The deflate loop in bulk-checkin::stream_to_pack expects to get all bytes
from a file that it requests to read in a single function call. But it
used xread(), which does not give that guarantee. Replace it by
read_in_full().

This extends the earlier approach to stream a large file directly from the
filesystem to its own packfile, and allows "git add" to send large files
directly into a single pack. Older code used to spawn fast-import, but the
new bulk-checkin API replaces it.
