8b3554279c dup() the input fd for fast-import used for remote helpers
When a remote helper exposes the "import" capability, stdout of the
helper is sent to stdin of a new fast-import process. This is done by
setting the corresponding child_process's in field to the value of the
out field of the helper child_process.

The child_process API is defined to close the file descriptors it's
given when calling start_command. This means when start_command is
called for the fast-import process, its input fd (the output fd of the
helper), is closed.

But when the transport helper is later destroyed, in disconnect_helper,
its input and output are closed, which means close() is called with
an invalid fd (since it was already closed as per above). Or worse, with
a valid fd owned by something else (since fd numbers can be reused).

56bea28036 pkt-line: drop 'const'-ness of a param to set_packet_header()
The function's definition has a paramter of type "int" qualified as
"const".  The fact that the incoming parameter is used as read-only
in the fuction is an implementation detail that the callers should
not have to be told in the prototype declaring it (and "const" there
has no effect, as C passes parameters by value).

The prototype defined for the function in pkt-line.h lacked the
matching "const" for this reason, but apparently some compilers
(e.g. MS Visual C 2017) complain about the parameter type mismatch.

Let's squelch it by removing the "const" that is pointless in the
definition of a small and trivial function like this, which would
not help optimizing compilers nor reading humans that much.

abd0f28983 test-lib: try harder to ensure a working jgit
The JGIT prereq uses `type jgit` to determine whether jgit is present.
While this is usually sufficient, it won't help if the jgit found is
badly broken.  This wastes time running tests which fail due to no fault
of our own.

Use `jgit --version` instead, to guard against cases where jgit is
present on the system, but will fail to run, e.g. because of some JRE
issue, or missing Java dependencies.  Checking that it gets far enough
to process the '--version' argument isn't perfect, but seems to be good
enough in practice.  It's also consistent with how we detect some other
dependencies, see e.g. the CURL and UNZIP prerequisites.

105df73e71 worktree add: be tolerant of corrupt worktrees
find_worktree() can die() unexpectedly because it uses real_path()
instead of the gentler version. When it's used in 'git worktree add' [1]
and there's a bad worktree, this die() could prevent people from adding
new worktrees.

The "bad" condition to trigger this is when a parent of the worktree's
location is deleted. Then real_path() will complain.

Use the other version so that bad worktrees won't affect 'worktree
add'. The bad ones will eventually be pruned, we just have to tolerate
them for a bit.

[1] added in cb56f55c16 (worktree: disallow adding same path multiple
    times, 2018-08-28), or since v2.20.0. Though the real bug in
    find_worktree() is much older.

581d2fd9f2 get_oid: handle NULL repo->index
When get_oid() and its helpers see an index name like ":.gitmodules",
they try to load the index on demand, like:

  if (repo->index->cache)
	repo_read_index(repo);

However, that misses the case when "repo->index" itself is NULL; we'll
segfault in the conditional.

This never happens with the_repository; there we always point its index
field to &the_index. But a submodule repository may have a NULL index
field until somebody calls repo_read_index().

This bug is triggered by t7411, but it was hard to notice because it's
in an expect_failure block. That test was added by 2b1257e463 (t/helper:
add test-submodule-nested-repo-config, 2018-10-25). Back then we had no
easy way to access the .gitmodules blob of a submodule repo, so we
expected (and got) an error message to that effect. Later, d9b8b8f896
(submodule-config.c: use repo_get_oid for reading .gitmodules,
2019-04-16) started looking in the correct repo, which is when we
started triggering the segfault.

With this fix, the test starts passing (once we clean it up as its
comment instructs).

Note that as far as I know, this bug could not be triggered outside of
the test suite. It requires resolving an index name in a submodule, and
all of the code paths (aside from test-tool) which do that either load
the index themselves, or always pass the_repository.

Ultimately it comes from 3a7a698e93 (sha1-name.c: remove implicit
dependency on the_index, 2019-01-12), which replaced a check of
"the_index.cache" with "repo->index->cache". So even if there is another
way to trigger it, it wouldn't affect any versions before then.

8a30a1efd1 index-pack: prefetch missing REF_DELTA bases
When fetching, the client sends "have" commit IDs indicating that the
server does not need to send any object referenced by those commits,
reducing network I/O. When the client is a partial clone, the client
still sends "have"s in this way, even if it does not have every object
referenced by a commit it sent as "have".

If a server omits such an object, it is fine: the client could lazily
fetch that object before this fetch, and it can still do so after.

The issue is when the server sends a thin pack containing an object that
is a REF_DELTA against such a missing object: index-pack fails to fix
the thin pack. When support for lazily fetching missing objects was
added in 8b4c0103a9 ("sha1_file: support lazily fetching missing
objects", 2017-12-08), support in index-pack was turned off in the
belief that it accesses the repo only to do hash collision checks.
However, this is not true: it also needs to access the repo to resolve
REF_DELTA bases.

Support for lazy fetching should still generally be turned off in
index-pack because it is used as part of the lazy fetching process
itself (if not, infinite loops may occur), but we do need to fetch the
REF_DELTA bases. (When fetching REF_DELTA bases, it is unlikely that
those are REF_DELTA themselves, because we do not send "have" when
making such fetches.)

To resolve this, prefetch all missing REF_DELTA bases before attempting
to resolve them. This both ensures that all bases are attempted to be
fetched, and ensures that we make only one request per index-pack
invocation, and not one request per missing object.

567fce1e10 parse-options: adjust parse_opt_unknown_cb()s declared return type
In f41179f16b (parse-options: avoid magic return codes, 2019-01-27),
the signature of the low-level parse-opt callback function was changed
to return an `enum`.

And while the implementations were changed, one declaration was left
unchanged, still claiming to return `int`.

This can potentially lead to problems, as compilers are free to choose
any integral type for an `enum` as long as it can represent all declared
values.

a505f62f6f Merge branch 'jc/make-dedup-ls-files-output'
A "ls-files" that emulates "find" to enumerate files in the working
tree resulted in duplicated Makefile rules that caused the build to
issue an unnecessary warning during a trial build after merge
conflicts are resolved in working tree *.h files but before the
resolved results are added to the index.  This has been corrected.

* jc/make-dedup-ls-files-output:
  Makefile: dedup list of files obtained from ls-files
