When the surrounding code is already heavily based upon the
assumption that we have a FileRepository (e.g. because it
created that type of repository) keep the type around and
use it directly. This permits us to continue to do things
like save the configuration file.

To support other storage models other than just the local filesystem,
we split the Repository class into a nearly abstract interface and
then create a concrete subclass called FileRepository with the file
based IO implementation.
We are using an abstract class for Repository rather than the much
more generic interface, as implementers will want to inherit a large
array of utility functions, such as resolve(String). Having these in
a base class makes it easy to inherit them.
This isn't the final home for lib.FileRepository. Future changes
will rename it into storage.file.FileRepository, but to do that we
need to also move a number of other related class, which we aren't
quite ready to do.

If the working tree isn't available, it doesn't make any sense to
obtain the merge heads, or the buffered commit message. The

Its not strictly required that we sort topologically in order to
produce a valid pack file. This was just something that Linus
thought would be a good idea to do. In practice its not that
important for most repositories. Local file IO quickly falls
out of the pattern that topological sorting provides any sort
of benefit for, so expending extra resources to enforce it when
we make a pack isn't really worth it.
I'm removing this sort in the pipeline because later changes
would support really efficient COMMIT_TIME_DESC sorting on a
non-file storage system, but TOPO sorting would be a bit more
ugly to run, due to the in-memory delays it imposes.

If UploadPack invokes flush() on the output stream we pass it, its
most likely the progress messages coming down the side band stream.
As pack generation can take a while, we want to push that down
at the client as early as we can, to keep the connection alive,
and to let the user know we are still working on their behalf.
Ensure we dump the temporary buffer whenever flush() is invoked,
otherwise the messages don't get sent in a timely fashion to the
user agent (in this case, git fetch).
We specifically don't implement flush() for ReceivePack right now,
as that protocol currently does not provide progress messages to
the user, but it does invoke flush several times, as the different
streams include '0000' type flush-pkts to denote various end points.

We want to eventually get rid of the mapCommit, mapTree APIs on
Repository and force everyone into the faster parsers that exist
in RevWalk. Rewriting resolve in terms of the faster parsers is
a good first step.
It actually simplifies the code a bit, as we no longer need to
keep track of an ObjectId and an Object (the parsed form), since
all RevObjects implicitly have their ObjectId readily available.

sorting to accept tags that have no tagger identity, because they
were created before Git knew how to store that field.

Rather than relying on the helpers in RepositoryConfig to get

Its only slightly more verbose, but permits us to work with the

A Git reference name must never end with ".lock", as it would
confuse any existing C client that tries to obtain a clone of the
repository over the network. Even if the repository isn't on a
local filesystem, it still should ban that suffix.
Because I plan to move LockFile to storage.file and make it a private
implementation detail of the local file system storage model,
we can't rely on its package level SUFFIX field here. Making it
public probably won't work long-term either, as I also plan to
pull storage.file into its own separate project that depends on
the core library.
So, just inline the constant here. Its as foribidden as ":" is.
