The command line

	$ git clone --mirror $URL

is now a short-hand for

	$ git clone --bare $URL
	$ (cd $(basename $URL) && git remote add --mirror origin $URL)

The -u option to override the remote system's path to git-upload-pack was
being ignored by "git clone"; caused by a missing call to
transport_set_option to set TRANS_OPT_UPLOADPACK. Presumably this crept in
when git-clone was converted from shell to C.

The function has to do three small and independent tasks, but all of them
were crammed into a single loop. This rewrites the function entirely by
unrolling these tasks.

We also now use is_dir_sep(c) instead of c == '/' to increase portability.

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form.  So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.

This patch makes git commands show the dash-less version.

For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

Once a clone is successful we no longer need to hold onto the
.keep file created by the transport.  Delete the file so we
can later repack the complete repository.

After initializing the config in the newly-created repository, we
need to unset GIT_CONFIG so that the global configs are read again.

When we call "git clone" with a url that has a rewrite rule in either
$HOME/.gitconfig or /etc/gitconfig, the URL can be different from
what the command line expects it to be.

So, let's use the URL as the remote structure has it, not the literal
string from the command line.

The shell version used to use "mkdir -p" to create the repo
path, but the C version just calls "mkdir". Let's replicate
the old behavior. We have to create the git and worktree
leading dirs separately; while most of the time, the
worktree dir contains the git dir (as .git), the user can
override this using GIT_WORK_TREE.

We can reuse safe_create_leading_directories, but we need to
make a copy of our const buffer to do so. Since
merge-recursive uses the same pattern, we can factor this
out into a global function. This has two other cleanup
advantages for merge-recursive:

  1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually
     creates bar, but this function just creates the leading
     directories.

  2. mkdir_p took a mode argument, but it was completely
     ignored.

In repos with many refs, it is unlikely that most refs will ever change.
This fact is already exploited by "git gc" by executing "git pack-refs"
to consolidate all refs into a single file.

When cloning a repo with many refs, it does not make sense to create the
loose refs in the first place, just to have the next "git gc" consolidate
them into one file. Instead, make "git clone" create the packed refs file
immediately, and forego the loose refs completely.

Particularly for the "alternates" file, if one will be created, we
want a path that doesn't depend on the current directory, but we want
to retain any symlinks in the path as given and any in the user's view
of the current directory when the path was given.

If we use an unsupported transport (e.g., http when curl
support is not compiled in), transport_get reports an error
to the user, but we still get a transport object. We need to
manually check and abort the clone process at that point, or
we end up with a segfault.

Somewhere in the process of finishing up builtin-clone, the update of
the working tree was lost.  This was due to not using the option "merge"
for unpack_trees().
