The use case is
tar -xzf bigproject.tar.gz
cd bigproject
git init
git add .
# git grep or something
The first add will generate a bunch of loose objects. With --bulk, all
of them are forced into a single pack instead, less clutter on disk
and maybe faster object access.
This is the equivalent of "git -c core.bigFileThreshold=0 add ." so
it's not really a new functionality. Just some convenient and public
exposure.

Interestingly index_stream() seems a bit slower than standard
index_core(). Perhaps mmap() is faster than a series of read() for
small files. Room for improvement later.
