This better matches the print function which they replace, and prevents
errors from passing the wrong number of arguments. We also change
printing in one function to be more user-friendly.

`git cl split` allows users to parameterize their CL descriptions
by including the string $directory, which is replaced by the list of
directories covered by each generated CL. However, as we add more ways
of generating splittings, a list of directories may not always be the
most appropriate description. For example, the --from-file option lets
users write arbitrary description strings.
This CL renames the $directory string to $description, to reflect this
new generality, and refactors all places in the code that expected a
directory list instead of a string. Since users may beused to the
current version, it does not remove $directory, but instead notes that
it is deprecated and emits a warning when it is used. After some time,
we can remove it entirely.

Currently, the dry run setting causes the script to print out extremely
detailed information about the splitting it generated. While this is
sometimes useful, often users only care about the overall shape of the
splitting. This CL adds a flag which lets them see the same brief
summary that's printed during full runs.

This CL replaces the builtin print function with an alias `Emit`.
This is symmetric with `EmitWarning`, and primarily serves to allow

`git cl split` claims to have built-in auto-resume capabilities, but
the nondeterminism in its splitting algorithm means they don't work
in practice. Now that we have the ability to load splittings from
files, we can ensure the user is using the same splitting as before,
and resume safely.
This CL does two things:
- It checks that any existing split branches match the splitting we're
about to upload, and complains if they don't match. This relies on
the fact that our branch names are unique and deterministic.
- It changes the auto-resume message to mention that --from-file is
required, and includes the relevant filename. This requires tracking
that filename from earlier in the program.

This CL implements the proposal (from the design doc in the cited bug)
to allow `git cl split` to save the generated splitting to a
human-readable and editable text file. This allows users to save the
splitting in case something goes wrong and they need to retry, and also
lets them tweak a generated splitting if they get something mostly, but
not quite, usable.
It also allows users to edit the generated splitting interactively, like
they do for e.g. CL descriptions during `git cl upload`.

This CL changes the way `git cl split` generates branch names during
upload. Specifically, it attempts to derive a common directory for all
the files in each CL, and includes that dirname as part of the branch
name, in addition to a hash of the files in the CL. This makes it a bit
easier to guess what's in a branch, given its name.
Since the hash is still included, branch names should remain unique.
Finding a common directory should be deterministic, so we can still rely
on branches having the same name if the script is re-run with the same
splitting.

`git cl split` operates by creating a new git branch for each CL
it uploads. It names this branch based on the directory of the files
in the CL. It uses this convention when resuming an interrupted upload:
it skips branches that already exist.
However, this approach is brittle for several reasons:
- The splitting is nondeterministic, so there's no guarantee that CLs
with the same directories will be generated when re-run. Even if they
are, there's no guarantee they'll have exactly the same files.
- For CLs with multiple directories, it uses an arbitrary one, so it
may not choose the same name a second time
- It bakes in an assumption that every CL is defined by the directories
it draws files from.
This CL alleviates this issues by instead naming branches using the hash
of their contained files. This ensures that, with extremely high
probability, branches will have the same name if and only if they have
the same (sorted) list of files. Thus resumed uploads can safely skip
existing branches.

`git cl split` has the potential to do a lot of operations at once,
which is problematic if it didn't end up splitting things in a way
the user approves of. This changes it to print a summary of the
splitting, and asking the user to review it briefly before proceeding
with the upload.

I frequently find myself running `git cl split` just to see how the
files are going to be split up, without actually intending to submit the
resulting CLs immediately. Doing so requires creating a file, putting a
dummy description in it, and passing that to the command line, which is
unnecessary work. This CL simply allows dry runs to use a dummy
description if none is provided, to make checking the tool's output
easier.
