In __gitcomp_file_direct() we tell Bash that it should handle our
possible completion words as filenames with the following piece of
cleverness:
# use a hack to enable file mode in bash < 4
compopt -o filenames +o nospace 2>/dev/null ||
compgen -f /non-existing-dir/ > /dev/null
Unfortunately, this makes this function always return with error
when it is not invoked in real completion, but e.g. in tests of
't9902-completion.sh':
- First the 'compopt' line errors out
- either because in Bash v3.x there is no such command,
- or because in Bash v4.x it complains about "not currently
executing completion function",
- then 'compgen' just silently returns with error because of the
non-existing directory.
Since __gitcomp_file_direct() is now the last command executed in
__git_complete_index_file(), that function returns with error as well,
which prevents it from being invoked in tests directly as is, and
would require extra steps in test to hide its error code.
So let's make sure that __gitcomp_file_direct() doesn't return with
error, because in the tests coming in the following patch we do want
to exercise __git_complete_index_file() directly,
__gitcomp_file() contains the same construct, and thus it, too, always
returns with error. Update that function accordingly as well.
While at it, also remove the space from between the redirection
operator and the filename in both functions.

Rename `git_merge_trees()` to `unpack_trees_start()` and extract the
call to `discard_index()` into a new function `unpack_trees_finish()`.
As a result, these are called early resp. late in `merge_trees()`,
making the resource handling clearer. A later commit will expand on
that, teaching `..._finish()` to free more memory. (So rather than
moving the FIXME-comment, just drop it, since it will be addressed soon
enough.)
Also call `..._finish()` when `merge_trees()` returns early.

After we initialize the various fields in `opts` but before we actually
use them, we might return early. Move the initialization further down,
to immediately before we use `opts`.
This limits the scope of `opts` and will help a later commit fix a
memory leak without having to worry about those early returns.

Teach fetch to generate ref-prefixes, to be used for server-side

When using protocol v2 a client constructs a list of ref-prefixes which
are sent across the wire so that the server can do server-side filtering
of the ref-advertisement. The logic that does this exists for both
fetch and push (even though no push support for v2 currently exists yet)
and is roughly the same so lets consolidate this logic and make it
general enough that it can be used for both the push and fetch cases.

In a later patch we want to improve submodule merging by using the output()
function in merge-recursive.c for submodule merges to deliver a consistent
UI to users.
To do so we could either make the output() function globally available
so we can use it in submodule.c#merge_submodule(), or we could integrate
the submodule merging into the merging code. Choose the later as we
generally want to move submodules closer into the core.
Therefore we move any function related to merging submodules
(merge_submodule(), find_first_merges() and print_commit) to
merge-recursive.c. We'll keep add_submodule_odb() in submodule.c as it
is used by other submodule functions. While at it, add a TODO note that
we do not really like the function add_submodule_odb().

This is the logical continuum of fb43e31f2b (submodule: try harder to
fetch needed sha1 by direct fetching sha1, 2016-02-23) and fixes it as
some assumptions were not correct.
The commit states:
> If $sha1 was not part of the default fetch ... fail ourselves here
> assumes that the fetch_in_submodule only fails when the serverside does
> not support fetching by sha1.
There are other failures, why such a fetch may fail, such as
fatal: Couldn't find remote ref HEAD
which can happen if the remote side doesn't advertise HEAD and we do not
have a local fetch refspec.
Not advertising HEAD is allowed by the protocol spec and would happen,
if HEAD points at an unborn branch for example.
Not having a local fetch refspec can happen when submodules are fetched
shallowly, as then git-clone doesn't setup a fetch refspec.
So do try even harder for a submodule by ignoring the exit code of the
first fetch and rather relying on the following is_tip_reachable to
see if we try fetching again.

The last two tests 'editor with a space' and 'core.editor with a

ensure that they are only run on filesystems that allow, well, spaces
in filenames. However, we have been putting a space in the name of
the trash directory for just over a decade now, so we wouldn't be able
to run any of our tests on such a filesystem in the first place.
This prereq is therefore unnecessary, remove it.
