Merge branch 'np/pack'

* np/pack:
add the capability for index-pack to read from a stream
index-pack: compare only the first 20-bytes of the key.
git-repack: repo.usedeltabaseoffset
pack-objects: document --delta-base-offset option
allow delta data reuse even if base object is a preferred base
zap a debug remnant
let the GIT native protocol use offsets to delta base when possible
make pack data reuse compatible with both delta types
make git-pack-objects able to create deltas with offset to base
teach git-index-pack about deltas with offset to base
teach git-unpack-objects about deltas with offset to base
introduce delta objects with offset to base

  	space. `--depth` limits the maximum delta depth; making it too deep
  	affects the performance on the unpacker side, because delta data needs
  	to be applied that many times to get to the necessary object.
 +	The default value for both --window and --depth is 10.
  
  
+ Configuration
+ -------------
+ 
+ When configuration variable `repack.UseDeltaBaseOffset` is set
+ for the repository, the command passes `--delta-base-offset`
+ option to `git-pack-objects`; this typically results in slightly
+ smaller packs, but the generated packs are incompatible with
+ versions of git older than (and including) v1.4.3; do not set
+ the variable in a repository that older version of git needs to
+ be able to read (this includes repositories from which packs can
+ be copied out over http or rsync, and people who obtained packs
+ that way can try to use older git with it).
