Purpose of this is to allow us to avoid re-downloading everything
every time we rebuild the chroot.
This maintains two directories; host and target. Future enhancement
involves collapsing this into one- this requires some host work however,
and has some potential gotchas in doing so.
Meanwhile, we now store distfiles in repo/distfiles/{host,target},
and mount bind repo/distfiles into /var/cache/distfiles.
An upgrade script in turn optimistically tries to move the content
into the new location; if it can't complete the move, it wipes the
content and the user has to redownload it (acceptable, if annoying).

Now that make_chroot.sh lives alongside enter_chroot, we're able
to invoke it directly and use internal options not exposed through
cros_sdk. Thus enter_chroot grows a --early_make_chroot flag.
This flag bypasses the normal sudo usage, and runs the command
as root. It is needed and used by make_chroot for when sudo
may not yet exist (--bootstrap via stage3 lacks sudo).
For where sudo exists and we need access to the source tree,
distfiles, or profile sourcing, enter_chroot is directly used.
For all other invocations we use a single sudo chroot call to
bypass the overhead of enter_chroot.
This is a complete fix to chromium-os:25697 while addressing
all refactoring requests that came up in I8a6c5a26.
Finally, convert all comments into complete sentences, upper
case the leading word, etc to keep reviewers happy.
