a trivial delta header for deltas against the null revision
rather than calling the usual delta generator.
We append the delta header to meta rather than prepending it to data
to avoid a large allocate and copy.

bdiff: switch to lyhash
lyhash is a very simple and fast hash function that had the fewest
hash collisions on a 3.9M line text corpus and 190k line binary corpus
and should have significantly fewer collisions than the current hash
function.
